Objective: To study the anti-feeding effect of total ginsenoside of ginseng stems and leaves on Heliothis dipsacea larvae.
Method: The natural growing condition for lavae was simulated indoors. The anti-feeding effect of total ginsenoside on Heliothis dipsacea larvae was studied by leaf disc test.
Result: The total ginsenoside appeared showed a significant antifeeding effect. The Heliothis dipsacea larvae fed with the leaves of soybean treated with 2.0%, 1.0% and 0.5% total ginsenoside, respectively. At 8 h, non-selective anti-feeding rate were 93.40%, 83.42% and 75.19%, and selective anti-feeding rate were 77.53% , 73.58% and 58.86%.
Conclusion: The toatal ginsenoside had significant inhibition effect on Heliothis dipsacea larvae, and inhibition effect increases as the increase of concentration ginsenoside.
