Definitions

  • the present disclosure generally relates to insect trapping cartridges and devices.
  • pest control devices have been employed to trap insects and other pests. With recent outbreaks of various diseases, infections, and other health risks that are spread by insects, the need for pest control devices has only increased. Such pest control devices typically employ an attraction mechanism for luring pests to the pest control device. Example attraction mechanisms include baits such as food, light, heat, pheromones, or other odorous materials found attractive by the pest. Some pest control devices have historically included an immobilization mechanism to prevent the pest from exiting the pest control device.
  • One type of immobilization mechanism used is a substrate such as a board, paper, or other medium having a surface coated with an adhesive. Pests attracted to the pest control device or incidentally coming into contact with the adhesive become trapped by adhesion.
  • mosquitoes can be particularly dangerous.
  • Certain species of mosquitoes are known carriers of a number of diseases, including malaria, dengue fever, yellow fever, the west nile vims and the zika virus. Of these diseases, malaria has been described by some as the“most prevalent and most pernicious disease of humans”. White, N., Antimalarial Drug Resistance, The Journal of Clinical Investigation, Vol. 113, no. 8 (2004). As of 2010, the World Health Organization estimated that 219 million cases of malaria and 660,000 deaths occurred.
  • mosquito species such as Aedes Aegypti, Aedes Albopictus, Aedes Canadensis, Anopheles Gambiae, Anopheles Fenustus, Culex Annulirotris, Culex Annulus and Culex Pipiens, are believed to be carriers of human disease.
  • Heat is a known attractant for mosquitoes. See, e.g., Maekawa et ak, The role of proboscis of the malaria vector mosquito Anopheles stephensi in host-seeking behavior, Parasites and Vectors, 4:10 (2011). Greppi et al. observed that“mosquitoes were strongly attracted to a target when heated above ambient, but only up to ⁇ 50°C. When it got hotter, this attraction declined strongly.” Greppi et al., Some like it hot, but not too hot, eLife 4:el2838 (2015). See, also, Corfas et al., The cation channel TRPA1 tunes mosquito thermotaxis to host temperatures, eLife 4:ell750 (2015).
  • Mosquitoes and other insects can also be attracted to light sources. See, e.g., Burkett et al., Laboratory evaluation of colored light as an attractant for female aedes agypti, aedes albopictus, anopheles quadrimaculatus and culex nigripalpus, The Florida Entomologist, Vol. 88, No. 4 (2005).
  • Insect trapping devices that combine an adhesive for trapping insects together with light and heat are known, some examples being described in PCT patent application publication WO 2015/164,849.
  • an insect trapping device that provides improved techniques for attracting insects, particularly mosquitoes, to the device.
  • an insect trapping device that provides improved techniques for the evaporation and dispersal of an insect attractant composition, particularly for mosquitoes, from a device.
  • an insect trapping device that combines one or more of the foregoing advantages with techniques that improve the number of insects attracted to the device. While numerous opportunities for improvement are described above, it will be appreciated that the disclosure hereafter is not limited to devices that provide any or all such improvements.

  • the front surface 126 may define one or more openings 132 for receiving a flying, walking or crawling insect such that they can come in contact with the front face 154 of the adhesive portion 152 of the divider 150. While FIGS. 1-2 depict one example arrangement of openings 132, it is to be appreciated that the size, shape, arrangement, and number of the one or more openings 132 can vary.

Moreover, the orientation of the exposed surface area 178 to the divider 150 can also beneficially reduce the offset distance between the exposed surface area 178 and the adhesive portion 152, which can serve to increase the capture and retention of insects by the insect trapping device 100.

Without intending to be bound by any theory, it is believed that the mosquitos are attracted to the parts of the insect trapping device 100 where the insect attracting composition 176 is exiting (i.e., the top openings 180), but that due to the physical size of mosquitos, openings having widths of less than about 3 mm are not conducive for traversal.
