Problems solved by technology

Although the research results show that sweet fruit mite is more suitable for large-scale rearing of A. szeidei compared with A. ellipsoides, it is not only costly and labor intensive to raise s. The mite's competitive ability is weak, and it is easy to be polluted and replaced by other acaroid mites during the breeding process

Embodiment 1

[0021] The raising method of embodiment 1 insectivorous mite

[0022] 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 a circular breeding container, put wheat bran with a height of 3 cm and a water content of 15 to 35%, and then insert 1,000 insectivorous mite mite species, which can be used for raising Seiseienius microbes after 10 days.

Embodiment 2

[0023] The rearing method of embodiment 2 Seiseius sternii

[0024] 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 Put a mixture of wheat bran and vermiculite (mass ratio 3:1) with a water content of 15% to 35% and a thickness of 3 cm in a circular breeding container, and the feeding ratio of Seiseius sternii and Stenophora stenophora was 1:50. Inject 100 heads of Seiseius sternii and Entomophagocytic mite at a certain ratio, and raise them for 20 days, and the number of them can reach more than 2,000.

Abstract

The invention relates to a method for manually feeding Typhlodromips swirskii massively with Thyreophagus entomophagus. The method comprises the following steps of: performing deinsectization and sterilization on a feed container under the environment of the temperature of between 18 and 32 DEG C and the relative humidity of 65 to 100 percent; feeding the Thyreophagus entomophagus with Thyreophagus entomophagus feed; and inoculating two kinds of mites according to the ratio of the Thyreophagus entomophagus to the Typhlodromips swirskii of 15-150:1 into the feed container containing a feed basic material of the Typhlodromips swirskii so as to massively feed the Typhlodromips swirskii after 15 to 30 days. The method has the advantages of simpleness, low price and good effect. Compared with hesperidium mites, the Thyreophagus entomophagus is more suitable for massively feeding the Typhlodromips swirskii. The fed Typhlodromips swirskii can provide a large number of predatory mite resources for preventing and controlling Chinese bemisia tabaci gennadius and western frankliniella intonsa, so that the using amount of chemical pesticide is reduced and the output and the quality of agricultural products are improved.

Description

technical field [0001] The present invention relates to a breeding method of Thyreophagus entomophagus and a method for raising Typhlodromips swirskii technical background [0002] Whitefly (Bemisia tabaci) and western flower thrips (Frankliniella occidentalis) are important and dangerous pests in the world. B-type Bemisia tabaci is the only pest in the world currently called "super pest". These two pests not only directly suck the plant juice, but also cause the host plant to lose green and water, affect photosynthesis and the accumulation of crop nutrients. Moreover, they can all transmit plant virus diseases and cause devastating damage to various crops such as vegetables and flowers. [0003] Both are small juice-sucking pests that multiply and mutate quickly, and are prone to resistance to chemical pesticides, which makes chemical control both enter a vicious circle—the amount and concentration of use are constantly increasing. Not only uneconomical, but also lead to...
