The main reason lies in the defects of biopesticide itself: entomopathogenic nematodes are affected by soil properties, climate temperature, etc., and their colonization activity is high, so it is difficult to popularize; botanical pesticides such as matrine are easy to decompose and have a short duration; Some biological agents such as Beauveria bassiana and Bacillus thuringiensis have unstable control effects due to the influence of temperature, soil properties, ultraviolet rays, etc., and are limited to a few large-scale planting bases.

Abstract
The invention relates to the technical field of biological pesticides, and concretely relates to a technology for preparing a Bradysia odoriphaga harm control preparation from composite biological fungi. The technology comprises the following steps: preparing the composite biological fungi through mixing Beauveria bassiana, Bacillus thuringiensis and Empedobacter brevis, and mixing and fermenting the composite biological fungi, assistants and auxiliary materials to obtain a biological pesticide for controlling Bradysia odoriphaga. The biological pesticide has the advantages of substantial Bradysia odoriphaga control effect, stable performances, wide range of applicable areas, environmental protection, and safety to the health of human bodies.
Description
technical field [0001] The invention relates to the technical field of biopesticides, in particular to the technical field of using compound biological bacteria to prepare preparations for preventing and controlling leek maggot hazards. Background technique [0002] Although leek is a traditional vegetable in our country, leek is delicious, but leek maggots are difficult to prevent. Chive maggots belong to the order Diptera and belong to the family Oculomidae. It mainly harms lily vegetables such as leeks, green onions, shallots, and garlic, as well as lettuce, green vegetables, and celery. It can harm more than 30 kinds of vegetables in 7 families including Liliaceae, Compositae, Chenopodiaceae, Cruciferae, Cucurbitaceae, Umbelliferae, etc., distributed in Beijing, Tianjin, Shandong, Shanxi, Liaoning, Jiangxi, Ningxia, Inner Mongolia, Zhejiang, Sichuan It is a destructive pest in the production of leeks in China, Hubei, Taiwan and other places. It mainly harms the bulbs a...
