Lycium barbarum gall mite and its control

Published: 2024-11-05 Author: mysheen
Last Updated: 2024/11/05, Lycium barbarum gall mite belongs to the family gall mites. In order to damage leaves, tender shoots, petals, buds and young fruits of Lycium barbarum, purple or yellow diseased galls were formed in the affected parts. Lycium barbarum gall mites overwintered as mature adult mites in the scales of winter buds or in the cortical cracks of branches. In April of the following year, adult mites moved to the new leaves of old branches to lay eggs, and after hatching, nymphs invaded plant tissues to cause galls. Gall mites climbed from galls to new shoots in mid-late May, and the first peak period of reproduction was formed in late June. By the middle of August, when the autumn shoots grow, the gall mites turn to the new shoots.

Gall mites climbed from galls to new shoots in mid-late May, and the first peak period of reproduction was formed in late June. In the middle of August, when the autumn shoots grow, the gall mites turn to the new shoots again. September is the second peak period of reproduction, and lll months enter dormancy, and many generations occur in a year.

Before the winter bud germination is the appropriate period for control, it can be sprayed with 45% Mel 50% sulfur gel suspension 300x solution, which can also control mites, or with 40% omethoate 1000 times diluent spray.
