Abstract: AIM:To study the mechanism of the cidal effect of alphamethrin (fendona) against mosquitoes.METHODS:The third instar larvae of Anopheles anthropophagus and Anopheles stephensi were treated with0 .6 97nmol/L and1 .393nmol/L of fendona,respectively.The fourth instar larvae were collected.The protein content,proteinase and carboxylesterase ac- tivities in the fourth instar larvae were determined by spectrophotometric methods.RESULTS:When compared with the control groups,the protein content was increased and the specific activities of proteinase and carboxylesterase were reduced in the treatcd groups, the difference being markedly significant (P < 0. 01). CONCLUSION: The result showed that fendona remarkably influenced the protein content and activities of proteinase and carboxylesterase in the larvae of An. anthropophagus and An. stephensi.
