The invention belongs to the technical field of
agricultural pest prevention and control, and particularly relates to an
apis cerana sialoprotein RP402 and application thereof. The invention provides the sequence of the salivary
protein RP402 of the point bug and the coding
gene of the salivary
protein RP402, and the RP402
gene is silent in a specific targeting manner through an
RNA (Ribonucleic Acid) interference technology, so that the inhibition of a soybean aging process can be obviously relieved, the
normal aging of leaves is accelerated, and the occurrence of a green symptom phenomenon is reduced, thereby effectively improving the normal
ripening rate and the yield of soybeans. Therefore, the prevention and control method for the Eriomycorus lividus or the prevention and control method for the soybean
disease green provided by the invention has the characteristics of accuracy, high efficiency and
environmental protection, not only makes up for the defects of the existing prevention and control measures, but also reduces the use of chemical pesticides, reduces the environmental
pollution and the risk of pest resistance to drugs, and improves the
economic benefits of the Eriomycorus lividus and the soybean
disease green. Popularization and application of the method can provide powerful guarantee for green and
sustainable development of the soybean industry in China.
