A kind of method and application of vegetable seedlings for propagating Aphids aphids

Abstract

The invention provides a method for cultivating aphidius gifuensises using vegetable sprouts and the application thereof, and belongs to the technical field of insect cultivating and biological insect control. In the method, aphidius gifuensis are bred using vegetable sprouts, a bactericide and supplementing nutrients are sprayed according to the growth conditions of the aphidius gifuensis, a cultivating net is adopted, the aphidius gifuensises are taken out according to the activity routine, so that the effect of myzus persicae control is better. The period of the aphidius gifuensis cultivation is shortened to about 50 days, 160 thousands of zombie myzus persicaes and parasitic myzus persicaes are achieved at each square meter. Sowing and cultivating tobacco sprouts are needless, only vegetable sprouts need sowing, the management is easy, labor saving and time saving. The method can fully use present device to breed aphidius gifuensises, the investment of facilitates for cultivating aphidius gifuensises can be reduced, and the cost for cultivating aphidius gifuensises can be reduced. The method has been tested in large-scale aphidius gifuensis cultivation, the time efficiency, the unit area efficiency, the management efficiency and the like of large-scale aphidius gifuensis cultivation are raised, and the cost of aphidius gifuensis cultivation is greatly reduced.

Description

technical field [0001] The invention relates to a method for propagating Aphids aphids by vegetable seedlings and its application, especially for cultivating neat and strong vegetable seedlings with suitable density for breeding aphids, timely inoculating adult bees or stiff aphid leaves, and vegetable seedlings for breeding bees under the condition of a net room The method, and the application of the Aphids persicae to tobacco leaf planting belong to the technical field of insect feeding and pest biological control. Background technique [0002] The tobacco aphid is one of the main pests in the production process of tobacco leaves. By sucking the nutrients of the tobacco plant, the nutrition of the plant is deteriorated, affecting the normal growth and development of the plant. It will affect the normal photosynthesis of plants and induce mildew. Aphids are the transmission medium of various viruses, spreading viruses, causing the epidemic of plant virus diseases, and serio...

Problems solved by technology

[0002] The tobacco aphid is one of the main pests in the production process of tobacco leaves. By sucking the nutrients of the tobacco plant, the nutrition of the plant is deteriorated, affecting the normal growth and development of the plant. It will affect the normal photosynthesis of plants and induce mildew. Aphids are the transmission medium of various viruses, spreading viruses, causing the epidemic of plant virus diseases, and seriously affecting the quality and yield of tobacco leaves.

There are agricultural control, chemical control, physical control and natural enemy control methods for the control of aphids. For a long time, people mainly rely on the use of chemical insecticides for chemical control. The resistance of aphids continues to increase, which seriously affects the safety of tobacco leaves.

[0003] Aphids persicae is a dominant parasitic wasp of A. persicae and an important parasitic natural enemy of A. persicae. This bee species is widely distributed and has a high parasitic rate to A. persicae. It is applied to control aphids in tobacco and vegetable crops, and the control effect is remarkable. At present, the technology of using Aphidia persicae to control aphids has a long breeding cycle and low efficiency, and the duration of effective control of aphids is short. Collecting and releasing Aphisias persicae is laborious and costly.
