Abstract

The invention discloses an application and a product of dsRNA in potato beetle control, and relates to an application of a gene product in potato beetle control and a derivative product. The dsRNA product has strong stability, mature production technology and low cost, and is an effective cheap 'gene pesticide' product with strong specificity, green and environmental protection. The application ofthe dsRNA product in potato beetle control has great and far-reaching significance in potato beetle control. After a potato beetle pesticide is sprayed on leaves of potato plants at a low dose, the potted potato plants can continuously resist insects for more than 28 days, and the control effect reaches more than 80%; and under the outdoor strong ultraviolet condition, the potato beetle pesticidestill has a strong poisoning effect on potato beetles, the field prevention and control lasting period is about 3 weeks, and the prevention and control effect is gradually reduced from 50% to about 10%.

Description

technical field [0001] The invention relates to the application of a gene product in the control of potato beetle and its derivative product. Background technique [0002] Potato is an important grain, vegetable, feed crop and industrial raw material crop in the world. In recent years, due to its obvious comparative economic benefits and other characteristics, the planting area in my country has continued to increase, and it has become the first in my country after rice, wheat and corn. 4 major staple food crops. The potato beetle, Leptinotarsa ​​decemlineata, also known as the potato beetle, its English name Colorado Potato Beetle (CPB), belongs to the order Coleoptera and the family Chrysolithidae. It is recognized as a destructive pest of potatoes in the world, and it is also one of the major quarantine targets in my country. Its host range is relatively narrow, and it mainly harms more than 20 species of Solanaceae plants such as potatoes, eggplants, cultivated tomatoes,...
