Title of the invention: Insect capture device
[0001] 1. SCOPE 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 devices are known. WO 2022 / 034,085 describes, for example, a trap based on the diffusion in the ambient air of an insect-attractive composition, which is thus attracted to the trap and the source of the attractive composition.
[0004] Although these traps provide significant satisfaction, they nevertheless require substantial maintenance to replenish the attractant, whose effectiveness is limited over time, and to remove the trapped insects, whose high concentration can impair their effectiveness. Thus, while many known traps are suitable for domestic use, since an individual can activate the trap for a limited period, for example, a few hours, and regularly remove the trapped insects, such domestic insect traps cannot be used effectively on an industrial or agricultural scale.
[0005] We are therefore looking for a way to reduce the maintenance associated with insect traps, in order to democratize their use. Summary of the invention

[0037] For this invention, in which gravity may play a role, the vertical axis is designated by the "Z" axis, and the horizontal plane axes by the "X" and "Y" axes. The "X" axis is arbitrarily defined as extending along a flat face of the installation of the embodiment of [Fig. 1]. The terms "top" and "bottom," "upper" and "lower" are used to describe the arrangement with respect to the vertical axis in the intended orientation of the product.
[0038] Fig. 1 schematically represents an installation 1 for the capture of insects according to a first embodiment.
[0039] Installation 1 is adapted for capturing insects, such as, for example, insects harmful to agriculture. Installation 1 is adapted for capturing flying insects. However, Installation 1 can also be adapted for capturing non-flying insects. The insects concerned, for example, insects harmful to agriculture, may include fruit flies, such as olive fruit flies (Bactrocera oleae), aphids, stink bugs, or Lepidoptera.
[0040] The installation 1 includes a foot 2 resting on the ground 3. The ground is for example an outdoor ground, in particular earth, for example the ground of a field of cultivation or arboriculture.
[0041] In the example shown, the installation 1 is essentially in the form of a narrow, parallelepiped-shaped tower with a square base, whose height is greater than its horizontal dimensions. However, other shapes are possible.
[0042] Installation 1 includes a trapping compartment 4. Installation 1 also includes a technical space 5. In the example shown, the technical space 5 includes a technical compartment 6.
[0043] In the example shown, the trapping compartment 4 is positioned above the technical compartment 6. For example, the trapping compartment 5 overhangs the technical compartment 6. The trapping compartment 5 can thus be positioned at a height, relative to the ground, suitable for the insects to be captured, particularly in the case of flying insects.
[0044] As can be seen in [Fig.1], in this embodiment, the horizontal section of the trapping compartment 4 is identical to the horizontal section of the technical compartment 6.
[0045] As shown in more detail in [Fig. 2], the trapping compartment 4 comprises a peripheral wall 7. The peripheral wall 7 delimits an "exterior" space 8 and an interior space. The peripheral wall 7 may be partially formed by the technical compartment 6. In the example shown, the peripheral wall 7 is partially translucent. For example, the lower portion of the peripheral wall 7 is formed by the top of the technical compartment 6, and the remainder of the peripheral wall is formed by a translucent box or container. In this example, the translucent box or container is rectangular in shape, or even cube-shaped. Thus, a set of five translucent plates assembled together and fixed to the top of the technical compartment 6 can be provided, the upper face of which forms the sixth side of the cube.However, any other suitable shape can be considered, for example pyramidal, partially spherical, or otherwise. The following description is given for the embodiment shown in Figures 1 or 2, but can be adapted according to the shape of the trapping compartment.
[0046] The trapping compartment 4 has at least one through-opening, allowing communication between the interior and the exterior space 8. The through-opening(s) enable the following functions: diffusion of the attractant composition from the interior to the exterior space 8, and entry of insects from the exterior space 8 into the interior. Depending on the embodiment, openings with different characteristics may be provided to implement these two functions. Alternatively, the openings are all identical.
[0047] The trapping compartment 4 comprises a plurality of opening zones 9. In the example shown, all the opening zones 9 are identical to each other. According to alternative embodiments, the opening zones 9 could differ from each other.
[0048] An opening zone 9 comprises a plurality of openings 10. In the example shown, an opening zone 9 comprises 19x4 openings. However, alternatively, an opening zone 9 could comprise more or fewer openings, for example 2n openings, 3n openings, 1n 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 having a large opening closed by an inlet device 32 assembled to the body 12. The opening area 9 is made 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 into which the thin plate is assembled by any suitable means, removable or not, for example by interlocking, clipping, gluing, or otherwise. For example, the base portion 11 is assembled in a removable manner. Thus, different types of base portions 11 can be used, each adapted to a type of insect (different colors and / or openings), so as to create traps for different insects simply by replacing the base portions and the reservoir of attractant composition. For example, the base portion 11 has the shape of a disc. However, other cross-sections are possible, such as a square, a rectangle, or otherwise.
[0051] In one embodiment, the base portion 11 comprises an outer face 13 facing outwards from the outer space 8 and an inner face 14 opposite the outer face 13 and facing inwards. In 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 a color attractive to the insects to be trapped, and / or the inner face 14 is a color repellent to the insects to be trapped.
