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