The distribution and inhibition of esterase activity among body of the resistant Crawford and susceptible CSMA strains of male German cockroach, Blattella germanica (L.), were evaluated with α- and β-naphthyl esters using a spectrophotometric assay and native polyacrylamide gel electrophoresis. The esterase activities in the Crawford strain were significantly higher than in the CSMA strain in most tissues except midgut and male genitalia, where the activities were similar. In both strains, isozyme a was dominant in the brain and fat body and isozymes c and d were more abundant in the midgut; but in addition to isozyme a, isozyme …

Virulence of Metarhizium anisopliae (Metschnikoff) Sorokin strain ESC-1 against the German cockroach, Blattella germanica (L.), was determined using 5 concentrations ranging from 83107 to 23109 spores per milliliter. The calculated LD50 value was 4.18 by 108 spores per milliliter (4.18 3 105 spores per cockroach). In vitro study was conducted to determine the compatibility of M. anisopliae strain ESC-1 with chlorpyrifos, propetamphos, and cyfluthrin. Insecticides did not affect conidial germination but did adversely affect the growth and sporulation of M. anisopliae strain ESC-1. The growth of M. anisopliae colonies on media amended only with 50 and 500 ppm of chlorpyrifos …
