Adult bee collecting method of aphidius gifuensis bred in arch shed

Abstract

The invention relates to an adult bee collecting method of aphidius gifuensis bred in an arch shed. According to the method, an insect prevention net (5) is integrally covered outside a shed frame of the arch shed, a shade net (6) is covered at the arch top of the arch shed, the top of the phototropic surface of the arc shed is provided with at least one bee collecting hole (8), a detachable bee collecting bag (2) is connected outside the bee collecting hole, the negative geotropism and the phototaxis of the aphidius gifuensis are utilized, adult bees of the aphidius gifuensis bred and survived in the arch shed are collected into the bee collecting bag (2). The adult bee collecting method has the characteristics that the characteristic of aphidius gifuensis bred in a small shed is combined, the negative geotropism, the phototaxis habit and the activity peak time of the aphidius gifuensis are utilized, the bee collecting bag is used for collecting adult bees for releasing in fields, the dying of adult bees in the shed before field loose keeping is prevented, and the adult bees are effectively utilized.

Description

technical field [0001] The invention relates to a method for collecting adult bees that emerge when aphids aphids is bred in an arch shed, which is used in the technical field of biological control of agricultural pests. Background technique [0002] The use of Aphids persicae to control Aphids can effectively control the harm of Aphids, reduce the use of chemical pesticides, improve the safety of tobacco leaves, and at the same time have important significance for protecting the ecological environment. For this reason, the tobacco planting industry has begun to study and promote Aphids Cocoon bee artificial breeding technology. At present, the technology of artificial bee breeding is mainly to use the small shed to float seedlings to breed the Aphididae, and then release the Aphidias to the field after collecting them. But this method is not easy to collect into bees. For this reason, people also adopt small sheds to breed the Aphids aphids and release them in the field m...

AI Technical Summary

Problems solved by technology

When using a small shed to breed Aphids aphids, some adult bees will emerge in the shed before the aphid seedlings are released in the field. If these adult bees are not collected and released in time, they will die in the shed and cannot be used effectively.

Therefore, some people use bee extractors to collect adult bees, but they cause greater damage to the Aphididae in the shed, reducing the survival rate and parasitism rate of the Aphidia in the field.

There has been no effective method of collecting adult bees
