Title of the invention: Installation for capturing insects

[0001] 1. FIELD OF THE INVENTION

[0002] The present invention relates to an installation for capturing insects. TECHNOLOGICAL BACKGROUND

[0003] In the field of insect capture, a large number of diverse capture installations are known. WO 2022 / 034,085 describes for example an example of a trap based on the diffusion in the ambient air of an attractive composition for insects, which are thus attracted towards the trap and the source of attractive composition.

[0004] Although these traps provide great satisfaction, they nevertheless require significant maintenance to renew the attractant, the effectiveness of which is limited over time, and to remove the trapped insects, the excessive concentration of which can impair the effectiveness. Thus, while many known traps are suitable for domestic use, because an individual can set the trap for a limited period of time, for example a few hours, and regularly remove the caught insects, such domestic insect traps cannot be used effectively in an industrial or agricultural manner.

[0005] We are therefore looking for a way to reduce the maintenance associated with insect traps, so as to democratize their use. Summary of the invention

[0037] For this invention where gravity may play a role, the "Z" axis denotes the vertical axis, and the "X" and "Y" axes denote the axes of the horizontal plane. The "X" axis is arbitrarily defined as extending along a flat face of the installation of the embodiment of [Fig.l]. The terms "top" and "bottom", "upper" and "lower" are used to describe the arrangement relative to the vertical axis in the intended orientation of the product in use.

[0038] [Fig.l] schematically represents an installation 1 for capturing insects according to a first embodiment.

[0039] The installation 1 is suitable for capturing insects, such as for example insects harmful to agriculture. The installation 1 is suitable for capturing flying insects. However, the installation 1 can also be suitable for capturing non-flying insects. The insects concerned, for example insects harmful to agriculture, can for example be fruit flies, for example olive flies, or Bactrocera oleae, aphids, bugs or lepidoptera.

[0040] The installation 1 comprises a foot 2 resting on the ground 3. The ground is for example an exterior ground, in particular earth, for example a ground of a cultivated or arboriculture field.

[0041] In the example presented, the installation 1 is substantially in the form of a narrow, parallelepiped tower with a square base, with a height greater than its horizontal dimensions. However, other shapes are possible.

[0042] The installation 1 comprises a trapping compartment 4. The installation 1 also comprises a technical space 5. In the example presented, the technical space 5 comprises a technical compartment 6.

[0043] In the example presented, the trapping compartment 4 is arranged above the technical compartment 6. For example, the trapping compartment 5 overhangs the technical compartment 6. The trapping compartment 5 can thus be arranged at a height, relative to the ground, adapted to the insects to be captured, in particular in the case of flying insects.

[0044] As visible in [Fig.l], in this embodiment, the horizontal section of the trapping compartment 4 is identical to the horizontal section of the technical compartment 6.

[0045] As can be seen in more detail in [Fig. 2], the trapping compartment 4 comprises a peripheral wall 7. The peripheral wall 7 delimits a so-called “external” space 8 and an internal space. The peripheral wall 7 may be partially constituted by the technical compartment 6. In the example presented, the peripheral wall 7 is partially translucent. For example, the lower portion of the peripheral wall 7 is constituted by the top of the technical compartment 6, and the remainder of the peripheral wall is constituted by a translucent box or crate. In this example, the translucent box or crate has the shape of a rectangular parallelepiped, or even a cube. It is thus possible to provide a set of five translucent plates assembled together and fixed to the top of the technical compartment 6, the upper face of the latter forming the sixth side of the cube.However, any other suitable shape, for example pyramidal, partially spherical, or other, may be considered. The following description is given for the embodiment of Figures 1 or 2, but may be adapted according to the shape of the trapping compartment.

[0046] The trapping compartment 4 comprises at least one through opening, allowing communication between the interior and the exterior space 8. The through opening(s) make it possible to implement the following functions: diffusion of the attractive composition from the interior to the exterior space 8, and entry of the insects from the exterior space 8 to the interior. Depending on the embodiments, openings of different characteristics can be provided to implement these two functions. Alternatively, the openings are all identical to each other.

[0047] The trapping compartment 4 comprises a plurality of opening zones 9. In the example presented, all the opening zones 9 are identical to each other. According to the embodiment variants, the opening zones 9 could differ from each other.

[0048] An opening area 9 comprises a plurality of openings 10. In the example shown, an opening area 9 comprises 19x4 openings. However, as a variant, an opening area 9 could comprise more or fewer openings, for example 2n openings, 3n openings, 10n openings or 50n openings, where n is an integer between 1 and 20, for example n=2, n=6, n=8, ...

[0049] The peripheral wall 7 comprises a body 12 provided with a large opening closed by an inlet device 32 assembled to the body 12. The opening zone 9 is produced by the inlet device 32. The inlet device 32 comprises a base portion 11 in which the openings 10 are formed.

