CAGE FOR THE RECEIPT OF HYMENOPTERA

Description

TECHNICAL FIELD OF THE INVENTION

[0001] The present invention relates to a self-contained capture cage for unwanted insects, this model relates to the species Vespa velutina, a hymenoptera more commonly called Asian hornet or yellow-legged hornet. STATE OF THE ART

[0002] The Asian hornet, accidentally imported with Chinese goods in 2004, has proven to be a very invasive pest due to its exponential reproduction rate and its need for meat protein.

[0003] A generalist predator, it impacts many species of useful insects including many pollinators which are the prey of this predator. It is in fact destructive of biodiversity and threatens the food chain by its omnipresence in territories with large fluctuations in density.

[0004] This hornet is capable of destroying entire hives of honeybees in a single season, severely affecting beekeeping activity and accelerating the disappearance of beekeepers by ruining their farms.

[0005] Asian hornets are social insects and therefore live in colonies. These are sheltered in cellulose nests made up of individuals divided into castes, each playing a defined role in the colony. The queen founds the colony and then lays eggs. The workers, unfertilized female workers, remove the larvae, supply the colony with food and build the nest. The young queens ensure the dissemination of the species over a radius of nearly 70km / year (source: Insect Biology Research Institute of Tours). The social bond is ensured by a pheromone produced by the foundress which is specific to each colony (nest). The phenomenon of "trophallaxis", less developed in Vespa velutina than in the honeybee, allows the sharing and exchange of food brought back to the nest by the workers between all the individuals in the colony.The young queen, who has become a "foundress," is at the center of the colony's social network due to her production of pheromones that allow for perfect cohesion. Since the foundress plays a major role in reproduction, her death ultimately leads to the decline of the colony.

[0006] All female social Hymenoptera have a venom-injecting system, that is, a sting capable of injecting venom, which is painful and sometimes dangerous for humans if the venom is severe.

[0007] From a biological point of view, Vespa velutina differs from its European cousin Vespa crabro by several traits, morphological nuances and its exclusively diurnal activity.

[0008] The nest of Vespa velutina is generally built in the open air, very often at the top of large trees, unlike its European cousin which always establishes its nest in pre-existing cavities, well sheltered from the weather.

[0009] Vespa velutina lives better in an anthropized environment than in the countryside. Its nest is also much larger and more populous: it can contain up to 2000 individuals compared to 800 in the case of the Vespa crabro.

[0010] Vespa velutina is particularly efficient in hunting because it is very fast and able to hover. This allows it to capture its prey very efficiently. It carries them away to cut them up and keeps only the thorax with which it will make a pellet that it will bring back to the nest to feed the larvae.

[0011] When an Asian hornet nest has detected an apiary or a nest of social insects, the presence of the hornets hovering in front of the entrance to the hives stresses the bee colonies, which then no longer feed normally: reserves are depleted, the queens stop laying eggs and the colonies collapse due to a lack of food and / or population to maintain a sufficient temperature in the colony.

[0012] The Asian hornet is therefore a scourge for beekeeping activity.

[0013] There is a control technique that allows you to destroy an undiscovered nest by capturing the insect, then handling it and applying an attractant and insecticide. When it returns to the nest, it contaminates the other hornets (using the "Trojan horse" principle). To be implemented, good control is required (because it is necessary to handle them).

[0014] Trapping involves using devices that contain bait that attracts hornets and keeps them captive.

[0015] The vast majority of traps, such as "bottle or bell" traps, are not sufficiently effective because the hornet can make vertical flights, making it possible for them to escape, and they have the major disadvantage of being insufficiently selective.

[0016] As an illustration, US2018 / 0042212 discloses an insect trap using a bottle and a funnel system which, on the one hand, lacks selectivity and, on the other hand, does not allow sufficient diffusion of the olfactory effluvia of a possible bait. A similar principle is found in US 1,386408 which suffers from the same defects (admittedly attenuated). US869556 and WO 2012 / 001442 disclose cages which do not allow species selectivity. WO2016 / 004472A1 discloses an “ovitrap” configured in particular to trap mosquitoes and to allow the collection of information relating to the mosquitoes thus trapped. Not all of these traps allow satisfactory capture. Vespa velutina.

