Method for artificially and massively feeding natural enemy staphylinid

Abstract

The invention relates to a method for artificially and massively feeding natural enemy staphylinid. The method is carried out in an environment with temperature ranging from 18 DEG C to 32 DEG C and relative humidity ranging from 65% to 95%, and tyrophagus putrescentiae and carpoglyphus lactis are used for artificially feeding massive Atheta coriaria and Oligota flavicornis. Feed base materials respectively comprises 35% -65% and 25% -50% of water. Feeding ratio between prey acarus and the natural enemy staphylinid is 50:1-1000:1. The feeding lasts for 20-50 days. When population density of the natural enemy staphylinid is higher than or equal to 400 pcs. / liter, the natural enemy staphylinid can be packaged into finished products or be put into different containers for feeding. The feeding method is simple, highly effective and of low cost and can provide a wide range of natural enemy staphylinid sources for preventing and killing fungus gnat, ephydrid, frankliniella occidentalis, springtails, nematodes, tetranychus truncatus ehara and other pests for purpose of generalizing the biological prevention technologies of China, therefore, the use of chemical pesticides can be reduced, the eco-environment is improved and the international competiveness of agricultural products can be improved.

Description

technical field

[0001] The present invention relates to a method for artificially raising large quantities of Insecta, Coleoptera, Staphylinidae and Athetacoriaria by using tyrophagous mite and sweet fruit mite . technical background

[0002] For a long time, in my country's agricultural production, chemical pesticides have always been the main means of preventing and controlling pests and diseases, seriously affecting my country's ecological environment and human health; "Green Barriers". In order to improve our ecological environment, enhance our physical fitness and the international competitiveness of agricultural products, it is particularly necessary to reduce the use of highly toxic chemical pesticides.

[0003] As early as the 1980s, developed countries in Europe, America and Japan began to implement a package plan to reduce the use of pesticides, and established a technical system centered on biological control. At present, developed countries such as Europe and t...

Embodiment 1

[0023] In an environment with a temperature of 25°C and a relative humidity of 90%, there is a vent in the center of the upper top, the size of which is 1 / 3 of the upper top surface, the height is 6cm, and the bottom area is 20cm 2 In the circular breeding container, put into the mixture of 35% water content, 2cm thick wheat bran and vermiculite (mass ratio 4:1), according to the ratio of 1:100 feeding ratio of paederus paederus and tyrophagous mite Inject 20 paederus japonica and a population density of 1000 heads / g of tyrophager mite and its compost, feed for 40-50 days, and investigate once every 10-20 days. When the ratio of worms is lower than 50:1, puttyrophagous mite and its compost are added. When there are a large number of paederus paederus in the upper surface of the box, it can be packaged as a finished product or reared in separate boxes.