[0050] For example, the base portion 11 has the shape of a thin plate through which the openings 10 are formed. The body 12 of the peripheral wall 7 has a large opening in which the thin plate is assembled by any suitable means, removable or not, for example by interlocking, clipping, gluing or other. For example, the base portion 11 is assembled in a removable manner. Thus, different types of base portions 11 can be available, each adapted to a type of insect (different colors and / or openings), so as to make traps for different insects simply by replacing the base portions and the reservoir of attractive composition. For example, the base portion 11 has the shape of a disc. However, other sections are possible, such as a square, a rectangle, or the like.

[0051] According to one embodiment, the base portion 11 comprises an outer face 13 facing the outer space 8 and an inner face 14 opposite the outer face 13 and facing inwards. According to one embodiment, the outer face 13 is attractive to the insects to be trapped, and / or the inner face 14 is repellent to the insects to be trapped. For example, the outer face 13 is of a color attractive to the insects to be trapped, and / or the inner face 14 is of a color repellent to the insects to be trapped.

[0052] In the example shown where the peripheral wall 7 has several side panels, opening zones 9 are arranged on each side panel. This embodiment makes it possible to attract insects from all directions in space. Alternatively, one or more side panels could be devoid of opening zones 9, the installation then being oriented according to a preferred orientation. In the example shown, each side panel comprises two opening zones 9. Alternatively, a single opening zone 9 could be provided per side panel, or more than two opening zones 9 per side panel. In the example shown, the opening zones 9 are all arranged at the same height relative to the ground. Alternatively, opening zones 9 could be arranged at different heights relative to the ground.

[0053] In the example presented, the groups of openings 10 of the same opening zone 9 are equally distributed over the surface of the same opening zone 9. They are distributed in the following manner: a central group of openings, 6 groups of openings equally distributed on an inner circle centered on the central group of openings, and 12 groups of openings equally distributed on an outer circle centered on the central group of openings and whose radius is twice that of the inner circle, a radius passing through a group of openings of the outer circle forming the bisector of two adjacent rays passing through the groups of openings of the inner circle. Other arrangements are possible. For example, an opening zone 9 comprises a single group of openings 10.

[0054] As visible in [Fig.4], each group of openings 10 can itself be divided into a plurality of openings 10, for example by the implementation of one or more bars or a crosspiece 16.

[0055] Each opening 10 is of sufficient size for the passage of an insect to be trapped. The diameter of each opening 10 is for example greater than 1 millimeter (mm), greater than 2 mm, greater than 3 mm, or even greater than 5 mm. The diameter of each opening 10 is for example less than 2 centimeters (cm), less than 1.5 cm, less than 1 cm, or even less than 0.5 cm.

[0056] Thus, according to an exemplary embodiment, an opening zone 9 may comprise an outer disc 34 without crosspieces, comprising large openings and an inner disc 35 with crosspieces 16, assembled in such a way that the crosspieces of the inner disc restrict the size of the large openings of the red disc. The assembly is carried out in any suitable manner, for example by pressure, clipping, riveting, screwing, gluing or other. For example, the inner and outer discs are assembled to each other with the peripheral wall 7 interposed between them.

[0057] The installation 1 comprises a diffusion system 18 of attractive composition in the atmosphere.

[0058] The diffusion system 19 comprises a diffusion container 17 arranged in the trapping compartment 4, and receiving a composition attractive to the insects to be trapped. According to one embodiment, the attractive composition is a liquid attractive composition.

[0157] In an even more advantageous embodiment, the attractive composition comprises:

[0163] According to one embodiment, the attractive composition comprises 100 nanograms (ng) of the combination of (Z)-beta-ochnene and (E)-beta-ocimene, 100 nanograms of beta-caryophyllene, and 10 nanograms of decanal (or a non-zero multiple of this composition).

[0164] Alternatively, the attractive composition may be in solid, semi-liquid, pasty and / or viscous form.

[0165] As seen in [Fig.6], the diffusion container 17 comprises a cup adapted to contain a volume of attractive composition. The diffusion container may have any suitable shape, such as partially spherical, frustoconical, pyramidal or other.

[0166] The diffusion system 18 also comprises a fan 19 arranged in the trapping compartment 4. The fan 19 is arranged above the diffusion container 17. The actuation of the fan 19 generates a flow of air which is charged with attractive composition then leaves the trapping compartment 4 via the openings 10.

[0167] The technical compartment 6 is in the form of a cabinet locked by a locking system 20. Thus, only personnel with a key (mechanical or digital) can access the components inside the technical compartment.

[0168] The technical compartment 6 houses a tank 21 of attractive composition. The technical compartment 6 comprises a supply system 22 adapted to move attractive composition from the reservoir 21 to the diffusion container 17. The supply system 22 comprises for example a pump 23 and a fluid connection 24 connecting the reservoir 21 of attractive composition and the diffusion container 17.

[0169] The technical compartment 6 also houses a drainage system 25. The drainage system 25 comprises a drainage tank 26 and a fluid connection 27 connecting the diffusion container 17 and the drainage tank 26. The fluid connection 27 may comprise a siphon.

[0170] The technical compartment 6 also houses a valve or valve system 28 selectively authorizing or prohibiting the passage of fluid from the reservoir 21 of attractive composition to the diffusion container 17 and the passage of fluid from the diffusion container 17 to the drain tank 26.

