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 feeding aphidoletes aphidimyza by utilizing a mixed population of various aphids on barley. According to the method, barley seedlings are selected as host plants,a mixed population of three aphids including corn aphids, rhopalosiphum padi and macrosiphum avenae is taken as an intermediate host, aphid-carrying barley seedlings of the three-aphid mixed population are used for breeding aphidoletes aphidimyza, and the large-scale breeding efficiency of the aphidoletes aphidimyza is improved. Barley is used as a host plant, and the method has the advantages ofbeing short in seedling raising period, high in planting density, large in aphid carrying capacity and the like. Meanwhile, the invention further discloses the method for feeding the aphidoletes aphidimyza by adopting the mixed population of three different aphids (corn aphid, rhopalosiphum padi and macrosiphum avenae), so that the large-scale propagation efficiency is further improved. Under thecondition that the prey aphid bearing capacity on a host plant has an upper limit, the egg laying amount of the aphidoletes aphidimyza is increased by increasing the aphid variety, and a new way forimproving the large-scale propagation efficiency is opened up.

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...