[0017] Another curative control technique involves destroying nests using significant equipment (telescopic pole, spraying equipment), good protection, handling biocides, and possible hornet attack. Electrocuting hornets with an "electric harp" allows the destruction of hornets near hives. All these methods are curative and do not effectively control the species. SUBJECT OF THE INVENTION

[0018] The present invention aims to remedy all these drawbacks.

[0019] To this end, the present invention relates to a selective capture cage (20) for hymenoptera according to claim 1.

[0020] In the context of the present invention, by "funnel" is meant a trap system, or equivalent (e.g. in the shape of a funnel for pouring a liquid), making it possible to channel the insects towards the entrance (passage orifice) in the capture cage. It can therefore theoretically be of any shape as long as it fulfills this function. Preferably, the funnel of the invention is of a generally truncated cone shape, for example of circular, oval or polygonal section such as a triangle, a square, a rectangle, a diamond, a pentagon, a hexagon, a heptagon or even an octagon.

[0021] Preferably, the passage orifice (212) comprises at least one passage limiting section with a dimension greater than 7.0 mm and for example less than 7.23 mm.

[0022] More preferably, the passage orifice (212) comprises at least one passage limiting section with a dimension between 7.17 mm and 7.30 mm, even more preferably between 7.18 mm and 7.25 mm, for example between 7.19 mm and 7.23 mm, such as between 7.20 mm and 7.22 mm.

[0023] Preferably, the funnel section has the shape of a truncated pyramid (213).

[0024] Preferably, the capture cage according to the present invention is characterized in that the limiting passage section of the pores is of a size less than or equal to 12 mm, less than or equal to 11 mm, less than or equal to 7 mm, or less than or equal to 5 mm.

[0025] Advantageously, the capture cage according to the present invention is characterized in that the pores of the porous plate (21) comprise a polygonal shape and / or a rounded shape. Thus, the polygonal shape may be a diamond, for example with a long diagonal of between 14 and 18 mm and a short diagonal of between 5 and 9 mm. In a particular embodiment, the rounded shape consists of a rectangle of which at least one corner is rounded, or even characterized in that at least one side of the rectangle is completely rounded.

[0026] Furthermore, the present invention relates to a cage for capturing hymenoptera comprising a box having a bottom and four walls, two of which walls each comprise an opening for the circulation of effluvia, remarkable in that each opening for the circulation of effluvia comprises a porous plate (such as a mesh plate). Said porous plate (such as a mesh plate) may cover the opening for the circulation of effluvia, and may consist of at least one mesh portion having meshes whose vertical height is less than 0.7 cm. Said porous plate (such as a mesh plate) may comprise a funnel in the shape of a truncated pyramid having a large base and a small base directed towards the interior of the capture cage, said truncated pyramid having a passage orifice corresponding to the small base of the truncated pyramid.

[0027] Thanks to these arrangements, little know-how and little equipment is required. The passage opening will allow all the Asian hornets to enter while preventing them from leaving because the funnel (e.g. the pyramid trunk) directed inwards prevents the hornet(s) from finding the exit. The cage allows for effective preventative control.

[0028] Installing this type of device in the apiary (or elsewhere) will allow bees to escape from the trap cage while retaining only Asian hornets. The mesh dimensions of the porous plate (such as a wire mesh plate) allow bees and other small insects to escape.

[0029] Thus, advantageously, the capture cage according to the present invention is characterized in that the hymenoptera is the species Vespa velutina, and preferably the capture cage is configured to not retain honey bees.

[0030] The invention is advantageously implemented according to the embodiments and variants set out below, which are to be considered individually or in any technically effective combination.

[0031] In one embodiment, the mesh has meshes with a long diagonal of between 14 and 18 mm, a short diagonal of between 5 and 9 mm, a strap of between 0.8 and 1.2 mm and a thickness of between 0.6 and 1 mm.

