A high-efficiency bee breeding method to improve the balance of the formation of aphids Aphids aphids

Abstract

The invention discloses a high-efficiency bee breeding method for improving the uniformity of the formation of the dead aphids of Aphids cocoon. Aphids are connected to the leaves of the lower part of the wet tobacco plants, and the aphids are allowed to spread and reproduce by themselves. After removing the axillary buds, apply growth inhibitors to continue to suppress the top dominance; step (3) balanced parasitism: when the average amount of aphids on the wet tobacco plants reaches When the value is required, the adult bees without heavy parasitoids are inserted into the cover net, and the cover net is covered with a sunshade net during the bee receiving period; step (4) collects dead aphids. The invention combines the advantages of strong tobacco plant bearing capacity, convenient management and short period of floating tobacco seedlings, and at the same time manages water and fertilizer through the dry-wet alternation method, and cultivates floating wet tobacco plants with strong plants, tender leaves, and aphids' preference for feeding , in the subsequent process of breeding aphids and bees, through the treatment of topping and suppressing buds, the nutrient accumulation in the middle and lower leaves is promoted, so that the aphids can reproduce in a balanced manner on the leaves of each part.

Description

technical field [0001] The invention belongs to the technical field of aphid aphid reproduction, and in particular relates to a high-efficiency bee breeding method for improving the formation balance of aphid aphid. Background technique [0002] Aphids persicae is an important parasitic natural enemy of aphids and other aphids. It has been widely used to control aphids on tobacco and other crops. At this stage, floating tobacco seedlings, ground planting or potted tobacco plants are mainly used to breed bees, which release dead aphid seedlings. Or the way of becoming bees is also difficult to meet the needs of popularization and application. There is an urgent need for long-term refrigeration, convenient transportation and release of aphid products in production. Efficient breeding of neatly developed aphids is a prerequisite for the production of aphids. [0003] The Chinese patent application with the application number 200810187795.6 discloses a method of using tobacco pl...

Problems solved by technology

[0005] Through the comparison test of these two bee breeding methods, it is found that the tobacco plant has a strong bearing capacity, a high bee reproduction rate per plant, and the bred aphids or aphid cocoons are big and strong, but water and fertilizer management is inconvenient, and the bee reproduction per unit area is low , and the breeding cycle is long

The floating tobacco seedling breeding method has weak carrying capacity of the tobacco seedlings, and the stiff aphids or aphid cocoons are relatively weak, but the management of water and fertilizer is convenient, the breeding cycle is short, and the number of bee breeding per unit area is high

In addition, these two methods also have the problem of irregular formation of aphids and inconsistent formation time of aphids on the upper, middle and lower leaves of the tobacco plant, which is inconvenient to collect and spread, especially for the collection of aphids. bigger

[0006] At present, when those skilled in the art are breeding aphids, they are all used in local tobacco fields and other farmlands, and are released in the form of aphid seedlings, aphid leaves or adult bees. The transportation efficiency is low and it is easy to cause A large number of wasps die, and the radiation radius generally rarely exceeds 50 kilometers; the production adopts the "self-use and self-support" and "release as you raise" methods, and does not pay attention to the balance and uniformity of the formation of dead aphids of the aphid.
