A method for raising white-backed planthopper indoors

Abstract

The invention discloses a method for raising white-backed planthopper indoors. The sponges are placed in hatching bottles and storage boxes respectively, and Kimura culture solution is poured into the sponges to submerge the sponges, and rice seeds are sown on the sponges in the hatching bottles and storage boxes. Above; when the rice seeds in the hatching bottle emerge 2-3cm, insert male and female adults of white-backed planthopper into the hatching bottle in pairs, seal them with gauze and raise them in an artificial incubator until they lay eggs; when the nymphs hatch in the hatching bottle The nymphs are transferred to the storage box, and are also sealed with gauze and raised in the artificial incubator until the nymphs grow up to adults, and then they are inserted into the hatching bottle in pairs to lay eggs, and the cycle is repeated. The density of adults raised in the hatching bottle of the present invention is not high, and the amount of eggs laid is large. After the eggs hatch, it is convenient to remove the newly hatched nymphs from the bottle. The nymphs are moved into the transparent storage box, and after they grow into adults, the adults are inserted into the hatching bottle again, and the cycle is repeated, which can provide a large number of sources of white-backed planthoppers. At the same time, the items used can be reused many times, saving costs.

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
