Embodiment 1

[0028] A large-scale breeding method of thrips thips, comprising the following steps:

[0029] (1) Selection of peanut leaves: after the flower grows more than 5 compound leaves, select large and thick mature peanut leaves, clean the surface, and dry for later use;

[0030] (2) Insertion of Tetranychus urticae: insert 8 pinches of peanut leaves on the sponge soaked in water in the tray, and evenly connect the Tetranychus urticae at the early stage of oviposition on the peanut leaves, 40 per pinch, Under the condition of temperature 28~32℃, relative humidity 75%~85%, and light 10~14 hours a day, Tetranychus urticae reproduced for 10 days;

[0031] (3) Reproduction of Tetranychus urticae: Divide each pinch of leaves after the initial breeding into 4 groups, mix 6 new leaves for every 2 leaves and then continue breeding for 4 days, then divide each pinch of leaves into 3 groups: ① Among them After adding 6 new leaves to 2 leaves, continue to propagate Tetranychus urticae, and th...

Embodiment 2

[0038] A large-scale breeding method of thrips thips, comprising the following steps:

[0039] (1) Selection of peanut leaves: after the flower grows more than 5 compound leaves, select large and thick mature peanut leaves, clean the surface, and dry for later use;

[0040] (2) Insertion of Tetranychus cinnabarinus: insert 8 pinches of peanut leaves on the thick 2cm sponge soaked in water in the tray, keep a distance between the pinches to prevent mutual transmission of Tetranychus cinnabarinus; Tetranychus urticae were evenly attached to the peanut leaves, 40 heads per pinch, and reproduced for 10 days at a temperature of 30°C, a relative humidity of 80%, and 12 hours of light per day;

[0041] (3) Propagation of Tetranychus cinnabarinus: Divide each pinch of leaves after the initial reproduction into 4 groups, mix 6 new leaves for every 2 leaves and then continue to reproduce for 4 days, and then divide each pinch of leaves into 3 groups: ① Among them, 2 Add 6 new leaves to...

Embodiment 3

[0048] After the large-scale breeding of thrips at the six-point tower is stable, the step of spider mite inoculation is not required: taking the operation of raising 100 boxes of products a day by a worker as an example, it can be implemented in the following steps:

[0049] (1) Cut 1,400 peanut leaves from the field, wash off the dust and dry the leaf surface for later use;

[0050] (2) Divide 600 leaves into 100 parts, mix 2 leaves with mites for every 6 leaves and insert them on the sponge to continue to propagate Tetranychus urticae for 4 days;

[0051] (3) Divide 800 leaves into 100 parts, mix 4 leaves with mites for every 8 leaves and insert them on the sponge to continue to propagate spider mites for 4 days;

[0052] (4) Insert 200 leaves covered with two-spotted spider mites that have been inserted on the sponge for 4 days every morning into the tower six-spotted thrips spawning hood (about 14 leaves that have been laying eggs for 7 days) The group needs to newly ins...

Abstract

The invention belongs to the field of insect cultivation and specifically relates to a scale breeding method of Scolothrips takahashii. The method includes peanut leaf selection, tetranychidae introducing, tetranychidae breeding, Scolothrips takahashii female imago introducing, Scolothrips takahashii female imago spawning, spawn collection and preservation, nymph development, preservation of 3rd instar nymphs. The scale breeding method is an imitating ecotype breeding method and is simple in production process, low in material costs and high in production efficiencies; the scale breeding method has a standardized operation procedure, and circulation supply of thrips foodstuffs can be achieved through one-time tetranychidae introducing; the obtained Scolothrips takahashii is orderly in developmental duration, high in rates of survival, high in activity and high in operability in application when the Scolothrips takahashii is used as natural enemy products; compared with general acaricide, the Scolothrips takahashii has the advantages of being small in labor intensity, high in efficiencies and good in control effects of tetranychidae and can not pollute the environment; and obtained agricultural products are free of pesticide residuals, and the Scolothrips takahashii can be widely applied to prevention of the tetranychidae in the field and has broad market prospects and obvious economic benefits.

Description

technical field [0001] The invention belongs to the field of insect breeding, and in particular relates to a method for large-scale breeding of thrips thipscens. Background technique [0002] The spider mite tetranychid mite; spider mite is a herbivorous mite, which harms cotton, fruit trees, vegetables, forest trees and ornamental plants, and is an important agricultural pest. Spider mites live by sucking the cell fluid of leaves, which seriously affects the photosynthesis of plants. Today's most important control method is spraying acaricides. However, due to the short generation period of spider mites, strong fecundity, and easy resistance, although there are endless types of acaricides and the dosage is higher, in recent years, mite infestation There is an increasing trend. Analyzing the reasons, one-sided reliance on chemical acaricides leads to the shortage of natural enemies of spider mites, resulting in the loss of natural enemies' natural control over spider mites...
