At present, it has been widely promoted and used in tobacco planting and production, but it is less used in other crops, because the natural enemy Aphidida has not been found to match the parasitic aphids on different crops.

Embodiment Construction

[0016] Provide specific examples below for further description:

[0017] The domestication and cultivation of Aphids persicae is completed in three steps:

[0018] The first step: planting of media crops, the first domestication of aphids and Aphids aphids

[0019] 1. Breeding shed setup: use steel to build a length×width×height 8×3×1.7m scaffold, and lay 60-mesh insect-proof nets outside to form two breeding sheds, one for aphid breeding and the other for domesticating Aphids persicae;

[0020] 2. Planting of medium crops: plant radish vegetables in two breeding sheds, with a planting density of 2000 plants / mu, to meet the water, fertilizer, light and temperature conditions required for radish growth as much as possible;

[0021] 3. Cultivate early aphids: When the radish vegetables grow to four leaves and one heart, select the rape plants with aphids, namely the original aphids, from the field rapeseed and transplant them to two breeding sheds to be mixed with the radish ve...

Abstract

The invention discloses a method for preventing and controlling rape aphids with tamed tobacco Asaphes vulgaris Walker. aphids are bred by means of host plants; Asaphes vulgaris Walker is inoculated and bred by means of the aphids and the propagated Asaphes vulgaris Walkers are released to the field for controlling aphids. Three times of passage domestication and cultivation are performed on rape aphids through medium crops and host crops planted in an enclosed breeding shed, and tobacco Asaphes vulgaris Walkers are synchronously tamed; According to the method of the invention, radish is used as the medium crops for inoculating rape aphids and three times of passage domestication are performed on Asaphes vulgaris Walkers so that adult wasps which have strong affinity with rape aphids are bred; the propagated Asaphes vulgaris Walkers are released for controlling field rape aphids; the method is practical and economic.

Description

technical field [0001] The invention relates to biological control, in particular to a method for domesticating aphids aphids to control rape aphids. Background technique [0002] Aphid wasps belong to a group of parasites that are natural enemies of aphids that damage a variety of crops. The use of Aphididae to control aphids can greatly reduce the amount of pesticides and improve the safety performance of agricultural products. At present, it has been widely promoted and used in tobacco planting and production, but it is rarely used in other crops, because the natural enemy Aphidida aphids that matches the parasitic aphids on different crops has not been found yet. Whether it is possible to use the Aphididae to control aphids that harm rapeseed is a new topic, because there is a high affinity between the Aphididae and the aphid, and correspondingly, the affinity for the rapeseed is less than 5%. The control effect of Aphididae depends entirely on the affinity between Aph...
