Da. Ostlind et al., A novel Cimex lectularius (Hemiptera; Cimicidae) - Rodent assay for the detection of systemic ectoparasiticide activity, SW ENTOMOL, 26(3), 2001, pp. 181-186
The systemic anti-ectoparasitic activity of ivermectin, cythioate and closa
ntel was detected by a novel assay using fourth instar Cimex lectularius L.
fed on orally-treated mice (medicated diets). The criteria for activity ag
ainst the insect were death, paralysis and molt delay. The minimum effectiv
e dietary levels of drug when fed for five days were 0.093 (molt delay), 0.
312 (paralysis) and 15.6 (molt delays ppm. for ivermectin, cythioate and cl
osantel, respectively.
