From December 27 to December 29, 1990, the Department of Science and Technology of the Ministry of Forestry presided over the appraisal meeting on the application of the comprehensive management of pine caterpillars and the application of trichogramma. The appraisal projects include “Integrated Management of Dendrolimus punctatus in Genotypes 2 to 3”, “ ~ 4 generations of type Dendrolimus punctatus integrated management technology research ”,“ Trichogramma control Dendrolimus punctatus research. ” “Study on the Integrated Management of Masson Pine Caterpillar in Genotypes 2 ~ 3” was co-chaired by Forest Research Institute of China Academy of Forestry and Anhui Province Forest Disease and Pest Control Terminus, and consisted of 14 sub-topics. Is based on ecology, using systematic analysis of the methods, the implementation of a comprehensive management of pine caterpillars. Based on the data of pine caterpillars over the years, 567 mu of experimental forests in Anqing, Anhui Province were divided into different types. On this basis, according to