[0032] In one embodiment, the passage orifice (212) has the shape of a rectangle whose length is between 10 and 30 mm, such as 20 mm, and whose width is 7.21 mm. Thus, the capture cage according to the present invention can be characterized in that the cage is configured such that the length is horizontal to the ground and the width is perpendicular to the ground.

[0033] Preferably, the capture cage (20) according to the present invention is characterized by the distance between the large base and the small base of the funnel being between 10 and 15 cm. In a particular embodiment, the height between the large base and the small base of the pyramid truncated shape may be between 10 and 15 cm.

[0034] In one embodiment, the box has a removable cover (having the property of isolating the interior from the exterior at its level).

[0035] In one embodiment, the two walls each have an opening facing each other.

[0036] In one embodiment, the bottom comprises at least one porous portion (such as a mesh portion) under which a bait is intended to be positioned.

[0037] In one embodiment, the porous plate (such as a mesh plate) comprises a rectangular-shaped flat portion having a length of between 11 and 20 cm and a width of between 7 and 15 cm.

[0038] Furthermore, the subject matter of the present invention relates to a funnel for a capture cage (20) as described by claim 11.

[0039] Thus, preferably, the funnel according to the present invention can be characterized in that the passage orifice (212) has the shape of a rectangle whose length is between 10 and 30 mm, such as 20 mm, and the width is 7.21 mm.

[0040] In a particular embodiment, the funnel according to the present invention can be characterized in that it comprises a porous portion whose limiting passage section of the pores is smaller in size than the limiting passage section of the passage orifice (212).

[0041] Thus, one of the objects according to the present invention relates to a funnel as described herein, characterized in that said funnel has the shape of a truncated pyramid (213).

[0042] Additionally, an object of the present invention relates to a kit for making a funnel as described by claim 12.

[0043] Furthermore, an unclaimed subject matter relates to a kit for a capture cage (20) according to the present invention, characterized in that said kit comprises: a box having a bottom (201), at least three walls, preferably four walls, at least two walls of which each have an opening for attaching a funnel as described above, a funnel as described above, and a lid.

[0044] Another object of the present invention relates to the use of a capture cage (20) according to the present invention to capture at least one hornet, preferably a hornet of the species Vespa velutina (queen capture: preventive use, and / or worker capture: curative use). This use can be characterized in that at least one bait is inserted into the capture cage (20), said at least one bait being optionally positioned and protected under a porous part, such as a mesh part. In this embodiment, the use can be characterized in that said at least one bait is selected from the list consisting of honeyed waxes, red fruit syrup, dark beer, cider or sweet white wine saturated with sugars to which jam and / or honey can be added, or meat material, for example from fish, crustaceans or shellfish, or one of the mixtures thereof.

[0045] The present invention may further relate to the use as described herein, characterized in that islands consisting of small sponges are inserted as diffusers of olfactory effluvia in the capture cage (20). BRIEF DESCRIPTION OF THE FIGURES

[0046] Other advantages, aims and characteristics of the present invention emerge from the following description given, for explanatory and non-limiting purposes, with reference to the appended drawings, in which: there figure 1 , represents a perspective view of the interior of the capture cage of a particular embodiment of the cage which is the subject of the present invention, the figure 2 represents a perspective view of one side of the capture cage of the figure 1 object of the present invention, the figure 3 represents a perspective view of a porous plate (such as a mesh plate), the figure 4represents a mesh of the porous plate (such as a grid plate), the Figure 5 represents the elements of a kit for a truncated pyramid-shaped funnel according to the present invention. figure 6 is a photograph of the result of one of the tests performed, as explained below. DESCRIPTION OF EXAMPLES OF EMBODIMENT OF THE INVENTION

[0047] There figure 1 represents a perspective view of the interior of the capture cage 20.

[0048] There figure 2 represents a perspective view of one side only of the capture cage 20.

[0049] In these figures there is shown a box having a bottom 201 and four walls, two of which have an opening 22 for circulation of the effluvia.

[0050] Each opening 22 for circulation of the effluvia is covered by a porous plate (such as a mesh plate) 21 completely covering the opening 22 for circulation of the effluvia.

