Survey of Longicorn Species in Pinus koraiensis Plantation in Dongning City,Heilongjiang Province
In orde r to investigate the population regularity of different species of Longurus in the Pinus koraiensis plantation in Dongning City,this study used traps to investigate the species and quantity of Longurus in the red pine plantation in Shuangqiaozi Forest and Erdaogang Forest in Dongning City from June to September 2023.The results showed that a total of eight species of Longicornis in three subfamilies were caught in this survey,among which the largest numbers were Monochamus saltuarius Gebler and M.russovi Fisher.The first capture was on June 26 with seven,and the last was on August 28 with only three.The trapping of spruce rhinocornis peaked on July 3,when 72 animals were caught that day,and has since declined.Through the investigation of the species and quantity of the longan in this area,the eclosion law of the local longan was mastered effectively,which provided a theoretical basis for the prevention and control of harmful longan.
