      Abstract
      Aedes aegypti and A. albopictus mosquito is increasing problem of public health, being the vector responsible for dengue and chikungunya. Various effort have been done to control the mosquitoes both chemically and naturally. Croton tiglium and Jatropha curcas seed oil were known to posses insecticide activity against larval mosquito species. The study was aimed to examine effectiveness of C. tiglium seed oil and J. curcas seed oil as larvicidal, anti-oviposition, and ovicidal against A. aegypti and A. albopictus, and quantitative analysis of piperine achieved by spectrophotometer. C. tiglium seed oil possessed a significantly higher larvicidal activity against the 3th-4th instar larvae of A. aegypti and A. albopictus than J. curcas seed oil. The larval mortality was observed after 24 h of exposure. The LC50 value of C. tiglium seed oil and J. curcas seed oil were 769.52 ppm and 1366.07 ppm respectively, against A. aegypti and 707.78 ppm and 905.29 ppm respectively, against A. albopictus. There was a decrease in the number of eggs laid by A. aegypti and A. albopictus with C. tiglium and J. curcas oil (≤ 5% eggs) if compared to control (> 50% eggs). C. tiglium and J. curcas seed oil was effective on 0.4%-0.5% concentration so that could prevent the eggs from being hatched (> 90%). Quantitative analysis of C. tiglium and J. curcas by spectrophotometer revealed the presence of piperine were 0.0385% and 0.0054%. The content of C. tiglium was higher compared to J. curcas as proved by the value of LC50. The result of this study suggested that the C. tiglium and J. curcas oil posses insecticide properties that could be developed and used as natural insecticide for larval mosquito control.
