Bovine blood inoculated with bacteria isolated from screwworm [Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae)]-infested animal wounds was tested as an attractant for oviposition for gravid screwworms. Eight species of gram-negative coliform (Enterobacteriaceae) bacteria mixed with bovine blood singly or all species combined and incubated for various times produced volatiles that attracted gravid flies in a cage bioassay in varying numbers. In 15-min duration tests, volatiles from five species of bacteria (Klebsiella oxytoca, Proteus mirabilis, Proteus vulgaris, Providencia rettgeri, and Providencia stuartii) attracted more females than volatiles of the three species (Enterobacter cloacae, Enterobacter …

Catches of mosquitoes and sand flies in CO2 traps baited with three different lures and an unbaited control were compared. The lures examined were carbon dioxide, carbon dioxide plus l-octen-3-ol, and carbon dioxide plus human hair in ethanol. Studies using a 4 x 4 Latin square design, with 3 sets of 4 consecutive trap nights, were conducted between August 6 and September 10, 2007. The study site was the Bahrif Village, Aswan, Egypt. This location had high percentage of Phlebotomus papatasi in sand fly populations, and the low incidence of human cases of leishmaniasis. There were 2,152 sand flies …

Chemical lures can enhance the ability of traps to collect mosquitoes, selectively target species for capture, and provide a realistic assessment of the species and host-equivalent numbers of mosquitoes present in the local area. One approach to the development of chemical lures is to manufacture blends that comprise odors released in human emanations. These blends need to be safe for use in the environment, desirable from an economic standpoint, and transportable to the field for use in traps. In this report, we compared the attraction of mosquitoes to various chemicals, blends, and odors from humans. Noncompetitive (single-treatment) bioassays established that …
Traps And Trapping Techniques For Adult Mosquito Control, Daniel L. Kline
Traps And Trapping Techniques For Adult Mosquito Control, Daniel L. Kline
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
An overview is presented of the recent advancements in research activities conducted to evaluate mosquito traps. insecticide-impregnated targets baited with combinations of attractants, and strategies for using mass trapping techniques for adult mosquito population management. Technologies that use semiochemicals (attractants). traps and targets. and mass trapping are relatively new for management of adult mosquito populations. To date. emphasis has been placed primarily on developing barriers of attractant-baited and insecticide-impregnated targets. The most successful continuous use of this type of technology has been at Stevens' Landing. Collier County. Florida, Recently. commercially available traps have been evaluated for their ability to reduce …
