Method for rearing sogatella furcifera indoors

Abstract

The invention discloses a method for rearing sogatella furcifera indoors. Sponges are laid in a hatching jar and a container respectively, Kimura culture solution is poured into the hatching jar and the container and immerses the sponges, rice seeds are sowed on the sponges in the hatching jar and the container, adult sogatella furcifera is led into the hatching jar in a female and male paired manner, sealed in a manual incubator by gauze and reared until spawning when the rice seeds in the hatching jar sprout by 2-3cm, nymphs are transferred into the container, similarly sealed in the manual incubator by the gauze and reared until growing into adults when hatched in the hatching jar, the adults are led into the hatching jar in the paired manner again and spawn, and the process is repeated. The adults reared in the hatching jar are low in density and large in spawning quantity. After hatching, newly-hatched nymphs in the jar are conveniently removed. The nymphs are transferred into a transparent storage box, the adults are led into the hatching jar again after growing into the adults, and the process is repeated, so that a large quantity of sogatella furcifera pest sources can be provided. Besides, used articles can be repeatedly used, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of raising insects for agricultural pest experiments, in particular to a method for raising white-backed planthoppers indoors. Background technique [0002] White-backed planthopper, scientific name: Sogatella furcifera (Horváth), Homoptera, planthopper family, alias fire midge, fire spin, is a long-distance migratory pest, one of the most serious pests on rice. The damage methods are as follows: ① A large number of insect populations directly suck rice juice, resulting in a large loss of nutrients and water in rice plants. The damaged rice fields often appear "yellow ponds", "topping" and "lice burns" in the field first, and gradually expand into pieces. Even the whole field withered. ② It can also spread a variety of rice virus diseases and cause indirect damage. In addition, a large amount of honeydew will be discharged during the feeding process, and the leaves covered with honeydew often breed a lar...

Problems solved by technology

Sometimes the damage caused by indirect damage is far greater than the damage caused by direct piercing and sucking. The vicious viral disease rice southern black-streaked dwarf disease with white-backed planthopper as the main vector has expanded its occurrence area in South China, Jiangnan and Southwest rice regions in recent years. , the degree of harm is aggravating, which will cause great losses to my country's rice production
