Problems solved by technology

Taking the temperature of 16°C as an example, the immature period of the sword-haired handkerchief is as high as 38 days. The multiplication of mites; and when the sword hair mite feeds on putrefactive tyrophagous mite at 32 ℃, the sword hair mite that develops from eggs to female adults cannot lay eggs, so it cannot multiply, let alone the temperature is higher than at 32°C

Embodiment 1

[0020] Example 1 See Table 1 for the amount of predation of Parlelea lanceolata in a 24°C, 100% RH fresh-keeping box to adult tyrophagous mite

[0021] It can be seen from Table 1 that female, male, and nymphs of P. sapiens can prey on adults of Tyrophagous sarcoptera; the predation amount of female adults is the largest, followed by nymphs, and male adults are the least.

[0022] Table 1 The predation amount of Paleopsis swordhair mite on adults of Tyrophagous mite

Embodiment 225

[0024] Example 225 ° C, 100% RH conditions under the conditions of sweet fruit mite and tyrophagous tyrophagous on the growth and reproduction of Paleopsis sword hair.

[0025] 1) See Table 2 for the effects of two prey species on the immature stage of each mite stage of P. It can be seen from Table 2 that, feeding on sweet fruit mite and tyrophagous tyrophagous mite, Paleopsis swordhair mite can complete the growth and development of the immature stage.

[0026] 2) See Table 3 for the effects of sweet fruit mite and tyrophagous mite on the maturity and lifespan of female adults of P. It can be seen from Table 3 that the adult female mite of the two prey mite mite P.

[0027] 3) See Table 4 for the number of eggs laid by sweet fruit mite and tyrophagous mite under the two reproductive modes of female adult mite of P. It can be seen from Table 4 that under the two prey conditions, the female adult mite of the sword hair handkerchief can lay more than 50 eggs in a lifetime.

Embodiment 3

[0034] Example 3 Effects of sweet fruit mite on the growth, development and reproduction of Paleopsis sword-hair mite under different temperature and 100% RH conditions.

[0035] 1) See Table 5 for the developmental stages of each adult female mite. The immature stage of female adult mite was the longest at 16°C, and the female adult mite did not lay eggs at 32°C.

[0036] 2) See Table 6 for the developmental stages of each mite stage of male adult mites. The male adult mite of the sword-haired handkerchief was the longest at 16°C, followed by 32°C.

[0037] 3) See Table 7 for the survival rate of Paleopsis swordhair mite from egg development to adult mite stage. The survival rate of the immature stage of the sword-hair mite can reach more than 90% at 20°C-28°C, the highest at 24°C, and the lowest at 32°C. The immature stage survives with the increase of temperature at 16°C-24°C. The survival rate increased gradually; at 24°C-32°C, the survival rate decreased with the increa...

Abstract

The invention relates to a method for breeding a large amount of Stratiolaelaps scimitus and Hypoaspis aculeifer (Canestrini) manually, which is a method for breeding a large amount of the two kinds of predatory mites manually by using prey mites in a medium such as sphagnum moss and peat soil in an environment at the temperature of 18 to 30 DEG C and a relative humidity of 65 to 95 percent. The method comprises: placing the breeding medium in a breeding container; inoculating the prey mites and predatory mites in the breeding container according to a ratio ranging from 10:1 to 1,000:1; and breeding for 15 to 45 days to obtain the large amount of Stratiolaelaps scimitus and Hypoaspis aculeifer (Canestrini). In the invention, the method breeds the two kinds of predatory mites with the medium with high water retaining performance and loose texture; and the method with more desirable breeding effect, simpler operation, lower workload and longer storage period in the breeding container is the optimal method for breeding the two kinds of predatory mites commercially. The method can provide more effective predatory mite resources for the small-scale biological prevention and control of harmful sciarid fly, rhizoglyphus robini claparede, flour mites, nematode and the like in crops such as greenhouse crops and edible fungi.

Description

technical field [0001] The invention relates to a method for producing Stratiolaelaps scimitus and Hypoaspis aculeifer by artificial mass rearing of prey mites. 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 plant diseases and insect pests, seriously affecting my country's ecological environment and human health. In recent years, the export of my country's agricultural products has been blocked one after another, which is mainly related to the "green barriers" that foreign countries have increased the detection of pesticide residues. 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 ...
