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 Neoseius two-tailed mite, which adopts the following feeding steps: S1: using Turkestan spider mite to raise Neoseius two-tailed mite for species conservation; S2: using corrosive tyrosid mite to raise two-tailed mite Neoseius mites undergo a large number of multiplication; S3: target pre-adaptation before the release of Neoseius bifidus, wherein the target pests are any one or a combination of two or more of spider mites, thrips and whitefly, S4: The N. two-tailed mite population adapted to the target in S3 is released in the field; the present invention not only solves the breeding problems of N. two-tailed mite species conservation and large-scale expansion, but also can be based on the actual needs of crop biological control. The mite performs target adaptation, so as to correctly guide the selection preferences of Neoseius two-tailed mite, which is conducive to its identification of spider mites, thrips or whitefly, and target adaptation can also improve the population vitality and predation ability of N. Screening is beneficial to improve the quality of the population of Neoseius bitailus to be released for biological control.

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...
