Technical Abstract: Protection of deployed military personnel using conventional methods is often not practical. Objectives were: 1) assess perimeter barrier treatments in resting habitats, 2) develop small plot pesticide screening protocols, and 3) compare standard backpack versus electrostatic sprayers. Miniplots (10 ft x 10 ft) consisting of wax myrtles (Myrica cerifera) were established in Florida and Arkansas. Bifenthrin, (0.11 and 0.22 lb a.i. per acre) was applied. Efficacy was determined by trapping, landing counts, bioassays and chemical residue analysis. Coleman MD-2500® mosquito traps were operated in mini-plots to collect mosquitoes. Bioassays were conducted with leaves from the plants in the mini-plots. Additional plants were used for collecting leaves for chemical residue analysis. Bioassays and residue analysis were conducted pretreatment, day of treatment, and weekly post-treatment until 24 hr mortality was less than 10% in the bioassays. Gainesville cage studies used laboratory reared mosquitoes (Ochlerotatus taeniorhynchus and Aedes aegypti); in Arkansas natural populations of Anopheles quadrimaculatus and Psorophora columbiae, produced in large numbers in rice-fields were used. Bifenthrin was also applied (0.22 lb a.i./acre) to perimeters (8 ft wide x 6 ft high) of field plots (0.1 acre) near rice-fields in Arkansas. Efficacy was determined in the same manner as for the mini-plots.