[0052] In the example shown, where the peripheral wall 7 has several lateral panels, opening zones 9 are arranged on each lateral panel. This embodiment makes it possible to attract insects from all directions of the space. Alternatively, one or more lateral panels could be without opening zones 9, the installation then being oriented according to a preferred orientation. In the example shown, each lateral panel includes two opening zones 9. Alternatively, one could provide a single opening zone 9 per lateral panel, or more than two opening zones 9 per lateral 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 shown, 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 as follows: 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 group of central openings whose radius is twice that of the inner circle, a radius passing through a group of openings on the outer circle forming the bisector of two adjacent radii passing through groups of openings on the inner circle. Other arrangements are possible. For example, an area of opening 9 comprises a single group of openings 10.
[0054] As can be seen 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 crossbar 16.
[0055] Each opening 10 is large enough 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 one embodiment, an opening area 9 may comprise an outer disc 34 without crossbars, having large openings, and an inner disc 35 with crossbars 16, assembled so that the crossbars 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 pressing, clipping, riveting, screwing, gluing, or otherwise. For example, the inner and outer discs are assembled to each other with the peripheral wall 7 interposed between them.
[0057] Installation 1 includes a diffusion system 18 of attractive composition in the atmosphere.
[0058] The diffusion system 19 comprises a diffusion container 17 disposed in the trapping compartment 4, and receiving an attractant composition for the insects to be trapped. In one embodiment, the attractant composition is a liquid attractant composition. In one example embodiment, the liquid attractant composition is an attractant composition for the olive fruit fly. In one embodiment, the attractant composition comprises (Z)-beta-ocimene, (E)-beta-ocimene, beta-caryophyllene, and decanal. In one embodiment, (Z)-beta-ocimene, (E)-beta-ocimene, beta-caryophyllene, and decanal are the only active substances in the attractant composition.

[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 hold 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 includes a fan 19 disposed in the trapping compartment 4. The fan 19 is disposed above the diffusion container 17. The actuation of the fan 19 generates an airflow which becomes charged with attractive composition and then exits the trapping compartment 4 through 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 reservoir 21 of attractive composition. The technical compartment 6 includes a supply system 22 adapted to move the attractive composition from the reservoir 21 to the diffusion container 17. The supply system 22 includes, 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 includes a drainage tank 26 and a fluid connection 27 connecting the diffusion container 17 and the drainage tank 26. The fluid connection 27 may include a siphon.
[0170] The technical compartment 6 also houses a valve or valve system 28 that selectively permits or prohibits the passage of fluid from the attractive composition reservoir 21 to the diffusion container 17 and the passage of fluid from the diffusion container 17 to the drain reservoir 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 require 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 vessel 17. The controller 30 is programmed to open the valve to generate the flow of a quantity of liquid composition from the diffusion vessel 17 to the drain reservoir 26. The controlled valve and associated connections thus form a drain device. The controller 30 is also programmed to selectively activate or deactivate the fan 19.
[0173] According to one embodiment, the insect-capturing installation 1 includes a solar panel 33. The solar panel is, for example, positioned above the trapping compartment 4. Figure 1 shows an example of an embodiment where the insect-capturing installation 1 includes 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 solar panel's control electronics. For example, the mast 31 passes through the compartment of trapping 4. Alternatively, it could pass along trapping compartment 4 outside of it.
[0174] The system just described works as follows.
[0175] Initially, the insect capture installation 1, as described above, is installed at its operating location. According to one example, the installation is configured for the capture of olive flies.
[0176] The insect-capturing device 1 is energy self-sufficient, using a solar panel, and does not require a mains connection to operate. Alternatively or in addition, the device could operate autonomously on battery power.
[0177] The attractive composition tank 21 is full. The drain tank 26 is empty.
[0178] The controller 30 commands 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 airflow which diffuses the attractive composition from inside the trapping compartment 4 to the outside, through the openings 10.
[0181] Olive flies are attracted to the insect capture installation 1 by the attractive composition. They are attracted and enter the trapping compartment 4 through the openings 10.
[0182] Few insects emerge from 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 to insects, or even repellent, and the openings are small and truncated conical 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 in addition, the insect-capture installation includes alternative devices for killing insects, such as, for example, desiccation, 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, including the remaining attractive composition and dead insects, flow into the drain tank 26, until the diffusion container 17 is empty.
[0186] The cycle described above typically lasts between one and twelve hours, depending on the lifespan of the attractant 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 by taking into account the circadian rhythm, or other factors.
[0187] The above cycle can be repeated until the attractive composition tank has a remaining volume of attractive composition less than a predetermined threshold, or 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 one 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 one embodiment, as shown in [Fig. 7], the technical space 5 comprises a plurality of technical compartments, and the various components received in the technical space 5 are functionally distributed among 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. In one example, the upper technical compartment 6a houses the attractive composition reservoir 21. In this embodiment, a pump is not necessarily used, as the attractive composition 21 can flow by 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 draw insects into the trapping compartment 4. In this embodiment, the fan 19 can, for example, be positioned below the diffusion container 17, and openings 10 are located near the fan 19 (above, at the same level as, and / or below it), such that the fan 19 generates a flow of air laden with the attractant composition towards these lower openings. The attractant 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 insects attracted to the vicinity of the device 1 by the attractant composition are drawn inside through these upper openings.
