Effects of benzylphenol and benzyl-1,3-benzodioxole derivatives on fertility and longevity of the yellow fever mosquito (Diptera:Culicidae).

Abstract

Neither chemosterilants J2644 (2,4-bis(1,-1-dimethylethyl)-6-(4-methoxyphenylmethyl)phenol) nor J2581 (5-ethoxy-6-(4-methoxyphenylmethyl)-1,3-benzodioxole) affected fertility of male and female Aedes aegypti (L.), significantly when pupae were treated at 1 to 5,000 ppm concentrations. The observed reduction in hatchability of eggs from normal females mated with treated males did not exceed 32%. The reduction in hatchability of eggs from treated females mated with normal males was ca. 28%. Longevity of males (5,000 ppm) was not affected by either sterilant at indicated doses.
