Embodiment 1

[0022] The corn aphid feeding method suitable for the breeding of aphid gall midge described in the present embodiment comprises the following steps:

[0023] (1) Planting barley seedlings: plant barley in glass greenhouses according to conventional methods, and inoculate aphid larvae on the barley seedlings after 2 days after the emergence of barley seedlings, for subsequent use;

[0024] (2) Receive aphids: move the barley seedlings inoculated with aphids into the climate chamber, set up a wire mesh, put the barley blades with aphids on the wire mesh, and remove the old blades after one day;

[0025] (3) Control climate indoor temperature 24-26 ℃, relative humidity 60%-70%, photoperiod L13:D11, light intensity 3000lx, carry out the breeding of aphid, inoculate aphid larva again after aphid grows 7-8 days simultaneously, treat aphid When the density reaches 20 heads per leaf, it can be used for inoculation and breeding of aphid gall midges.

Embodiment 2

[0027] The corn aphid feeding method suitable for the breeding of aphid gall midge described in the present embodiment comprises the following steps:

[0028] (1) Planting barley seedlings: plant barley in glass greenhouses according to conventional methods, and inoculate aphid larvae on the barley seedlings after 3 days after the emergence of barley seedlings, for subsequent use;

[0029] (2) Receive aphids: move the barley seedlings inoculated with aphids into the climate chamber, set up a wire mesh, put the barley blades with aphids on the wire mesh, and remove the old blades after one day;

[0030] (3) Control climate indoor temperature 24-26 ℃, relative humidity 60%-70%, photoperiod L14:D10, light intensity 2000lx, carry out the breeding of aphid, inoculate aphid larva again after aphid grows 7-8 days simultaneously, wait for aphid When the density reaches 20 heads per leaf, it can be used for inoculation and breeding of aphid gall midges.

Embodiment 3

[0032] The corn aphid feeding method suitable for the breeding of aphid gall midge described in the present embodiment comprises the following steps:

[0033] (1) Planting barley seedlings: plant barley in glass greenhouses according to conventional methods, and inoculate aphid larvae on the barley seedlings after 3 days after the emergence of barley seedlings, for subsequent use;

[0034] (2) Receive aphids: move the barley seedlings inoculated with aphids into the climate chamber, set up a wire mesh, put the barley blades with aphids on the wire mesh, and remove the old blades after one day;

[0035] (3) Control climate indoor temperature 24-26 ℃, relative humidity 60%-70%, photoperiod L15:D9, light intensity 4000lx, carry out the breeding of aphid, inoculate aphid larva again after aphid grows 7-8 days simultaneously, wait for aphid When the density reaches 20 heads per leaf, it can be used for inoculation and breeding of aphid gall midges.

Abstract

The invention belongs to the technical field of insect artificial propagation, and particularly relates to a corn aphid breeding method suitable for breeding aphid-eating gall midges, and an annual artificial propagation method of aphid-eating gall midges by utilizing the method. According to the corn aphid breeding method suitable for breeding aphid-eating gall midges, provided by the invention,various parameters in an aphid growing process are controlled, the light period is controlled to be L13-16:D8-11 and the light intensity is controlled to be 2000-4000lx, so that the survival rate of bred aphids is high, the life and the reproduction period of adult aphids are long, and the average reproduction capacity is higher.

Description

technical field [0001] The invention belongs to the technical field of artificial propagation of insects, and in particular relates to a method for raising corn aphids suitable for the reproduction of aphid gall midges, and a method for annual artificial propagation of aphid gall midges by using the method. Background technique [0002] Aphidoletes aphidimyza (Rondani) is an insect of Diptera and Ephididae. Its host insects are mainly cotton aphids, which mainly damage cotton and other crops. In my country, Aphidoletes aphidimyza are mainly distributed in Hubei and other regions. Aphid-eating gall midges overwinter as cocooned larvae under the topsoil around the aphid host plant, and pupate in March-April of the following year. After mating, they lay eggs and reproduce on early spring hosts such as weeds with aphids and hibiscus. Every year in early and mid-April is the peak oviposition period of the first-generation adults, and in early and mid-May is the peak oviposition p...