[0051] The porous plate (such as a mesh plate) 21 is made of a mesh having meshes whose long diagonal is 16 mm, the short diagonal is 8 mm, the strap is 1 mm and the thickness is 0.8 mm.

[0052] The porous plate (such as a mesh plate) 21 comprises a funnel in the shape of a truncated pyramid 213 having a large base and a small base directed towards the inside of the capture cage 20, said truncated pyramid 213 having a passage orifice 212 corresponding to the small base of the truncated pyramid 213.

[0053] The funnel may be made of any material sufficiently rigid for its implementation, for example metal, organic polymer such as plastic (e.g. PVC) or a biological material such as wood or reconstituted cellulose. Shown here is a funnel in the shape of a truncated pyramid 213 made of expanded metal. In one example, the funnel is thus made of metal, such as aluminum. According to other examples, it is made of other materials which make it possible to maintain the shape of the funnel (such as a truncated pyramid 213). The dimension of the expanded metal may be 16 x 8 x 1 x 0.8 mm and it is fixed on a porous plate (such as a mesh plate) 21 of the same nature.

[0054] The rigid material profile (such as metal) deployed in the chosen format allows bees and other insects of equivalent or smaller size to pass through the pores / meshes (in both directions) with the best conditions of ease and speed.

[0055] The porous plate (such as a mesh plate) 21 is positioned normal to the longitudinal axis of the funnel and allows the circulation of effluvia and a rapid exit of the bees without obstruction. The porous plate (such as a mesh plate) 21 comprises a flat part 211 of rectangular shape whose length is between 11 and 20 cm, for example 15 cm and the width is between 7 and 15 cm, for example 10 cm.

[0056] The porous plate (such as a mesh plate) 21 is arranged as follows: the base of the diamond of the meshes is directed towards the outside for greater ease of exit than of entry. The funnel is fixed to the porous plate (such as a mesh plate) 21 after a 10 x 20 cm cutout in a mesh plate. The fixing is carried out by stapling, tacking, screwing (e.g. on wood, photo), by gluing (glue resin for plastic) or by nylon collar on the capture cage 20 and by an overlap of approximately 1 cm.

[0057] The passage orifice 212 of the funnel (such as a pyramid truncated) 213 porous / mesh, directed towards the interior, allows the easy passage of the Asian hornet queens and, for this purpose, has a calibrated orifice of 7.21 mm high for the effective passage of the thorax of an Asian hornet queen while prohibiting that of a European hornet queen which is approximately 1.5 mm larger in size. This is why it is possible to have an orifice in a range of values ​​around 7.21 mm in order to vary the selectivity of the cage.

[0058] The depth of the funnel (like a truncated pyramid) of the module and its fully ventilated structure is long enough to prevent the Asian hornet from finding the exit (trap principle). The experiments carried out have shown that no Asian hornet that entered has ever left.

[0059] The height (or depth of the funnel) between the large base and the small base of the funnel (such as a truncated pyramid) 213 is 13 cm (between 10 and 15 cm).

[0060] The capture cage 20 preferably comprises two funnels, facing each other to optimize the circulation of effluvia.

[0061] In another example, the two funnels are not opposite each other but for reasons of space, the longitudinal axis of the two funnels is offset from each other.

[0062] The wide opening of the funnel thus ensures the reception and capture of all the Asian hornet queens from the environment of the capture cage 20 over very large distances to the point of no longer risking predation by hunting workers throughout the season to protect an apiary. Capture cage 20 contains bait.

[0063] In one example, the bait is positioned under the bottom 201 of the capture cage 20. The bottom 201 of the capture cage 20 comprises a mesh portion under which a bait is positioned. The assembly consisting of the capture cage 20 and the bait allows the capture of the Asian hornet.

[0064] In another variation, the bait is positioned inside the cage, still with a grid to allow the olfactory odors to be released.

