Abstract:

To determine the control effect of cyromazine, chlorantraniliprole and spinetoram on Drosophila suzukii larvae, the fruit damaged by D. suzukii was collected and the experiment was carried out by means of insecticide spray. The mortality rate of D. suzukii larvae was calculated on day 1, 2, 3, 4 and 5 after medication. The mortality rates of D. suzukii larvae after 5 days of treatment with 3000, 2500 and 2000 times cyromazine spray were 53.72%, 56.47% and 58.48%, respectively. After 5 days of treatment with 5000, 4500 and 4000 chlorantraniliprole spray, the mortality rates of D. suzukii larvae were 51.49%, 54.85% and 58.42%, respectively. After 5 days of treatment with 2500, 2000 and 1500 times spinetoram spray, the mortality rates of D. suzukii larvae were 41.38%, 43.30% and 49.74%, respectively. Cyromazine and chlorantraniliprole have certain control effect on D. suzukii larvae.