[0171] The technical compartment 6 also houses an energy reserve, of the battery 29 type or other, supplying energy to the system components that need it.

[0172] The technical compartment 6 also houses a controller 30 adapted to control the fluid circulation, according to predetermined rules. In particular, the controller 30 is programmed to open the valve and control the pump 23 to generate the flow of a quantity of liquid composition from the attractive composition reservoir 21 to the diffusion container 17. The controller 30 is programmed to open the valve to generate the flow of a quantity of liquid composition from the diffusion container 17 to the drain tank 26. The controlled valve and the associated connections thus form a drain device. The controller 30 is also programmed to selectively actuate or not the fan 19.

[0173] According to one embodiment, the installation 1 for capturing insects comprises a solar panel 33. The solar panel is for example arranged above the trapping compartment 4. [Fig.l] shows an exemplary embodiment where the installation 1 for capturing insects comprises a mast 31 supporting the solar panel (not shown). The captured energy is converted into electricity, and transmitted through the mast to the battery 29. The technical compartment 6 also houses the control electronics of the solar panel. For example, the mast 31 passes through the trapping compartment 4. Alternatively, it could pass along the trapping compartment 4 outside of it.

[0174] The system just described operates as follows.

[0175] Initially, the installation 1 for capturing insects as described above is installed at its place of operation. According to one example, the installation is configured for capturing olive flies.

[0176] Installation 1 for capturing insects is energy-autonomous, by means of the solar panel, and does not need to be connected to the mains to operate. Alternatively or in addition, the installation could operate autonomously on battery power.

[0177] The attractive composition tank 21 is full. The drain tank 26 is empty.

[0178] The controller 30 controls the movement of a quantity of attractive composition from the attractive composition reservoir 21 to the diffusion container 17. Then the hydraulic circuit is stopped.

[0179] The controller 30 controls the fan 19.

[0180] The fan 19 generates an air flow which diffuses the attractive composition from the inside of the trapping compartment 4 towards the outside, through the openings 10.

[0181] Olive flies are attracted to the insect trapping facility 1 by the attractive composition. They are attracted and enter inside the trapping compartment 4 through the openings 10.

[0182] Few insects come out through the openings 10, because they are attracted by the attractive composition, the inner face 14 is less attractive than the inner face, for example neutral in terms of attractiveness for insects, or even repellent, and the openings are small and frustoconical in the direction from the outside to the inside.

[0183] The insects die inside the trapping compartment 4. For example, they drown in the liquid composition contained in the diffusion container 17.

[0184] Alternatively or additionally, the insect capture facility comprises alternative devices for killing the insects, such as for example by drying, suction, gluing, electrocution or starvation. The dead insects then fall into the diffusion container 17.

[0185] The controller 30 controls the emptying of the diffusion container 17. This involves, for example, opening the valve 28, so that the contents of the diffusion container, comprising the remaining attractive composition and the dead insects, flow into the emptying tank 26, until the diffusion container 17 is empty.

[0186] The cycle just described above typically lasts between one hour and twelve hours, depending on the lifetime of the attractive composition and the quantity used. The controller is programmed to repeat the above cycle. This repetition can be implemented via a predetermined rule, for example with a fixed given frequency, and / or taking into account the circadian cycle, or other.

[0187] The above cycle can be repeated until the composition tank at tractive has a remaining volume of attractive composition less than a predetermined threshold, or that the drain tank has a volume greater than a predetermined threshold.

[0188] An operator can then carry out maintenance, and replace the two tanks in question with a full attractive composition tank and an empty drain tank.

[0189] Alternatively, pump 23, or an additional dedicated pump (not shown) can be used for draining.

[0190] According to an alternative embodiment, the technical compartment 6 can be arranged above the trapping compartment 4. Such an installation 1 can be used for capturing insects closer to the ground.

[0191] According to an alternative embodiment, as shown in [Fig. 7], the technical space 5 comprises a plurality of technical compartments, and the different components received in the technical space 5 are distributed functionally in the different technical compartments. For example, as shown in [Fig. 7], the tower shape is retained, and the trapping compartment 4 is arranged between an upper technical compartment 6a and a lower technical compartment 6b. According to one example, the upper technical compartment 6a houses the attractive composition reservoir 21. In this embodiment, a pump is not necessarily used, the attractive composition 21 being capable of flowing under the effect of gravity from the attractive composition reservoir 21 to the diffusion container 17.

[0192] According to another embodiment, as shown in [Fig.8], the fan 19 is also used to suck the insects into the trapping compartment 4. In this exemplary embodiment, the fan 19 may for example be arranged under the diffusion container 17, and openings 10 in the vicinity of the fan 19 (above, at the level and / or below), so that the fan 19 generates a flow of air loaded with attractive composition towards these lower openings. The attractive composition could be dispensed in solid form in this embodiment. The trapping compartment 4 also has openings 10 above the diffusion container 17, so that the insects attracted near the installation 1 by the attractive composition are sucked inside through these upper openings.
