Definitions

  • This invention relates to insect traps, such as insect traps that can be used outdoors, e.g. in orchards, vineyards and the like, to attract and kill flying insects.
  • insects often need to be attracted and killed in different ways, depending on the types of attractants that are effective in attracting the insects, typical flight paths of the insects, their landing habits and methods of exposing the insects to toxins, e.g. causing the insects to ingest toxins.
  • attractants that are effective in attracting the insects
  • typical flight paths of the insects their landing habits and methods of exposing the insects to toxins, e.g. causing the insects to ingest toxins.
  • different insect trap constructions are created for different insects or groups of insects and the need to manufacture different types of traps for different insects further increases costs.
  • Attractants typically need to evaporate or sublimate to be effective and thus need to be housed in manners that are protected from the elements, but are exposed to atmosphere. This is typically achieved by constructing costly structures such as rigid housings that are supported on posts or other supports.
  • many insect traps are also labour intensive and thus expensive in terms of labour cost, because the installation, operation, maintenance, retrieval, etc. of the traps is complex and/or time consuming. This holds true in particular, in cases where insect traps need to be attached to plants or other supports in cumbersome attachment methods.
  • the present invention seeks to provide insect traps that are effective in attracting and killing insects and are still cost effective and environmentally friendly.

  • traps 10.1 are selected that contain one or more chemical attractant and one or more toxin that target an insect or selection of insects that need to be controlled, e.g. fruit flies and/or codling moths.
  • the traps are placed in position, e.g. they are attached to branches in an orchard, with their loops 20 extending around branches of trees, so that they are freely suspended below the branches, with their openings 14 facing down.
  • the downward orientation of the openings 14 limits the exposure of the composition 32 to the elements, such as direct sunlight and rain.
  • the flexible attachment of the trap 10 to the trees via the loop 20 and the conical shape of the shell 12 causes the shell to be directed automatically if exposed to wind so that its apex 18 faces towards the wind.
  • its opening 14 faces away from the approaching wind, which may carry rain or the like.
  • the shell automatically directs itself when exposed to adverse weather conditions to protect the opening 14 and cavity 16 from the elements. This inhibits the adverse effects that the elements may have on the composition 32 and prolongs the useful life of the composition.
  • the chemical attractant in the composition 32 attracts insects, especially flying insects and this attraction is enhanced by the colour of the outer film 28 of the shell, which is preferably yellow.
  • the attracted insect enters the opening 14 and contacts the composition 32, which contains the toxin and kills the insect.
  • the second embodiment of the insect trap 10.2 also includes a conical shell 12, like that of the first embodiment, but which comprises of only an outer film 28 and no liner.
  • a substrate element in the form of an inner cone 34 is made from a film similar to that of the shell and is spaced below the outer shell 12 with the same orientation and with the apex 36 of the inner cone extending into the cavity 16.
  • a liner 30, similar to that described above in relation to the first embodiment of an insect trap, is attached to the outside (top) of inner cone 34, facing the cavity 16.
  • the shell 12 and inner cone 34 are kept in their spaced-apart configuration by a spacer 38.
  • spacer 38 many configurations of such a spacer 38 can be used, but in the illustrated embodiment, the spacer extends through apertures in the apices of the shell 12 and inner cone 34 and caries two beads 24, each immediately below the aperture and larger than the aperture.
  • a hook 40 is formed at the top of the spacer, which can receive a loop 20 or any other suitable support means for the trap 10.2.
  • the trap 10.2 functions very similarly to the trap 10.1 described above, but with the configuration of the trap 10.2, the lower part of the inner cone 34 and thus the lower part of the liner 30, carrying the chemical toxin, protrudes below the shell 12 and cavity 16, so that flying insects that are attracted by the chemical toxin, land on the liner 30 and are exposed to the chemical toxin in the composition 32 applied to the liner.

