Tea lesser leafhopper preventing and control method

Abstract

The invention relates to the technical field of tea leaf pest prevention and control and aims at providing a tea lesser leafhopper preventing and control method. The tea lesser leafhopper preventing and control method comprises the steps that 1, tea trees are pruned, two branches are reserved on two side of each tea bush to serve as flag branches during tea tree pruning, one bud and three leaves on each flag branch are reserved, and other leaves and side branches on each flag branch except one bud and three leaves are removed; 2, the flag branches processed in the step 1 are utilized to trap and kill tea lesser leafhoppers. The tea lesser leafhopper preventing and control method utilizes tender tips of the flag branches to trap and kill tea lesser leafhopper adults and larvae existing in tea gardens in the time period from pruning to next turn of tea season new shoot germination, pest harm caused by tea lesser leafhopper breeding is avoided, and the method is simple in operation, efficient and harmless.

Description

technical field [0001] The invention relates to tea insect pest control technology, in particular to a method for preventing and controlling tea leafhoppers. Background technique [0002] Tea small green leafhopper, also known as commonly known as leaf springer, floating dust, ring insect, etc., belongs to the family Leafhopper of the order Homoptera. The tea green leafhopper overwinters as adults on the old leaves in the lower part of the tea bushes or on the weeds in the tea garden, and the adults start to feed in the early spring of the next year. After the tea leaves germinate, they lay eggs in the epidermis of the young shoots, resulting in damage to the tea transport tissue and insufficient nutrient supply , is a common pest in tea producing areas. [0003] Based on the needs of food safety and protection of the ecological environment, the existing methods of prevention and control of tea leafhoppers often use external attractants to trap and kill them. However, this ...

Problems solved by technology

However, the practice of tea tree pruning is to cut off all the branches and leaves on the picking surface of the crown. Although it can effectively control the tea green leafhopper, some insect populations barely rely on feeding on the leaves to survive and become latent, and become the source of pests that will cause outbreaks in the next tea season.
