Method of preventing Basilepta melanopus Lefevre

Abstract

The invention belongs to the technical field of tea tree insect disease prevention and discloses a method of preventing Basilepta melanopus Lefevre. The method comprises steps of plowing the soil and trenching, trimming and backfilling tea trees, additionally applying biological agent fertilizers, covering a mulching film and irrigating. By the use of trimming measurements and the additional application of the biological agent fertilizers, tea output reduction due to trimming, great artificial reproduction release technological difficulty, low insect-virus pesticide efficiency and environmental pollution due to the use of chemical pesticides in the traditional agricultural prevention can be overcome. Damaged plant rate can be reduced to 2% and each branch only has two leaf holes when the method is applied to prevention of the Basilepta melanopus Lefevre, so damaged amount can be obviously reduced. Soil can be improved and insects can be prevented; nutrients required by tea trees can be increased; direct meaning is provided for output and income increase and environment protection; and important reference value is provided for re-use of tobacco stems, tea bran and tea tree trimmed branches and the realization of circular economy of reutilizing wastes.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of tea plant diseases and insect pests, and in particular relates to a method for preventing and controlling the tea horn beetle. Background technique [0002] Tea horn beetle (Baslptiealnp, Lefevre), also known as black foot horn beetle, belongs to Coleoptera (Chrysome Ha ze) and is an important pest of tea trees in the tea region of South my country. Damage characteristics: Adults bite the new shoots and young leaves of tea trees, the leaves are broken and irregular holes, and the growth of new shoots of tea trees is blocked; larvae bite the fibrous roots of tea trees in the soil, and when the damage is serious, the leaves fall early, resulting in a reduction in summer tea production , and weaken the tree vigor, affecting the quality of tea. Life habits of the tea horn beetle: Adults have no phototaxis; eggs are produced in the tea garden topsoil and litter; larvae feed on tea tr...
