Interpretive Summary:

Technical Abstract: Barrier spraying is an emerging practice used to control mosquito populations and vector-borne diseases. Talstar (a.i. bifenthrin), a pyrethroid, was the pesticide chosen for this study, because of its environmental persistence and efficacy against mosquitoes. In two separate test plots near Stuttgart, AR, Talstar was applied to different areas at 0.11 and 0.22 lb a.i./acre. The first plot called the mini-plot study used potted wax myrtle (Myrica cerifera) plants placed in clusters. The second plot was called the small plot study utilized a 0.1 acre woodland for pesticide application. After spraying with a Dyna-Fog Twister XL, MODEL 3950, Series 2, motorized knapsack cold fog ULV sprayer, leaves were collected at 1, 7, 14, and 21 days and shipped to CMAVE for chemical analysis (GC/MS) and tarsal contact assays with Ochlerotatus taeniorhynchus and Anopheles quadrimaculatus mosquitoes. In each study plot, 2 Coleman MD-2500 mosquito traps were added to collect mosquitoes for population assessment and barrier treatment performance. These traps use propane to create CO2 and are also baited with a lure containing 1-octen-3-ol. Collected mosquitoes were frozen and shipped to CMAVE for counting and species determination. Data collected will determine the chemical residue and biological effectiveness of using bifenthrin as a barrier spray.
