Abstract:
In order to make clear the overwintering generation and the overwintering place of Rhbdophaga SP, master its biological characteristics and provide the scientific basis to control this insect, the author picked and peeled the galls in the infested wickers, then put the larva and pupa into different environmental conditions to research the characteristic of overwintering and find the overwintering place. The results showed that: the larva and pupa overwintered in the galls of damaged wickers in the current year. The overwintering place of this pest was out of soil. The overwintering generation of the pest was mainly in the galls which were in the scrap after processing and in the outside branches before processing. The galls falling in the field in harvest was the other source. In the practical application, galls must be removed and destroyed centrally after wickers harvest. And the galls falling in the field must be eliminated simultaneously. It could largely reduce the number of overwintering generation after taking such measure. And the perniciousness of Rhbdophaga SP would be remitted the next year.
