A method for preventing and controlling Bemisia tabaci in facility vegetables

Abstract

The invention discloses a method for preventing and treating facility vegetable bemisia tabaci through eretmocerus sp. A plastic flower pot, culturing substrates, tobacco seedlings and a fly net are selected to form an integrated device, and the purposes of expanding the propagation of the eretmocerus sp and preventing and treating the facility vegetable bemisia tabaci are realized. The method disclosed by the invention is favorable for establishing eretmocerus sp population which is suitable for production and of which the population quantity is large enough through expanding propagation of the small-group eretmocerus sp, after the release of the eretmocerus sp population, the adaptation capacity of the eretmocerus sp to field environment is high, the parasitic rate of the eretmocerus sp to the bemisia tabaci is high, the insect population density of the bemisia tabaci can be effectively reduced, and the preventing effect can reach more than 80%.

Description

technical field [0001] The invention relates to a method for preventing and controlling Bemisia tabaci in facility vegetables by Aphidia radiata, in particular to a method for multiplying and controlling Bemisia tabaci in vegetables, and belongs to the technical field of vegetable biological control. Background technique [0002] Aphid aphidus is an important natural enemy of whitefly, whitefly and other pests. It has biological characteristics such as wide distribution, large amount of feeding or parasitism, and strong fecundity. It is a natural enemy insect with broad development and utilization prospects. [0003] At present, the biocontrol technology using natural enemy insects to control pests has become a powerful measure to ensure the development of green agriculture in my country. The commercialized products of Aphidus aphidatus use pupae as the applied insect state, and the pupae of Aphididae is made into bee cards, which have been successfully applied to the contro...

AI Technical Summary

Problems solved by technology

[0004] At present, there are still many deficiencies and defects in the application of the commercialized Aphididae wasp in the cultivation of vegetables in solar greenhouses.

The humidity in the solar greenhouse is high, so it is difficult to ensure that all the released bee pupae can effectively emerge and survive. After the release of the product of the commercial bee, it is difficult to establish a population with a large enough population in the solar greenhouse, which affects the control effect on Bemisia tabaci; (2) Large dosage and high cost

In order to achieve the ideal control effect, it is necessary to release a large group of commercialized bee products of Aphidus oculus, resulting in high cost of control, vegetable farmers are unwilling to accept it, and it is difficult to promote in production
