United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Freeze-dried, granular sugar baits containing boric acid as the toxicant were evaluated against house flies, Musca domestica L., in two bioassays with toxicant dose ranges of 3, 5, 7, 8, and 12%, and 3, 5, 9, 17, and 33% boric acid, respectively, calculated and expressed on a dry weight basis. Flies in bioassay 1 were mixed sex and unstarved and flies in bioassay 2 were females only and starved 4 h before testing began. LC₅₀s were 8.97 and 14.33%, and LT₅₀s were 59.75 and 53.34 h in bioassays 1 and 2, respectively. Baits were tested at …
