In line with the great instructions of Chairman Mao Zedong on the “struggle against pests and diseases”, under the motto of “Prayers and Bore holes Campaign”, in order to explore the law of Trichogramma against Trichoplusis and carry out mass demonstrations against pests and diseases in our area, The second generation, 10.9 million bumblebee, put the area of 291 acres of bees, the average parasitic rate of 56.5%, the highest parasitic rate of 94.51%, and achieved good results. The experiment is now organized as follows: First, the screening of robust bee species from the local pine forest screening bee species, which is to solve the provenance and selection of robust bee important measures. We are specific
