Abstract

Adult bedbugs, Cimex lectularius and C. hemipterus, were killed when allowed to feed on rabbits previously given oral dosages of 228-537 mg. of DDT and 250-400 mg. of pyrethrins per kg. of body wt. In some instances 100% mortality occurred. Stableflies which fed on a few of the rabbits showed typical pyrethrum paralysis in < 1 min. Some DDT dosages showed toxic effect on the rabbit but pyrethrum dosages did not.
