Insecticides Susceptible of Aedes aegypti in Area Responsibility of Office of Disease Prevention and Control 6 Khon Kaen, 2009

Abstract

This study was experimental study. The objective was to determine the insecticide susceptibility of Aedes aegypti Linnaeus larvae and adults, the vectors of dengue fever and dengue hemorrhagic fever, were collected from urban and rural of Disease Prevention and Control 6 Khon Kaen, from January to June 2009.
The patterns of insecticide susceptibility to 0.02%, 1% temephos, 0.75% permethrin, 0.05% deltamethrin, 5% malathion and 0.1% propoxur were monitored follow the guideline of World Health Organization standard and were compared to Bora Bora strain. The results showed the susceptibility test of larvae of Ae. aegypti in all areas were resistant on 0.02 % temephos and were found to be susceptible to 1% temephos. Most adults of Ae. aegypti were resistant to 0.75% permethrin mortality rate 38-75%. But they were susceptible to 0.05% deltamethrin and 5% malathion except those from rural Roi Et was resistant both insecticides mortality rate 68 and 72%. Tend to resist 0.1% propoxur. So the susceptibility test were the best for surveillance on resistance vector. The data were base for insecticide management for suffcient control vector in area. However the best control of disease provided several ways was breeding place.
