Rapid and efficient propagation method for neoseiulus barkeri

Abstract

The invention discloses a rapid and efficient propagation method for neoseiulus barkeri. The method comprises the following steps of 1 preparing artificial feed of forage mites, 2 culturing forage mites, 3 performing seed production and culture of neoseiulus barkeri, and 4 performing factorized breeding of neoseiulus barkeri. In this way, according to the rapid and efficient propagation method for neoseiulus barkeri, food mites, which are flour mites and glycyphagus of two different kinds are utilized as common neoseiulus barkeri forage mites to feed neoseiulus barkeri, billions of neoseiulus barkeri can be bred and used as natural enemies on various crops, fruits and vegetables for preventing and treating spider mites, thrips, tarsonemid and the like, the control effect is 90% or above, the pesticide application frequency is lowered by 60% or above annually, the crop yield and number can be increased, ecological environment can be protected, pesticide residues are reduced, and a large number of green foods such as pollution-free grains, vegetables and fruits are produced.

Description

technical field [0001] The invention relates to a breeding technique for thrips, harmful mites and predatory mites, the natural enemies of nematodes, in particular to an artificial high-efficiency and rapid breeding method for Neoseiusius pasterii, including an artificial feed formula and an industrialized production process. Background technique [0002] At present, the occurrence of thrips and harmful mites in various crops is very rampant, coupled with the excessive and high-frequency use of pesticides, many thrips and harmful mites have developed strong drug resistance, which has become a very difficult problem in agriculture. For example, the thrips on the cowpea in Hainan is very severe. In severe cases, the yield of cowpea can be reduced by more than 80%. Farmers are forced to use highly toxic and highly toxic pesticides, causing poisonous cowpea to appear, which seriously damages the vital health interests of the people. Some pest mites are also very harmful to tea g...

Problems solved by technology

Zhang Yanxuan et al.'s "production method for predatory mites" application CN200710008808.4 discloses a method for cultivating acaroid mites and then raising Amblyseius pasteurii. Similarly, simple acaroid mites have no effect on the breeding of Neoseiius pasteurii. good

The breeding method invented and disclosed by Zhang Yanxuan et al. is very ineffective for raising Neoseius pasterii

The reason is that, on the one hand, Neoseiusius mite is omnivorous, and the palatability and nutrition of a single acaroid mite may not be able to fully satisfy its optimal growth state, which is manifested in low reproductive capacity and low population expansion

On the other hand, for the acaroid mites with low reproductive ability such as Tyrophagous scavenging mite, Neoseiusi pasterei has a large food intake, and it is easy to eat up the food of Neoseius pasteruii such as Tyrosinus smoldering mite, and then starve to death. , making it impossible for the population of Neoseiius pasterius to expand

For other acaroid mites, such as A. ellipsoids, although Neoseius ellipsoides can only eat the larvae of A. ellipsoids and cannot eat its adults, Neoseius ellipsoides cannot finish eating A. ellipsoids, but due to Its reproductive ability is low, the population of Neoseiusi pasterii is difficult to expand, the production cycle is long, and the yield is low

Ineffective invention application CN200580052561.5, "A mite composition comprising sweet mite species and phytoseioids" discloses t
