Container mosquitoes are prime public and veterinary health threats. They are the primary vectors of mosquito-borne viruses such as chikungunya, dengue, and zika which can cause illness among the humans. Stagnant water collected in small, squalid spaces form the habitat of these container mosquitoes. Conventional control methods focus on treating or eliminating larval habitats. However, the limitations of traditional insecticide-based strategies, particularly the development of insecticide resistance, have resulted in significant efforts to develop alternative eco-friendly methods.Rutgers scientists have developed a special pyriproxyfen autodissemination station that topically contaminates oviposition-seeking mosquitoes which then carry toxic levels of insecticide to untreated larval habitats in urban environments. A prototype of this technology is constructed using biodegradable materials such as peat moss, egg cartons, rice hulls, newspaper, straw, natural polymers, and water-soluble binders. The shape and features attract urban mosquitoes, yet do not permit egg laying.As an insect-growth regulator, pyriproxyfen is virtually nontoxic to birds and mammals. The ‘bait’ approach inherent to autodissemination is precisely targeted and therefore environmentally- friendlier than the broadcast spray of adulticides normally used.
