Abstract
Differences in the phosphatase activity of susceptible and DDT-resistant house flies (Musca domestica L.) and susceptible and chlordane-resistant cockroaches (Blattella germanica (L.) and Periplaneta americana (L.)) have been measured. The phosphatase analysis was based upon the colorimetric determination of beta-naphthol liberated from sodium beta-naphtholphosphate. Although significant differences were found in the acid and alkaline phosphatase activity between the sexes of both resistant and susceptible insects and also differences in the acid phosphatase activity between females of one DDT-resistant and one susceptible strain or insects, it was concluded that these differences were due to strain variations rather than to resistance.
