Abstract
IT has been found that, in the laboratory, old female Glossina morsitans Westw. show a considerably greater tolerance to some chlorinated hydrocarbon insecticides than do the young flies of both sexes, and in particular that pregnant flies show an exceptional degree of tolerance. Complete log-dosage/probit-mortality regression lines have been determined for dieldrin (Table 1).
