Problems solved by technology

When the insect population density is high, the leaves appear black, which seriously affects photosynthesis. After bemisia tabaci damages tobacco, it causes leaf yellowing and white veins to reduce photosynthesis, which in turn affects the quality of tobacco leaves.

Abstract

The present invention provides a method for group breeding encarsia formosa in-door. The method comprises the following steps: (1) breeding method for whitefly, the method comprises that: daily transferring whitefly on fresh common bean seedlings with four leaves in first climate chamber for inoculation, wherein each cage is planted with four seedlings, each seedling is inoculated with 50 whitefly adults in the cages, and the conditions in the climate chamber is: L: D / / 14: 10, T / / 26-28 DEG C, TH / / 50-60%; after 24 hours, expelling the whitefly adults which have oviposited with a hair blower; transplanting the common bean seedlings with eggs to another climate chamber to feed for 10 days, when nymphs develop to 2-3 instars, one part of the plants are used to inoculate breeding encarsia formosa, and the other part of the plants are used to breeding whitefly; wherein conditions of the second climate chamber is: L: D / / 14: 10, T / / 25-27 DEG C, TH / / 50-60%. According to the method, encarsia formosa can be continuously and rapidly bred in high yield, so that damage caused by whitefly can be effectively controlled.

Description

technical field [0001] The invention belongs to the field of pest control, in particular to the field of pest biological control, and belongs to a method for controlling tobacco bemisia tabaci by utilizing the lily aphid wasp. Background technique [0002] Bemisia tabaci: The scientific name Bemisia tabaci (Gennadius) belongs to the Homoptera whitefly family, commonly known as the small white moth, the main damage crops: tobacco, tomato, sweet potato, cassava, cotton, cruciferous, cucurbitaceae, legumes, solanaceae, Malvaceae, etc. Adults and nymphs of Bemisia tabaci directly suck plant sap, causing plant weakness, and nymphs and adults can also secrete honeydew, which induces the generation of soot. When the insect population density is high, the leaves appear black, which seriously affects photosynthesis. After bemisia tabaci damages tobacco, it causes leaf yellowing and white vein reaction to reduce photosynthesis, which in turn affects the quality of tobacco leaves. Be...
