What are the control methods for the wolfberry gall mite?

Medicinal Herb Cultivation 0 views
The wolfberry gall mite belongs to the family Eriophyidae. It damages wolfberry leaves, tender shoots, petals, flower buds and young fruit, and the damaged parts form purple or yellow diseased galls. The wolfberry gall mite overwinters as mature adult mites inside the scales of wolfberry winter buds or in cracks in the bark of branches. When leaves unfold in April of the following year, the adult mites migrate to the new leaves on old branches to lay eggs; after hatching, the nymphs invade the plant tissues and cause galls. In mid-to-late May, the gall mites crawl from the galls onto new shoots to cause damage, continuing until late June, forming the first peak period of reproduction. By mid-August, when the autumn shoots grow, the gall mites move again to the new shoots to cause damage

By mid-August, when the autumn shoots grow, the gall mites move again to the new shoots to cause damage; September is the second peak period of reproduction, and in November they enter dormancy, producing multiple generations a year.

Before the winter buds sprout is the suitable time for control. A 300-fold diluted spray of 45%-50% sulfur suspension concentrate can be used, which also controls rust mites; or a 1000-fold diluted spray of 40% omethoate can be used.
