Field evaluation of the combination of larvicide and rice stem immersion to improve lethal ovitrap effectiveness in dengue vector control

Abstract The combination of temephos and attractants from O.sativa was effective for lethal ovitrap in laboratory testing. However, the effectiveness field application needs further investigation. study’s objective to determine influence installation sites, season variation, attractant on efficacy. study used a quasi-experimental design. Lethal ovitraps were installed indoors outdoors 102 houses observed 14 weeks. Statistical analysis conducted with univariate analysis, independent t-test, Mann-Whitney Test. statistical results showed no significant difference positive between LOA LONA indoor outdoor applications. number trapped eggs not affected by applied LO during observations. can be as vector control instrument without addition attractants. is more dry when mosquito population lower than rainy
