Large-scale breeding method for anagrus nilaparvatae

Abstract

The invention relates to the technical field of insect feeding, and discloses a large-scale breeding method for anagrus nilaparvatae. The large-scale breeding method comprises the following steps that 1, rice seedlings in a seedling stage are cultivated; 2, rice seedling pots obtained in the step 1 are moved into a first insect breeding cage placed in a brown planthopper inoculation and culture room, brown planthopper adults with the female-male ratio being 1 to 1 are inoculated into the first insect breeding cage, and rice seedling pots with brown planthopper eggs are produced; 3, the rice seedling pot with brown planthopper eggs obtained in the step 2 are transferred into a bee-keeping cage, and anagrus nilaparvatae with a male-female ratio of 1 to (0.5-1) is inoculated into the bee-keeping cage; and 4, bee pupae are collected, specifically, the rice seedlings with anagrus nilaparvatae in a pre-pupal stage are put into a refrigerator at 4 DEG C for cold storage, and adult bees are collected. According to the large-scale breeding method for the anagrus nilaparvatae, large-batch and continuous production of the anagrus nilaparvatae can be achieved, and the adult anagrus nilaparvatae can be rapidly obtained to prevent and control rice planthoppers by refrigerating and storing the rice seedlings with the anagrus nilaparvatae in the pre-pupal stage.

Description

technical field [0001] The invention relates to the technical field of insect feeding, in particular to a large-scale breeding method of the rice lice wasp. Background technique [0002] Rice lice (Anagrus nilaparvatae Pang et Wang) are widely distributed in major rice producing areas in my country, and are migratory pests of rice planthoppers (there are three main types of planthoppers that damage rice: brown planthopper (Nilaparvata lugensStal), white-backed planthopper (Sogatella furcifera Horvath) and white-backed planthopper (Laodelphax striatellus Fallén), among which brown planthopper occurs and causes the most damage, followed by white-backed planthopper). However, the outbreak of the rice planthopper population is sudden and devastating, and the peak period of the rice planthopper in the field is obviously lagging behind the large-scale occurrence period of the rice planthopper, so that when the rice planthopper outbreak, the rice planthopper ( parasitic wasps) cann...

However, the outbreak of the rice planthopper population is sudden and devastating, and the peak period of the rice planthopper in the field is obviously lagging behind the large-scale occurrence period of the rice planthopper, so that when the rice planthopper outbreak, the rice planthopper ( parasitic wasps) cannot effectively control rice planthoppers
