To control this disease, public <br>health officers focus on regulating the population of Aedes aegypti larvae. The aims of this research were to <br>study the susceptibility of Ae. aegypti to Bacillus thuringiensis israelensis (Bti) and juvenile hormone, in <br>order to end the spread of this disease in three epidemic DHF outbreak sub-districts of Ladyai, Suanluang and <br>Jompuak. The results revealed that Ae. aegypti is susceptible to Bti and juvenile hormone in all areas, with a <br>100% death rate. Exposure to Bti eradicated the larvae in a very short time of less than 18 hours. In addition, <br>juvenile hormone can completely hinder the growth of Ae. aegypti to adult stages. The results demonstrate <br>the effectiveness of these agents for mosquito larvae eradication. Therefore, insecticidal bacterium and <br>juvenile hormone may be an option to reduce the number of DHF patients in Samutsongkhram, Thailand.</p>}, number={40}, journal={GEOMATE Journal}, author={Tanawat Chaiphongpachara and Jirawan kaebkhunthod and Sedthapong Laojun and Chaekki Kunphichayadecha and Wanvisa Saisanan Na Ayudhaya and Wallapa Wassanasompong}, year={2017}, month={Sep.}, pages={107–111} }
