Problems solved by technology

In addition, there are some schemes that mentioned that mixed populations of host plants broad bean and pea aphid, Prunus pea aphid, and bean aphid adults and nymphs can be used to raise aphid-eating gall midges, but this scheme did not calculate the feeding effect of the mixed population, and the broad bean It has the problems of long seedling raising cycle and low planting density, so the overall amount of aphid inoculation and feeding efficiency of aphid gall midges are bound to be limited

Embodiment 1

[0037] This embodiment provides a method for raising aphid-eating gall midges by utilizing a variety of aphid mixed populations on barley, such as figure 1 shown, including the following steps:

[0038] (1) Planting of host plants: Soak Lianpi No. 9 barley seeds in water for 6 hours, fill the seedling pots (50×20×12 cm) with nutrient soil, and spread the soaked barley seeds evenly into the seedling pots, Cover with a thin layer of soil, preferably just covering the barley seeds, and then water evenly with a watering can. The temperature was kept at 25°C, the humidity was 75%, and the light was sufficient.

[0039] (2) Propagation of a single species of aphids: Propagate corn aphids, corn aphids and wheat long tube aphids respectively in different breeding rooms to ensure the purity of the three aphids. adequate;

[0040] During the breeding period of a single species of aphids, it is necessary to replace the seedlings. The method of replacing seedlings is: set up a square (...

Embodiment 2

[0046] This embodiment provides a method for raising aphid-eating gall midges by utilizing a variety of aphid mixed populations on barley, such as figure 1 shown, including the following steps:

[0047] (1) Host plant planting: Soak Lianpi No. 9 barley seeds in water for 8 hours, fill the seedling pots (50×20×12 cm) with nutrient soil, and spread the soaked barley seeds evenly in the seedling pots, Cover with a thin layer of soil, preferably just covering the barley seeds, and then water evenly with a watering can. The temperature was kept at 30°C, the humidity was 85%, and the light was sufficient.

[0048] (2) Propagation of a single species of aphids: Propagate corn aphids, cereal aphids and wheat long tube aphids respectively in different breeding rooms to ensure the purity of the three aphids. adequate;

[0049] During the breeding period of a single species of aphids, it is necessary to replace the seedlings. The method of replacing seedlings is: set up a square (2×2 ...

Abstract

The invention relates to a method for raising aphid-eating gall midges by using a mixed population of various aphids on barley. In the method, barley seedlings are selected as host plants, and three kinds of aphids mixed populations of corn aphid, corn aphid and wheat long tube aphid are used. As an intermediate host, the aphid-loaded wheat seedlings of the three aphid mixed populations were used to breed the aphid gall midge, so as to improve the large-scale reproduction efficiency of the aphid midge. The invention uses barley as a host plant, and has the characteristics of short seedling raising period, high planting density, large aphid loading capacity and the like. Simultaneously, the present invention also adopts the method of raising aphid-eating gall midges in mixed populations of three different aphids (maize aphid, cereal aphid and wheat long tube aphid), which further improves the large-scale reproduction efficiency. In the case that the prey aphid load on the host plant has an upper limit, increasing the number of eggs laid by aphid gall midges by increasing the species of aphids has opened up a new way to improve the efficiency of large-scale reproduction.

Description

technical field [0001] The invention belongs to the technical field of biological control of agricultural pests, in particular to a method for artificial batch breeding of aphid gall midges. Background technique [0002] Aphidoletes aphidimyza belongs to the family Cecidomyiidae of Diptera and is an important predatory natural enemy of aphids. Each aphid-eating gall midge can prey on dozens of aphids in its lifetime, and it has achieved good control effects on crops such as orchard apple aphids, vegetable cabbage aphids, and greenhouse peach aphids. Using aphid-eating gall midges instead of pesticides to control aphids is of great significance in avoiding insecticide resistance, improving product safety, and protecting the environment. The aphid gall midge has the advantages of strong reproductive ability, suitable for mass reproduction, and convenient storage and transportation, and has now achieved commercial production and application. [0003] The current breeding tech...
