The anthelmintics Vermox (mebendazole) and Povan (pyrvinium pamoate) were tested for their effectiveness against thelastomatid nematode, Leidynema portentosae and Hammerschtnidtiella diesingi, infections in the cockroach, Gromphadorhina portentosa. Vermox was tested in doses ranging from 0.2 mg to 5 nig and Povan was tested in doses ranging from 0.1 mg to 12.5 mg. Vermox was found much more effective in curing the thelastomatid infection of cockroaches than Povan. Although Povan was able to reduce markedly the infection rate of the adult nematodes, it was significantly less effective on the thelastomatid juveniles and on the adult H. diesingi. Host sex had no noticeable impact on the sensitivity of either nematode to either anthelmintic at all dose levels tested. The results obtained with the G. portentosa system were in agreement with studies in other host-parasite systems.
