Embodiment 1

[0026] In this implementation case, tobacco is used as a control plant to breed Limas aphids. Except for the cultivation of tobacco, other breeding processes are consistent with yacon. The main steps of this implementation case are as follows:

[0027] (1) Cultivation of healthy host plants

[0028] Cultivation of yacon: grow seedlings of yacon balls in a cultivation pot, and after emergence, 4 leaves grow (3~4 leaves with a single leaf area of ​​10~15cm 2 ), transplanted into containers and grown to 8-12 leaves for later use. During the cultivation process, the nutrient solution is poured once every 15-20 days (the composition of the nutrient solution is urea and diammonium phosphate, the ratio of the two fertilizers is 3:1, and the dilution is 25-30 times.) Every 10 days, a batch of seedlings is raised, and every 10 ~15 days to transplant a batch to ensure sufficient supply of plants. The climate conditions in the nursery room are 18-28°C, 40-60% R.H., and the light condit...

Embodiment 2

[0067] This example is the same as Example 1, the only difference being that the time for inoculation of Limephid wasps was changed from 24 h to 48 h.

Embodiment 3

[0069] This example is the same as Example 1, the only difference is that the time for inoculation of Liphid wasps was changed from 24 h to 72 h.

Abstract

The invention discloses a method for a large number of breeding of Lepidos wasps based on yacon as a host plant, and relates to a new method for breeding Lepidos wasps, which uses yacon as an intermediate host plant and whitefly in a greenhouse as a host to carry out Industrial mass breeding of Aphid wasps: (1) Cultivation of healthy yacon plants; (2) Greenhouse whitefly seedling breeding; (3) Greenhouse whitefly host nymphs mass breeding; (4) Greenhouse whitefly seedling production ; (5) Aphid wasps breed in large numbers. The present invention uses yacon as an intermediate host plant to breed a large number of Lepidos wasps, shortens the breeding cycle of greenhouse whitefly and Lepidos wasps, further improves the quality of large-scale breeding of Lepidos wasps, and is suitable for industrial breeding of Lepidos wasps have a positive meaning. The breeding cycle of whitefly and wasps further improves the mass breeding quality of wasps, which is of positive significance to the industrial breeding of wasps.

Description

technical field [0001] The invention discloses a method for multiplying a large amount of aphid wasps based on yacon as a host plant, relates to a new method for breeding aphid wasps, and belongs to the field of biological control of agricultural and forestry pests. Background technique [0002] Whitefly belongs to Hemiptera (Hemiptera), whitefly family (Aleyrodidae), and is one of the important pests in a class of agricultural production. Biological control of whitefly pests is considered to be the safest and most effective means of control. Lithium aphid Encarsia formosa Gahan against whitefly Bemisia tabaci (Gennadius) and the greenhouse whitefly Trialeurodes vaporariorum (Westwood) is considered to be one of the most classic control cases of biological control. Since the introduction of Lepidopteris from the United Kingdom in 1978, my country has done a lot of preliminary research on it and organized relevant units to produce and release it. Compared with chemical ...
