摘要: Citrus aurantium (L.) peel extracts in petroleum ether were evaluated for toxicity against olive fruit fly, Bactrocera oleae (Gmelin) and medfly, Ceratitis capitata (Wiedemann) adults. flies more susceptible to the extract than C. contact residual bioassays. Fumigation bioassay had no effect. Both sexes of B. equally both types However, males conspecific females. LD 50 values (concentration causing 50% mortality) after 96 h females 44.8 40.1 μg/insect through topical application. Whereas, 38.8 67.8 respectively. LC 18.8 17.8 μg/cm 2 Petri dish bioassay. 70.6 147.1 Fractionation on a silica gel column with three different polarity solvents resulted fractions only intermediate solvent fraction having substantial insecticidal activity. Toxicity mixtures active inactive was equal original extract. Our results indicate that has potential controlling insect pests.
