Embodiment Construction

[0006] Embodiments of the present invention are as follows: take tussah silkworm cocoons, use a blade to cut out an incision of the size of a soybean grain, and select the ones with live pupae; pack 30 gnawing peaks into the cocoon according to the number of gnawing small peaks in one cocoon, and then put the gnawing bee species into the cocoon. The tussah silkworm cocoon is placed in a carton with a temperature of 18-28°C and a relative humidity of 60-80%, and the parasitic bee emergence of the small peak is completed through an effective accumulated temperature of 370°C.

Abstract

A technique for breeding a kind of wasp (tiny psocid wasp) with tussah pupa includes cutting open the tussah cocoon, selecting the cocoon containing living pupa, putting the wasp seeds in it, and laying aside at 18-28 deg.C and 60-80% humidity until the grown-up wasp comes out. Its advantages are quick and unified breeding speed, high survival rate. Said wasp is used to prevent and eliminate American Hyphantria.

Description

technical field [0001] The invention relates to the technical field of biological control of agricultural, forestry and sanitary pests. Background technique [0002] So far, the damage caused by pests against agricultural and forestry plants and sanitary pests is very huge, and pests such as corn borer, cotton bollworm, American white moth, red pine caterpillar, Chinese pine caterpillar, elm poisonous moth, flies and other pests have a great impact on food. Yield and quality are also greatly affected, which reduces the nutritional value of people's food. Due to the continuous use of chemical pesticides in large quantities for many years, food products such as food, vegetables, and fruits are seriously polluted. With the development of modern science and technology, there has been a lot of progress in the research and application of high-tech management of agricultural, forestry and sanitary pests, such as the protection and utilization of natural enemy insects, artificial ma...
