Problems solved by technology

However, there are three obstacles in the process of releasing parasitoid bees in the field to prevent and control Bemisia tabaci: 1. Lack of host plants suitable for local planting and large-scale reproduction of Bemisia tabaci; ; 3. Lack of a simple and operable process for the low-cost release of Bemisia tabaci in the artificial field and can receive better control effects

Embodiment Construction

[0032] A method for improving the parasitic rate of parasitic wasps to whitefly MED cryptic species, the method of the present invention comprises the following steps: (1) cultivation of host plants; (2) breeding of host whitefly nymphs; (3) breeding of parasitic wasps Breeding; (4) Cultivation of bank plants; bank plants refer to plants, food substitutes or beneficial organisms involved in the entire pest management system including bank plants, which are purposefully added or established in pest control The system of raising and releasing bank plants in greenhouse or open field pest control; the plants that release beneficial organisms (such as parasitoid) vectors involved in the present invention are called bank plants; (5) field release of bank plants.

[0033] Further, the cultivation of the host plant of the present invention comprises the following steps:

[0034] (1) Select mint as the host plant of whitefly. Mint is a common and suitable vegetable plant in Yunnan area...

Abstract

The invention relates to a method for increasing the parasitism rate of parasitic wasps in cryptic species of bemisia tabaci gennadius MED. The method includes the following steps of (1) cultivation of host plants; (2) breeding of numphs of bemisia tabaci gennadius; (3) raising of parasitic wasps; (4) cultivation of parasitic plants, storage of parasitic plants and domestication of parasitic plants before releasing; (5) field release of the parasitic plants. The invention provides a method for increasing the parasitism rate of bemisia tabaci gennadius before the parasitic plants are released outside parasitic hives. Stable field population is created, and the demands of field crops for bemisia tabaci gennadius are efficiently controlled.

Description

technical field [0001] The invention belongs to the technical field of a method for increasing the parasitism rate of parasitic wasps to Bemisia tabaci MED cryptic species. Background technique [0002] At present, Bemisia tabaci has become an important pest on tomatoes and other vegetables in the vegetable growing areas of our country. Under natural conditions, Bemisia tabaci is the only carrier of tomato yellow leaf curl virus, which is an important pest in the tomato planting industry. One of the most important viruses, the quality of tomato is seriously affected after the onset, and the yield is reduced, and it can have a devastating impact on tomato production in severe cases. Bemisiatabaci (Gennadius) is a worldwide pest and one of the most invasive species of Bemisia tabaci. It has spread rapidly since it invaded my country in the mid-1990s and is now in Distributed in most parts of my country, and caused serious ecological and economic losses. In recent years, MED c...