[0065] The bait that has proven most effective is made of honeyed wax (crop cappings or honey frames) which must be protected by fine mesh (like the fine stainless steel mesh used for aerating hive floors) to prevent access to all insects. There are two reasons for this: the need for rapid removal of non-target insects from capture cage 20 (because they cannot access the bait) and to prevent them from becoming prey for Asian hornets already present in capture cage 20; and / or the potential risk of transmission of pathologies by contamination of bees by American foulbrood spores which could be present in honeyed waxes (or wax tree juice). To further limit predation of bees by Asian hornets already captured, it is possible to bring (in season and for curative operation) meat material from raw unprotected fish remains into capture cage 20 (to be replaced every two / three days).This allows flies to be present in the capture cage 20, the latter then becoming the preferred prey of the Asian hornet instead of the bees which no longer stay and only circulate in the capture cage 20, thus becoming less easy prey. Pieces of oily fish (such as leftovers), crustaceans and shellfish are meaty substances highly prized by Asian hornets to feed their offspring.

[0066] For those who do not have honeyed waxes, a mixture of red fruit syrup, dark beer, cider saturated in sugars can be used to which jam or honey can be added (for example from leftover jam or jars of honey forgotten at the bottom of a cupboard). Islands made of small sponges are all diffusers of complementary olfactory scents. It should be remembered that it is only exclusively the odorous scents that exhale from the baits and that will attract Asian hornets. The larger the surface area of ​​the bait, the more effective and wide the range of action of the capture cage 20 is. The very strong attractiveness that allows collection over a very wide radius is linked to a particularly effective bait that can be of several types, placed over a very large surface inaccessible to all insects.This allows for a rapid death of the hornets, respecting the health aspect for the bees (avoiding the transmission of diseases by American foulbrood spores) allowing them to emerge very quickly as well as all other small insects.

[0067] The imperative period is spring to prevent the construction of Asian hornet nests. It allows the capture of queens from the end of March. Given the capture of all the queens, do not take into account the intra-specific competition (fighting between queens) that they have from this period onwards for the usurpation of the nests. From the end of June, the capture of queens is rarer, or even stops.

[0068] For beekeepers, the presence of a 20 capture cage near the apiary is essential from March to November (or simply, until the queen captures stop). Its selective nature allows this. A 20 capture cage installed routinely, each year, on either side of the apiary protects it throughout the bee activity period.

[0069] From the beginning of spring, it is essential to remove from the apiary any dead or weak hive that could become a competitor to the capture cage 20 for the honey it contains (and this is also essential from a health perspective).

[0070] For the beekeeper, the capture cage 20 allows the use of a crystallized honey frame consisting of two supers placed one on top of the other (if you have super honey frames). The first super will contain the honey frames, it is placed on a ventilated hive bottom 201 closed by a nested entrance door on the closing side to prevent any insects from passing through. This super is isolated from the top one by the fine mesh described above to protect the bait (best) from the size of the super or a propolis grid kept away from the frame heads by wedging. The top (empty) super becomes the capture cage 20 for the Asian hornet and is protected by a removable cover. The removable cover has the function of closing the box and functions as a roof whose dimensions are greater than the section of the box (i.e. insulating). If you have hive body frames, the bottom super is replaced by a hive body.

[0071] An alternative: above, instead of a super, so as not to condemn beekeeping equipment, a simple wooden frame made by assembling 4 boards on which are fixed the two mesh plates each with their own funnel. How to eliminate Asian hornets once in capture cage 20?

[0072] At nightfall, the captured Asian hornets present in the 20 capture cage are generally grouped on a social hymenoptera wall. The Asian hornets to be destroyed can be collected in the jar with a small tool (brush... or cordless vacuum cleaner). Freezing or crushing them is one of the solutions for their elimination.

[0073] Installing a 20 capture cage is also very important in case of attacks on the hives, in summer and autumn, Asian hornets enter them in large numbers.

[0074] The selective spring capture of all Asian hornet queens in an area remains, to date, the only simple and inexpensive preventive control method that gives real results in terms of regulating the Invasive Exotic Species (IAS). Vespa velutina nigrithorax.

[0075] There figure 3 represents a porous plate (such as a mesh plate) 21 comprising a truncated pyramid-shaped funnel 213 having a large base and a small base. The truncated pyramid 213 is directed towards the inside of the capture cage 20. The truncated pyramid 213 has a passage orifice 212 corresponding to the small base of the truncated pyramid 213.

