Aqueous extract obtained from deoiled neem and karanja seed kernels (ADNSD and ADKSK) were assessed for their toxic and growth regulating activities against Cx quinquefaciatus treated as first instar larvae. ADNSK at various concentrations was effective on the growth regulating mechanism, inducing prolonged larval stages. However, 100% larval mortality was observed, especially during the first and the second instars at all the tested concentrations. ADKSK caused 100% mortality in the fourth instar larvae and prepupae at the concentration of 100 ppm with no significant effect on the developmental period. The adults emerging from treated (50 ppm) larvae were smaller in size and malformed. We found ADNSK to be more effective than ADKSK.
对从去油印楝和刺桐种子仁中获得的水提取物（ADNSD和ADKSK）进行了评估，以研究其对按一龄幼虫处理的致倦库蚊的毒性和生长调节活性。不同浓度的ADNSK对生长调节机制有效，可诱导幼虫期延长。然而，在所有测试浓度下均观察到100%的幼虫死亡率，尤其是在一龄和二龄幼虫期。ADKSK在浓度为100 ppm时导致四龄幼虫和蛹前期100%死亡，对发育期无显著影响。从经处理（50 ppm）的幼虫羽化出的成虫体型较小且畸形。我们发现ADNSK比ADKSK更有效。
