Problems solved by technology

Pests and diseases occur side by side, resulting in severe reduction in peanut production
At present, the control of peanut aphids mainly depends on chemical insecticides. However, chemical control often brings a series of problems such as environmental pollution, increased insect resistance and rampant pests.

Abstract

The invention relates to the technical field of prevention and control over crop diseases and pests, in particular to an ecological regulation and control method of peanut aphids. Corn is planted around peanuts, predators of the peanut aphids are nourished and cultured through the corn, and then through the ecological regulation and control effect of the natural enemies to the peanut aphids, the purpose of controlling pests and increasing yield in a green and efficient manner is achieved. The corn serves as the auxiliary crop, corn plants are easy to obtain and also relatively simple in planting, the required economic cost and management cost are not high, and popularization of the method is facilitated.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of crop diseases and insect pests, and in particular relates to an ecological control method for peanut aphids. Background technique [0002] Peanut is a bulk oil crop and is widely planted in China. At the same time, my country is also the largest consumer and exporter of peanut. Peanut aphid is one of the important pests that damage peanuts. This kind of pest is widely distributed in the main peanut producing areas of my country. Usually, adults and nymphs gather on the buds, leaves and fruit needles of peanuts, which often cause leaf curls. Shrinkage, yellowing, slow plant growth, and even fruit needles cannot be needled, affecting the number and development of pods; in addition, peanut aphids can also transmit peanut stripe virus (PStV) and peanut mottle virus (PMoV). Pests and diseases occurred side by side, resulting in a severe reduction in peanut production. At present, the...
