Embodiment 1

[0030] A method for artificially cultivating tea net stinkbugs, characterized in that, the following steps are carried out:

[0031] (1) Feeding the first generation of adults

[0032] Collect tea tree branches with nymphs of the tea net bug, raise the nymphs on the branches to adults, select robust, equal amount of female and male adults of the tea net bug within one day of eclosion, place them in a petri dish, and raise the adults to the early stage of oviposition, Moist filter paper is covered in the petri dish, and tea branches containing leaves are placed to provide growth nutrients;

[0033] (2) Tea seedlings inoculated with worms and laid eggs

[0034] Get the adult of the early stage of laying eggs that step (1) raises and inoculate to the adult leaf of the bud of the 3-5 leaf under the bud of the branch of the living tea tree seedling planted by the root control device more than 3 years, 8 female adults on each leaf, 2 male adults, then cover the adult leaves with g...

Abstract

A method for artificially breeding Stephanitis chinensis Drake comprises the following steps: collecting Stephanitis chinensis Drake nymphs, feeding the Stephanitis chinensis Drake nymphs to the egg laying early stage of adults, inoculating living tea tree seedling leaves planted by a root controller with adults which begin to lay eggs to for egg laying, removing the adults after egg laying, putting the tea tree seedlings loaded with Stephanitis chinensis Drake eggs into an incubator for incubation, and after the Stephanitis chinensis Drake eggs are incubated into nymphs, putting the nymphs into a constant-temperature culture dish to be fed into adults. According to the method, the egg period time of the Stephanitis chinensis Drake is effectively shortened, the average egg period is 43-46 days, the egg period is increased to 5 generations per year from 2-3 generations per year in the nature, the incubation rate of the bred Stephanitis chinensis Drake eggs reaches up to 89.77%, the survival rate of nymphs reaches 69.1% in the process that the nymphs are bred into adults, the average egg laying amount of the adults reaches 43.64 eggs per female insect, the nymphs and the adults are robust, the biological consistency is high, and as an experimental population, a research basis is provided for the exploration of subsequent effective prevention and control measures.

Description

technical field [0001] The invention relates to the technical field of tea tree pest research, in particular to a method for artificially cultivating tea net bugs. Background technique [0002] Tea net stinkbug belongs to the genus Cortex stinkbug of Hemiptera, which is distributed in Hubei, Hunan, Shaanxi, Sichuan, Chongqing and other places, and mainly harms tea trees and camellia oleifera. The adults and nymphs of the tea net bug cluster on the back of the leaves and suck the juice, and their eggs are laid in the mesophyll tissue of the tea tree. Intensive and irreversible white spots appear on the front of the damaged leaves. From a distance, the tea garden is gray and white. On the back of the damaged leaves, there are a large amount of black colloidal excrement, molting and mold growth, which seriously affect the photosynthesis of the tea tree. When the insect is serious, it can cause the leaves to fall off, causing the tree to weaken, and the tea buds to germinate sl...
