The application discloses a dsRNA targeting
phosphoenolpyruvate carboxykinase gene PEPCK and application of the dsRNA in prevention and control of spider mites, and relates to the technical field of
genetic engineering. The technical points are as follows: the
nucleotide sequence of the dsRNA targeting
phosphoenolpyruvate carboxykinase gene PEPCK is shown in SEQ ID NO:1, and the dsRNA can be used for preventing and controlling spider mites or preparing products for preventing and controlling spider mites. The dsRNA targeting
phosphoenolpyruvate carboxykinase gene PEPCK provided in the application has a high lethal effect on female adult spider mites, can effectively control the
population number of spider mites, and reduces the field damage of spider mites. The dsRNA can be used for development of transgenic
mite-resistant plants or novel
mite-killing agents, can be used for targeted resistance to specific types of mites, does not affect other
beneficial insects and organisms, and can improve the
mite resistance of plants.
