Embodiment Construction

[0013] Embodiments of the present invention: the artificial breeding method of Neoseius californica, set up mutually isolated plant cultivation chambers, prey breeding chambers and predatory mite breeding chambers, prey breeding chambers and predatory mite breeding chambers are isolated with water tanks around the chamber; in each chamber Place a self-controlled constant temperature glass incubator, keep the temperature at 25°C±1°C, humidity 40%-50%, and light cycle 16L:8D; put trays on the glass incubator, place 16 incubators on each tray, and spread in the incubator A culture medium with a thickness of 6-7cm; then cultivate cowpea in the incubator, specifically, wash the cowpea seeds with running water for 10 minutes, soak them in alcohol for 30 seconds, rinse them twice with distilled water, and then soak them in 0.1% arsenic and mercury for 8-10 minutes. Rinse with distilled water three times, sow 5 to 8 cowpea seeds in each incubator at a depth of 1 to 2 cm, keep the mediu...

Abstract

The invention relates to a large-scale artificial breeding method for Neoseiulu californicus of a drought-resistant strain. The method comprises the following steps of establishing a plant culture room, a prey breeding room and a predatory mite breeding room which are isolated from one another; placing a self-control constant-temperature glass incubator in each room; keeping the temperature at 25+ / -1 DEG C, the relative humidity of 40 to 50 percent, and the photoperiod of 16L:8D, and placing trays in the incubators; placing 16 culture devices in each tray; paving a culture medium with the thickness of 5 to 7 cm in each culture device; culturing prey host plants in the glass incubator in the plant culture room; taking each prey host plant after germinating and growing the first compound leaf for later use; moving the cultured prey host plants into the prey breeding room, and inoculating tetranychus turkestani for breeding preys; after the prey host plants are inoculated with the tetranychus turkestani for about 15 days, moving the culture trays into the predatory mite breeding room for breeding the Neoseiulu californicus; and after the Neoseiulu californicus is inoculated for 10 to 15 days, collecting the Neoseiulu californicus. By the method, the long-term supply of the Neoseiulu californicus can be ensured.

Description

technical field [0001] The invention belongs to the field of biological control of agricultural pests; more specifically, the invention relates to a method for large-scale artificial breeding of a drought-tolerant strain of Neoseiius californica. technical background [0002] Neoseiulu californicus (McGregor) belongs to Acari subclass Acari, Phytoseii-Dae Phytoseii-Dae, Neoseiulu genus Neoseiulu, its natural populations are widely distributed in Argentina, Chile, California, Florida, Texas Sri Lanka, Japan, South Africa, southern Europe and the Mediterranean coast. It inhabits a wide variety of crops, such as avocados, citrus and other fruit trees, as well as cassava, corn, grapes, herbaceous plants, some vegetable crops and ornamental plants, and is a species that has a strong natural control effect on harmful mites important natural enemy. [0003] Neoseius californica has a wide range of predation and can prey on a variety of harmful mites, mainly including: Tetranychus...