[0076] There figure 4 represents a mesh of the platen mesh.

[0077] In one example, the grid is made of expanded metal. The metal is, for example, aluminum.

[0078] Expanded metal is made from sheet metal by cutting and cold drawing. It has very strong meshes stretched in a single operation.

[0079] This figure shows the characteristics of the plate mesh: LD for long diagonal, CD for short diagonal, L for strap and e for thickness.

[0080] The porous plate (such as a mesh plate) consists of a mesh having meshes whose long diagonal is 16 mm, the short diagonal is 8 mm, the strap is 1 mm and the thickness is 0.8 mm.

[0081] The short diagonal is measured between two mesh axes as shown in the figure.

[0082] To prevent the Asian hornet from exiting, on the axis of the short diagonal, the empty space, noted h, corresponding to the height of the mesh is less than 0.7 cm.

[0083] There Figure 5represents the elements of a kit for a truncated pyramid-shaped funnel according to the present invention, particularly well suited to the capture of Vespa velutina. In the context of the present invention, it has been found that the size of the thorax of Asian hornet queens Vespa velutina is very slightly smaller than the size of the thorax of European hornet queens Vespa crabro. It is thus possible to be selective in this regard.

[0084] Thus, this kit may comprise a base with a rectangular passage orifice (212) with a width of 7.21 mm (i.e. a passage limiting section of 7.21 mm) and a length of 20 mm. Truncated triangular pieces connected to each other by attachment means (I), make it possible to define a funnel. The attachment means may be of the male or female type as shown, making it possible to attach (e.g. by clips) to each other. The triangular piece may comprise male and / or female attachment means. The funnel may be inserted into a box to form a cage according to the present invention by attachment means (K). The box may comprise an attachment means complementary to the attachment (K), for example with a similar operation to the attachment (I). These truncated triangular pieces comprise a means for fixing the base, such as a notch (E).The base here is generally rectangular in shape, but can also be of another shape (triangular, pentagonal, hexagonal, etc.) depending on the number of truncated triangular pieces surrounding it. Preferably, the base is generally rectangular in shape, and requires 4 truncated triangular pieces to form the funnel (pyramidal truncated). The pores of the porous plate are here rectangles with rounded corners (here one whole side is rounded), whose length is 11 mm and whose width is 5 mm. Indeed, it has been noted that the exit of small insects is facilitated by such patterns (undercuts on the inner side on the porous plate and the cone with the edges of the rounded openings).

[0085] In the context of the present invention, a calibration to the hundredth of a millimeter (mm) was carried out for the passage orifice with tests carried out on 9 queens. Vespa velutinato check uniformity of the height of their thorax. In practice for 6 months (from mid-May 2017 to November 2017), two cages according to the present invention (one of which was photographed at the figure 6 ) put in place have made it possible to capture hornets Vespa velutinacurative (ie not the queens). The passage holes were identical: rectangular with a length of 20 mm and a width of 7.21 mm. The cages were configured so that the axis of the length (20 mm) of the holes was horizontal, and the axis of the width (7.21 mm) was vertical. The two traps were placed in the same honey bee apiary: one of them placed directly on a hive and the other at a distance. The type of bait used in the traps was honey-based (in the form of honeyed wax cappings from honey extractions for the boxes - possibility of using honey frames for the hives). 1062 Asian hornets (the equivalent of half a hive of these hornets) were thus captured with a noted selectivity of 99.7%. In fact, only one wasp queen and two first-generation European hornet workers were captured in addition to the hornets. Vespa velutina.The two European hornet-type workers (normally larger than Asian hornets) were accidentally caught (due to their reduced specific size compared to normal). However, such a catch proportion (0.2%) remains acceptable, even negligible, compared to the number of hornets. Captured Vespa velutina by the cage according to the present invention.

[0086] The same devices were installed in March 2018 for the entire following year: around twenty queens were quickly captured and a few workers subsequently, but much fewer than the previous year, demonstrating that preventive use focused on capturing queens in early spring. CLAUSES
