title: Evaluation of Three Commercial Backpack Sprayers with Aqualuer® 20-20 Against Caged Adult Aedes Aegypti.
abstract: Three commercially available backpack sprayers were evaluated with Aqualuer® 20-20 (20.6% permethrin, active ingredient; 20.6% piperonyl butoxide, technical) against caged adult Aedes aegypti in semifield trials in northeastern Florida. Two battery-powered sprayers, Birchmeier and Hudson, were compared with the standard hand-pump SOLO 425 sprayer, which is currently used in pest management operations. Physical characteristics, droplet analysis, and overall ease of use were documented. Multiple dilutions of the insecticide were also evaluated. The results indicated that the Birchmeier sprayer was the preferable machine in terms of its physical characteristics and operator use. There was no significant difference in percent mortality of the test mosquitoes between the sprayers. Multiple dilutions ranging from 1:9 to 1:1050 of the insecticide resulted in greater than 80% mean mortality.
