Chestnut is one of the main pests of chestnut. Larval larvae live in chestnut buds and begin to sprout when chestnut sprouts the following year. The adult larvae sloughed in the infestation and began to emerge in early June. The bees were then removed and stopped in early August. Adults can live 60-72 hours after dislocation and have strong phototaxis.
First, the harm symptoms Symptoms of the chestnut buds were tumor-like, the formation of a hard infestation, so that the chestnut can not be a new branch, severely damaged branches dead, resulting in reduced or no harvest chestnut.
Second, prevention and control methods (a) biological control. Protecting natural enemies of chestnut bee can effectively control the damage of chestnut bee. The main natural enemies of Chlamys farreri are the Chinese green long-tailed wasps, which have a high parasitic rate on the larvae of Chrysopalyma. In the chestnut garden with less medication, the Chinese green long-tailed wasp had a significant inhibitory effect on the chestnut beet. (b) Blacklight trapping of adult worms. From April 20 to the beginning of September, a black light lamp is used to trap adult insects in the chestnut garden. A black light is set for every 10 mu chestnut garden, which can effectively control the damage of the chestnut bee. (c) manual control. Before the end of May, the new insects were completely removed and the overwintering larvae were eliminated. (d) Chemical control. According to the conditions of natural enemies in the chestnut garden, the natural chestnut garden with few natural enemies will be sprayed with fenvalerate emulsion 1500 times at the peak of the adult's dislocation, or the high-effective cypermethrin may be added with imidacloprid 1000-1500 times. The control effect is better.

Beeswax is obtained from the honeycombs of bees after the Honey has been removed by draining or centrifuging. The combs are melted with hot water, steam or solar heat; the melted product is filtered and cast into cakes of yellow beeswax. With detoxification, wound healing, tissue regeneration, pain relieving effect. Commonly used in the ulcer not healing, ecthyma erosion, ulceration of trauma, burn and scald.
