To evaluate the antifeedant, insecticidal and growth inhibition activities of Solanum pseudocapsicum (S. pseudocapsicum) seed extracts against Spodoptera litura (S. litura) and Helicoverpa armigera (H. armigera).
Hexane, diethyl ether, dichloromethane and ethyl acetate seed extracts were prepared and tested for antifeedant, insecticidal and growth inhibitory activities against fourth instar larvae of S. litura and H. armigera.
Ethyl acetate extract showed promising antifeedant and insecticidal activities against S. litura and H. armigera. Percentage of deformed larvae, pupae and adults were maximum in treatment of ethyl acetate extract. Percentage of successful adult emergence was deteriorated by seeds on extract treated larvae.
Ethyl acetate extracts of S. pseudocapsicum, showed higher efficiency of antifeedant, insecticidal and growth inhibition activities. Hence, it can be used to controll agricultural insect pests, S. litura and H. armigera.
评估假辣椒(Solanum pseudocapsicum)种子提取物对斜纹夜蛾(Spodoptera litura)和棉铃虫(Helicoverpa armigera)的拒食、杀虫和生长抑制活性。
制备己烷、乙醚、二氯甲烷和乙酸乙酯种子提取物,并对斜纹夜蛾和棉铃虫四龄幼虫的拒食、杀虫和生长抑制活性进行测试。
乙酸乙酯提取物对斜纹夜蛾和棉铃虫显示出有前景的拒食和杀虫活性。在乙酸乙酯提取物处理组中,畸形幼虫、蛹和成虫的比例最高。提取物处理过的幼虫所对应的种子使成虫成功羽化的比例降低。
假辣椒的乙酸乙酯提取物显示出较高的拒食、杀虫和生长抑制活性效率。因此,它可用于防治农业害虫斜纹夜蛾和棉铃虫。
