Last Updated: 2024/11/22, Lycium barbarum mite belongs to the family gall mites. Swarms of worms densely cover the leaves to absorb juice, making the leaves ferruginous and early fall. Adult mites overwintered in bark crevices and bud axils. In mid-April of the following year, Chinese wolfberry began to do harm after leaf development, and began to spawn in late April. The peak period of reproduction was from late May to late June. After that, the leaves became ferruginous, the nutritional conditions deteriorated, and the number of mites decreased greatly. New leaves were issued from the end of July to early August, and the second propagation peak appeared. The adult mites transferred to branches after falling leaves in mid-September.

Adult mites overwintered in bark crevices and bud axils, began harmful activities after leaf development of Chinese wolfberry in mid-April of the following year, began to lay eggs in late April, and reached the peak of reproduction from late May to late June. After that, due to the rust color of leaves and deterioration of nutritional conditions, the number of mites decreased greatly, new leaves were issued from the end of July to early August, and the second propagation peak appeared, and reproduction was slow in mid-September. After falling leaves in October, adult mites were transferred to branch cracks to spend the winter.

Spraying the tree crown in the first ten days of May with 300x solution of 50% sulfur gel suspension can control its occurrence if it is controlled in time, and the control effect can be achieved by spraying 1000 times of omethoate.
