Embodiment Construction

[0015] The present invention will be further described below by specific examples.

[0016] A low-density breeding method for maintaining the wingless state of the pea aphid parthenosexual, specifically comprising the following steps:

[0017] (1) Broad bean planting: Soak the broad bean seeds in warm water for 12 hours, and set aside; mix the Northeast black soil and vermiculite at a volume ratio of 1:2, add water and stir evenly, and move it into a flowerpot to lay flat, and put the broad bean seeds Insert it into the cultivation soil, water until the substrate in the flower pot is soaked, place it under the condition of light of 16L:8D, temperature of 28°C, and humidity of 60%, and water once every two days;

[0018] (2) Seedling transplantation and inoculation: 7-8 days after sowing, when the broad bean grows to 5-8cm, that is, when two true leaves are unfolded, move the broad bean plant into a plastic cup, cut a small hole in the filter paper, and make the broad bean stem...

Abstract

The invention discloses a low-density breeding method capable of maintaining a wingless state of acyrthosiphon pisum viviparous female. The low-density breeding method includes the steps of planting of broad beans, cultivation of aphids, group experiments, observation and data recording. The low-density breeding method has the advantages of simple operation, stable state, no seasoning restrictionand the like, materials for studying a wing-shaped differentiation mechanism of aphids are provided, and a good foundation is laid for studying the aphid pest control.

Description

technical field [0001] The invention belongs to the field of disease and insect pest control, and in particular relates to a low-density breeding method for maintaining the wingless state of parthenogenes of the pea aphid. Background technique [0002] Pea aphid, also known as pea bearded aphid and pea aphid, belongs to the genus Aphididae of Hemiptera, and is one of the main pests on leguminous plants. The pea aphid is a worldwide pest and was first reported in England in 1776. In the United States, pea aphids cost alfalfa producers approximately more than $60 million per year. In Northwest my country, due to the influence of alfalfa pests, 10-30% of economic losses are caused every year, and aphids are the most important species of damage. Pea aphids often cause damage by clustering adults and nymphs on tender stems, leaves, flowers and pods. Pea aphids usually have two peaks in a year, spring and autumn, and occasionally in mid-summer. [0003] Pea aphids are particul...
