Problems solved by technology

[0004] The key technical point of the present invention not only solves the problem of the vitality degradation of the long-term large-scale breeding population of Neoseius bifidus from the feeding link, but also improves the control ability of Neoseius bistheii to the target pests

Embodiment 1

[0038] Embodiment 1: Insert 50 Neoseiidus bifidus (raised by Tetranychus Turkestan) preserved in step S1 into a sufficient amount of Tyrophagous saprophagae and carry out a large number of multiplication in the breeding device. The population of the microsei mite increased by 5000 times. Then, 2,500 target pests of Thrips occidentalis were put into the population of Neoseius bitailensis to adapt to Thrips occidentalis for 1 day. Finally, the Neoseius bifidus was released to the strawberry in the greenhouse to control the target pest Thrips occidentalis on the strawberry plants thereon.

Embodiment 2

[0039] Example 2: Insert 200 Neoseius bifidus (raised with Tetranychus Turkestan) preserved in step S1 into a sufficient amount of Tyrosophora saproscens bran matrix for a large number of multiplication, and after 14 days, the neoseius bitails The population of small seiusius mite can increase by 6000 times. Subsequently, 10,000 target pests, Turkestan Tetranychus, were put into the population of Neoseius bitailensis to adapt to Turkestan Tetranychus for 2 days. Finally, Neoseius bitail was released in the cotton field to control the target pest Turkestan spider mite on it.

Embodiment 3

[0040] Embodiment 3: Compared with the above, the difference is that there is an additional step S3 / 4 between steps S3 and S4: use a separation device to purify and separate Neoseius bitailae before putting it into the field, and the separation device can be a common one on the market. Predator mite separation device.

Abstract

The invention discloses a breeding method for improving the quality of Neoseiulus bicaudus. The breeding method includes the breeding steps: S1 breeding the Neoseiulus bicaudus by Tetranychus turkestani and performing breed conservation; S2 breeding the Neoseiulus bicaudus by Tyrophagus putrescentiae and performing extensive expanding propagation; S3 performing target pre-adaptation on the Neoseiulus bicaudus before release; S4 throwing target adapted Neoseiulus bicaudus populations in the S3 into a field. Target pests include any or combination of two or more of spider mites, thrips and whiteflies. The breeding problems of breed conservation and extensive expanding propagation of the Neoseiulus bicaudus are solved, target adaptation can be performed on the Neoseiulus bicaudus according tobiological control requirements of actually thrown crops, selection and preference of the Neoseiulus bicaudus are correctly guided, recognition of the spider mites, the thrips or the whiteflies by the Neoseiulus bicaudus is facilitated, the population vitality and the predation capacity of the Neoseiulus bicaudus can be screened by target adaptation, and the quality of the Neoseiulus bicaudus populations to be thrown for biological control can be improved.

Description

technical field [0001] The invention belongs to the technical field of biological control, and in particular relates to a breeding method for improving the quality of Neoseiius bifidus. Background technique [0002] Neoseiulus bicaudus (Wainstein, 1962) is a new record species of predatory mite found in Xinjiang in recent years. It has a good predation effect on many kinds of spider mites, thrips and whitefly. Neoseius two-tailed mite can also adapt to the dry and hot climate in Xinjiang, and is suitable for various crops such as cotton, kidney bean, strawberry, eggplant, etc. It is a very potential biological control of predatory mites. At present, the artificial propagation of Neoseius two-tailed mite is usually raised by substituting the prey Tyrosophagus saprophytum. This method is low in cost and large in production, but long-term breeding will cause the size of Neoseius two-tailed mite to become smaller and the selection preference will change, causing The feeding hab...
