Investigation on Species of Main Host Trees of Longicorn and Its Prevention and Control in Coastal Protection Forest in Cixi of Zhejiang Province
[Objective]The aim was to investigate the species of trees damaged by longicorn in coastal protection forest of Cixi and study the control methods of longihorn.[Method]In 2009,the field investigation was carried out in the main protection forest engineering area,urban green space and Cixi forest farm in Cixi,the list of host tree species of longicorn was sorted out,and the tree species seriously damaged were listed.From 2021 to 2022,supplementary investigation and data improvement were made on the host tree species of longicorn.[Result]According to field investigation,there were 73 species of host trees of longicorn in coastal protection forest in Cixi of Zhejiang province,among which 17 species were seriously damaged.After 3 years of comprehensive prevention and control,the average larval rate of longicorn in forest decreased from 35.70%to 16.40%.The population density of longicorn in forest decreased from 1153.5 to 529.5 per hectare,with a drop of 54.10%.[Conclusion]The comprehensive application of insecticide control,artificial killing and lure and concentration control with trapping trees are beneficial to improve the control efficiency.
