Field release method of glyphodes pyloalis parasitic wasps

Abstract

The invention discloses a field release method of glyphodes pyloalis parasitic wasps. The method comprises the following steps: collecting aulacocentrum confusum adults, taking every 667m<2> of a mulberry field as a release unit, setting a release point in the center of each mu of the mulberry field, outwards extending 3-5 radiation lines from the release point to the boundary of the mulberry field, and setting a group of release points on the radiation lines, wherein the release number of the parasitic wasps at the central release point is 50-100, and the release number of the parasitic wasps at each position of the release points on the radiation lines is 50-75. When the method is used for releasing the aulacocentrum confusum in the field, the parasitic efficiency of the aulacocentrum confusum on the glyphodes pyloalis is high, the pest control effect is remarkable, the natural and continuous pest control capacity of the aulacocentrum confusum is high, and population growth of the third generation and the fourth generation of the glyphodes pyloalis can be stressed. The method is simple and convenient to operate and low in release cost, solves the problem of field release of the glyphodes pyloalis parasitic natural enemies, is beneficial to fully exerting the natural pest control effect of the glyphodes pyloalis parasitic natural enemies, improves the control effect on the glyphodes pyloalis, reduces the application quantity of chemical pesticides in the mulberry field, and ensures the growth safety of silkworms and the environmental safety of the mulberry field.

Description

Technical field

[0001] The invention belongs to the field of biological prevention and treatment of agricultural pests, and it is related to the field release method of mulberry benefits parasitic bee mix chamber. Background technique

[0002] Glyphodes Pyloalis is a baren wingletum LEPIDOPTERA, moth of Slim Pyralida, is a major pest in my country, especially 3, 4 generations of mulberry, it is easy to enabling disaster, which will cause significant damage to mulberry production in a short time. It is endangered by autumn breeding. Mulberry warechable mulberry leaves and mulberry buds, should have strong disaster capacity, once the climate conditions are suitable, the population can achieve rapid growth in the short term. In addition, there is a significant generation overlap phenomenon in the mulberry species, which gives more difficulties. In addition, the feces of the mulberrhea, the feces discharged after the mulberry leaves are easily contaminated, causing the quality of mul...
