Definitions

  • the present invention relates to an apparatus for trapping insects, such as fruit flies, and its use in methods of monitoring and/or controlling and/or eradicating insect infestations and monitoring for the presence of insects such as fruit flies.
  • Insecticide cover sprays using organophosphates such as dimethoate and lebaycid are systemic and thus kill eggs and larvae within fruit. Their use in Australia is restricted and a complete ban is expected to be imposed by APVMA (Australian Pesticides and Veterinary Medicines Authority).
  • Protein bait sprays where substances such as yeast proteins are combined with an organophosphate insecticide such as malathion and are "spot" sprayed at the rate of 10 L/hectare. This method is successful in many crops - - but difficult to apply to some field vegetable crops, breaks down under heavy rainfall conditions and is less effective in tropical countries. It cannot be used in some countries where fruit crops are susceptible to attack during the summer monsoon period, e.g. Bhutan citrus.
  • the protein baits are applied to crops as described above while the male lure (Cue-Lure® or methyl eugenol) is soaked in an absorbent material with an insecticide added, and these small “blocks” are attached to trees (host or non- host) at approximately 300-400 per km 2 .
  • This approach is often expanded over large areas under the concept of Pest Free Areas or Areas of Low Pest

  • the host plant is the "centre of activity" for a localised fruit fly population. 2.
  • the host plant with ripening fruit attracts sexually mature male flies and sexually immature female fruit flies.
  • the most effective current traps include lures that attract only male fruit flies. This leaves the females able to mate with untrapped males and therefore they are still able to oviposit in ripening fruit and vegetables. Damage to crops still occurs.
  • the present invention provides an insect trap comprising a plurality of members joined at a central region and extending outwardly therefrom to form a structure approximating an open spheroid, the members providing a surface wherein at least 25% of the total surface is coated with an insect trapping adhesive.

  • Providing an open spheroid not only enables the trap to be more easily and - - economically manufactured, but also provides a relatively large surface area on which insects can land and be trapped or killed.
  • the members comprise at least four extensions that extend from a central region of the structure wherein the four extensions extend radially outwardly of the central region to form the structure approximating a spheroid, and namely a structure occupying a volume akin to a spheroid.
  • there may be more than four extensions extending in a radial direction from the central region including 6, 8, 10 or 12 extensions, or an odd number of extensions, where the more extensions there are extending from the central region, the closer the structure will approach a spherical or spheroid shape.
  • the members may themselves form each extension, or one member may comprise two or more extensions, for example, in the embodiment where the members are discs, as described below, each disc comprises two extensions.
