Abstract

The invention provides a brown planthopper carbonic anhydrase (CA) gene segment and application thereof. The sequence of a brown planthopper CA gene is shown as SEQ ID No.1, and the sequence of dsRNA is shown as SEQ ID No.2. The gene can be used for inhibiting brown planthoppers from growth so as to control the survival rate of the brown planthoppers. The gene can be transferred in rice, so as to research the biological influence of transgenic rice on the brown planthoppers. Therefore, the invention provides a new efficient path for continuously preventing and controlling brown planthoppers.

Description

technical field

[0001] The present invention relates to the field of biotechnology. It specifically relates to the brown planthopper CA gene fragment and its dsRNA and the application of the dsRNA to lethal brown planthopper. Background technique

[0002] Brown planthopper ( ) Brownplanthopper (BPH) belongs to Hemiptera (Hemiptera), planthopper family (Delphacidae). Oligophagous pests can only complete normal development and life cycle on rice (Oryza sativa L.) and common wild rice under natural conditions (Sogawa1982; Wu Guorui et al., 1987). It is an important pest on rice crops in my country. The brown planthopper is an oligophagous pest. It causes serious damage to rice through the following ways: 1. Direct piercing and sucking damage. Both adults and nymphs suck rice tissue juice with piercing-sucking mouthparts, It absorbs plant nutrients, affects the normal growth of rice, slows plant growth and reduces yield. When the rice plants are severely damaged, they even f...
