Problems solved by technology

However, under natural conditions, due to the large space and the relatively scattered distribution of host resources, the probability of A. japonica using the female larvae of the same parasitoid to produce male peaks is reduced. Therefore, the number of drones of A. japonica is scarce and it is difficult to reproduce artificially. , their ability to control bemisia tabaci is greatly limited

Embodiment 1

[0021] Example 1 Mass propagation of the Aphidia japonica drone as the secondary host insect

[0022] The specific operation of applying this invention to produce 10000 drones is as follows:

[0023] (1) Cultivation of host plant melon

[0024] Melon seeds are sown in the seedling trays with nutrient matrix and cultivated, 1 seed / hole, and the nutrient matrix is ​​composed of vermiculite: flower nutrient soil and soil; vermiculite: flower nutrient soil: the volume ratio of soil is 1 -1.5:2-4:3-5; Regularly check the germination of melon seeds and the growth of seedlings, and maintain the humidity of the nutrient matrix in the seedling tray. When the melon seedlings grow to 1-2 true leaves, they are transplanted into a nutrient cup with a nutrient substrate for cultivation, 1 plant / cup, and when the melon seedlings grow to 6-8 true leaves, remove the top for later use;

[0025] The cultivation of the host plant melon is carried out in a greenhouse with sufficient light and co...

Embodiment 2

[0035] Example 2 The selection of different secondary hosts by A.

[0036] 1 Materials and methods

[0037] 1.1 Insects to be tested

[0038] Host insect: Bemisiatabaci (Gennadius) type B

[0039] Parasitic wasps: Encarsiasophia (Girault&Dodd) and Eretmocerushayati (ZolnerowichandRose).

[0040] 1.2 Tested host plants

[0041] Melon CucumismeloLinn (Langfang Kelong Seed Co., Ltd., Hebei Province). When the potted melon grows to 6 true leaves, it will be used for later use.

Abstract

The invention relates to the technical field of agricultural pest biological control, in particular to a method for breeding encarsia sophia drones by means of eretmocerus hayati. The method comprises the steps of (1) breeding host plant muskmelon, (2) breeding primary host bemisia tabaci, (3) breeding a secondary host, (4) preparing female parent encarsia sophia, and (5) breeding the encarsia sophia drones. According to the method, the aim of breeding the encarsia sophia drones is achieved, large-scale breeding of the population of the encarsia sophia drones is achieved, insect sources are provided for a province and a region where the bemisia tabaci need to be controlled through the encarsia sophia drones, and the method is an effective and key way for continuously controlling the bemisia tabaci.

Description

technical field [0001] The present application relates to the technical field of biological control of agricultural pests, and in particular to a method for breeding the male peak of Aphids aphids by using Aphidia haidenii. Background technique [0002] Bemisiatabaci (Gennadius), also known as sweet potato whitefly or whitefly, belongs to Hemiptera, Whiteflyaceae, Bemisia genus, and is one of the main pests of more than 600 kinds of plants such as cotton, vegetables and garden flowers. [0003] At present, chemical control is still one of the main control measures of B. tabaci, but the large-scale and continuous use of chemical pesticides has led to the increase of B. tabaci resistance and pollution of the ecological environment. Therefore, all countries in the world have emphasized the comprehensive management policy to Bemisia tabaci, among which biological control is a very important control measure. [0004] Eretmocerushayati (ZolnerowicandRose) belongs to Hymenoptera, ...
