Embodiment Construction

[0061] Trichogramma pupae whose pupal state was pre-pupal state were selected as an alternative host.

[0062] From the beginning of October to the beginning of April of the next year, collect the branches harmed by Cypermus cerevisiae on Poplar or Beijing poplar, dissect out the larvae of Cypermus cerevisiae, and place them in small boxes, each box packing 100-150 grams, Then store it at 3-10°C until use. Pick the yellow powder armor that has just pupaed. The pupae are concentrated and stored at 1-10°C for later use.

[0063] From the end of October to November of each year, the adult beetles of Shuangtiaoshan beetle are dissected and stored for 3-months and then used in early February of the following year. Transfer the preserved adult beetles to the bait wood, and insert 8-16 adult beetle beetles into each wood segment, wherein the male and female ratio of beetle beetle adults is 1:0.8-2. 25-70 days after the adult beetle is released, the larvae of the longhorn beetle ar...

Abstract

The present invention discloses a method for breeding Pymeotes scolyti on a large scale and its application method for biologically controlling injurious insects. Said invention selects and uses trichogramma pupa, sulphur pupa, cathay poplar cerambycidae larva and Semanotus bifasciatus (Motschulsky) lana as substitute host and adopts the culture dish and dactylethrae to breed Pymeotes scolyti.

Description

Technical field: [0001] The invention relates to the breeding and application of biological natural enemies of pests, in particular to a large-scale breeding method of Pymeotes scolyti and its application in pest biological control. Background technique: [0002] At present, there are mainly two methods for the control of pests that seriously endanger the growth and development of trees. One is to spray chemical insecticides to poison and kill insects. As the resistance of pests increases, the effectiveness of insecticides drops sharply, resulting in ineffective insecticides. At the same time, all pesticides are toxic and will inevitably pollute the environment. Another method is to use biological control methods to eliminate pests through the mutual restriction relationship between species and use the biological natural enemies of pests. This method is not only non-polluting to the environment, but also has high selectivity and low cost. It is a pest control method that i...