  • the third embodiment of an insect trap 10.3 is made from a flat sheet of material that is folded so that central parts of the sheet form two generally parallel and adjacent upright walls 42 and so that peripheral parts of the sheet each extend at an angle relative to the walls, to form a shell 12, with a cavity 16 below the shell.
  • the folds of the sheet where each wall 42 is connected to the shell 12 are attached together with an adhesive 44 and a hook 40, loop or like support means is also attached to the trap 10.3 in the same area.
  • a chemical attractant composition 46 is provided inside the cavity 16, preferably on the underside of the intersection of the shell 12 and wall 42 on each side of the trap 10.3. This location of the chemical attractant lures insects deeper towards the cavity 16.
  • a liner 30 is provided on the side of each wall 42 that faces outwards and a chemical toxin is applied to the liner. Insects are lured to the cavity 16 by the chemical attractant and land on the upright surfaces of the liners 30, where they are exposed to the chemical toxin.
  • the trap 10.3 is preferably shaped and dimensioned so that the liners 30 carrying the chemical toxin are protected from the elements below the shell 12, but partly extend below the cavity 16, so that they are visible to approaching insects.
  • the trap 10.3 is believed to be particularly effective against flying insects that prefer landing on upright surfaces rather than on an inverted or upwardly-facing surfaces and the arrangement of the trap 10.3 is believed to be particularly effective against white flies.
  • a the fourth embodiment of the insect trap 10.4 includes a conical outer shell 12 with an outer film 28 and inner liner 30.1 , similar to those of the first embodiment and includes a substrate element in the form of an inner cone 34 with an outer liner 30.2, similar to those of the second embodiment.
  • a carrier composition 32.1 with a chemical attractant is applied to the liner 30.1 inside the cavity 16 of the outer shell 12 and a carrier composition 32.2 with a chemical toxin is applied to the outer liner 30.2 of the inner cone 34.
  • the outer shell 12 and inner cone 34 are kept spaced apart by a spacer 38 similar to that of the second embodiment, with a hook formation 40 at its top.
  • This configuration is believed to be particularly effective in providing protection against the elements, for the composition 32.1 containing the chemical attractant, as described above, while providing a landing surface with the chemical toxin, on the outside of the cone 34. Insects attracted by the attractant inside the shell 12 are thus lured towards the cavity 16 and can land on the outside of the cone 34 and be exposed to the chemical toxin. This embodiment is thus believed to be effective in the control of pests that prefer landing on an inclined surface.
  • the attachment means in the fourth embodiment of the insect trap 10.4 includes a clip 48 (instead of a loop 20) that is made from resilient polymeric sheet material, with a profile that defines a recess 50, with two purchase formations in the form of hook formations 52 on opposing sides of an opening 54 of the recess.
  • the hook formations 54 are slanted towards the inside of the recess 50, which allows the clip 48 to be attached very quickly and easily to a branch 56 by clipping the branch past the hook formations from the outside of the clip 48, towards the recess 50, to hold the branch captive inside the cavity.
  • the clip 48 can be made from un-stabilised material to ensure its bio degradability and can be produced at extremely low cost. Instead of the hook formations 52, the clip 48 could include other purchase formations, such as rows of teeth, tapering surfaces, or the like.
  • the respective carrier compositions 32 used for the attractant and toxin can be selected to improve the efficacy and useful life of these respective compositions.
  • the attractant compositions are required to evaporate/sublimate more easily and are provided in locations that are better protected against the elements.
  • the carrier compositions for the toxins need to be more robust against the elements, because they are more exposed and they are more exposed to contact with insects. The physical contact with insects also requires the carrier compositions for the toxins to be more robust against physical damage and obviates the need for these compositions to allow the toxins to evaporate or sublimate.
  • the traps 10 are made of very inexpensive materials and their use is very simple, and accordingly, they allow for very cost-effective control of pests, especially flying insects in orchards or vineyards.
  • the traps 10 are made of bio-degradable materials and accordingly, they need not necessarily be removed from the orchards after use and/or if a trap is inadvertently removed from a tree, it is eventually absorbed by the environment and does not cause litter with a practically indefinite life span, as is the case with many existing insect traps.
