Method for breeding aphids and aphidoletes aphidimyza by means of soilless cultivation of plant

Abstract

The invention relates to a method for breeding aphids and aphidoletes aphidimyza by means of soilless cultivation of a plant. The method comprises the following steps: (1) spreading barley seeds evenly into a specification plate of a seedling breeding tray, and adding water into a water pond; (2) flatly spreading the barley seedlings, fully covered with corn leaf aphids, onto an iron wire mesh; (3) breeding the aphids, adding water into the water pond every day; (4) moving the seedling breeding tray into an aphidoletes aphidimyza inoculation workshop, inoculating by adopting a cover cage way,and liberating on the day of eclosion; (5) moving the seedling breeding tray on which eggs are laid into a development workshop for developing; (6) putting collected larvae into a beaker, washing thelarvae with water absorbed by a suction pipe, and absorbing impurities; (7) putting the collected mature larvae into a box with vermiculite, and storing in an incubator at 10 DEG C. According to the method, the host plant is planted by using a hydroponic culture method for breeding the aphids and the aphidoletes aphidimyza, thus overcoming the defects of using matrix soil to plant the host plant for propagation, and improving the propagation effect and quality of the aphidoletes aphidimyza.

Description

technical field [0001] The invention belongs to the technical field of biological control of agricultural diseases and pests, and relates to a method for propagating aphids and aphid-eating gall midges by planting plants without soil. Background technique [0002] Aphid gall midge is the dominant predatory natural enemy of greenhouse aphids and can be used to control various aphids in greenhouses. The use of aphid-eating gall midges instead of pesticides to control aphids has the advantages of non-toxicity, pollution-free and ecological safety. To realize the field application of aphid-eating gall midges, the large-scale reproduction of aphid-eating gall midges and aphid-eating gall midges must first be realized. The current method of breeding aphid-eating gall midges generally adopts substrate soil to plant host plants, breeds aphids with host plants, and then uses aphids to breed aphid-eating gall midges. There are many problems in the breeding process. First of all, the...

AI Technical Summary

Problems solved by technology

The first is the problem of heavy work and excessive workload. This method needs to prepare matrix soil, fill planting containers, carry planting containers, etc.

Next is the difficult problem of water and fertilizer management. This method needs to pour fertilizer water into the matrix soil, which is very prone to excessive humidity and airtightness of the matrix soil in rainy days for a long time, and the host plants cannot bear it and the roots rot

The third is the problem of substrate soil when collecting mature larvae of aphid gall midges in the later stage. It is necessary to remove impurities many times, otherwise the accuracy of measurement will be affected.
