Abstract
Aedes aegypti has been resistant againts Permethrin insecticide, generally the insecticide resistance development caused by internal factor as genetics. This study was designed to elucidate the mode of inheritance of resistance to permethrin in Ae.aegypti. Bioassay test was conducted to six Ae. aegypti field strains (AntG0, SkjtG0, SkpdG0, BtengG0, BbatG0, and RncsG0) to determine the development of resistance to Permethrin. The results showed that in six field strains, the offspring responses to Permethrin were different and reflected their resistance ability. Reciprocal crossing between resistant parental strain (AntG9) with parental susceptible strain (VCRU) resulted in logarithmic concentration vs probit response of their offspring which were similar to those of the susceptible strain, with degree of dominance values (D) -0.2 (when susceptible parent was male in F1) and -0.1 (when resistant parent was female in F1’). The present study suggested that inheritance of Permethrin resistance was incompletely recessive and was autosomal inheritance or has no maternal effect. Permethrin resistance in Ae. aegypti was apparently being controlled by one gene.
