Wheat aphid and myzus persicae cooperative biological control method based on aphidius gifuensis

Abstract

The invention discloses a wheat aphid and myzus persicae cooperative biological control method based on aphidius gifuensis. The method comprises the following steps that S1, plowing treatment is carried out on a wheat field before wheat planting and sowing, weeds are removed, wheat is sown, and an agricultural compound fertilizer is applied during wheat sowing; wheat seedlings are watered and fertilized at proper time to guarantee normal growth of the wheat seedlings; S2, aphidius gifuensis is released in the wheat field through young stiff aphids, tobacco seedlings which generate a lot of stiff aphids through a floating seedling raising method are used, the young stiff aphids are collected, a matrix on the tobacco seedlings has a good water retention function and can survive for 10 days or longer in the wheat field, and it can be ensured that all the stiff aphids on the tobacco seedlings grow into adults through eclosion. According to the method, the stiff aphids are release before the predicted peak period of wheat aphids, increase of the number of the wheat aphids is effectively controlled, aphidius gifuensis bred from the wheat aphids can be well utilized to prevent wingless aphids of a tobacco field, and wheat aphid and myzus persicae cooperative biological control is achieved.

Description

technical field [0001] The invention relates to the technical field of biological control, in particular to a method for synergistic biological control of wheat aphids and aphids based on Aphids aphids. Background technique [0002] In recent years, people have paid more and more attention to the quality, safety and health of agricultural products, and their awareness of environmental protection has also increased. The control of Aphis persicae on tobacco has achieved great success. However, due to the low temperature in winter and spring in the northern tobacco area, the lowest temperature is below minus 10 degrees Celsius. Higher, to a large extent, limits the popularization and application of this technology, so how to reduce the breeding cost of Aphidia persicae, and obtain a larger number of A. Significance, therefore, it is necessary to design a collaborative biological control method for wheat aphids and aphids based on Aphids aphids. Contents of the invention [...
