| Abstract: | Objective] The aim was to study on antifeedant activity of purslane petroleum ether extract on corn leaf aphid under different condi-tions.Method] Using single factor and orthogonal test, the antifeedant activity of purslane petroleum ether extract on corn leaf aphid under dif-ferent concentration, temperature and time was studied . Result ] The results showed that under concentration of 100 mg/mL, temperature 25 ℃, time 48 h, the antifeedant activity of purslane petroleum ether extract was the highest .Extract concentration was the key factor influencing the antifeedant activity, followed by time factor.Conclusion] The study provides theoretical basis for development of vegetable insecticide with purslane as raw material. |
