摘要

We developed a rapid and economical in vitro procedure with which to evaluate the efficacy of candidate repellents against chiggers. The procedure requires only 5 min and a small number of chiggers to obtain a valid estimate of the median effective dose. We used this procedure to evaluate the repellent activity of 11 compounds against the chigger, Leptotrombidium imphalum Vercammen-Grandjean and Langston. Median effective doses were determined for 10 of the 11 compounds. DM-165-2 (N,N-diethyl-3-flurobenzamide) was the only compound that was significantly more effective than deet.
