摘要
目的为常德市德山公园的白蚁防治提供科学的理论依据和实践指导。方法采用普查和抽查相结合的方式对德山公园5大区域的池塘边、过道、山脚、山腰、山顶的树木以及林地枯枝、枯桩、伐桩进行白蚁采集和危害调查。结果德山公园白蚁危害的优势种为黄胸散白蚁,其占比大且分布广,占整个调查地白蚁危害数量的65.71%。共调查树木4 846棵,黄胸散白蚁危害树木共1 067棵,其中过道两侧的树木危害最为严重,危害率高达44.80%。黄胸散白蚁对树木根部的危害程度大于茎部和枝干,总危害率达到54.55%。樟树、茶树、杉树、松树不同程度地受到了黄胸散白蚁的危害,分别达到了43.48%、29.51%、16.82%、10.46%。结论掌握了常德德山公园5大地域树木白蚁分布和危害状况,为开展德山公园以及周边园林苗圃的白蚁危害综合治理提供了理论依据。
Objective To provide some basic data for controlling the trees damage from termites in Deshan Park.Methods Sampling with general investigation,through collecting the termite specimens in the five areas of Deshan Park,including the trees near the pool,passage way,the foot of the hill,the top of the hill and the hillsides. Results The dominant species of termites in Deshan Park was Reticulitermes flaviceps,accounting for 65. 71% of the total number of termites surveyed. There were 1 067 trunks damaged by Reticulitermes flaviceps out of 4 846 trunks surveyed. The 44. 80% damage rate occurred on these trees near the sides of passenger beyond the damage rates of other areas. The root damage rate by Reticulitermes flaviceps was 54. 55%,much more than those of the stem and the limb. In those varieties of tree surveyed,Cinnamomum camphora was most seriously damaged by termites with the damage rate 43. 48%,followed by Camellia oleifera（ 29. 51%）,Cunninghamia lanceolata（ 16. 82%）,and Pinu parvifloras（10. 46%）. Conclusion The results of the termite distribution and damage to trees in Deshan Park in this investigation could provide a basic data for further termite control in Deshan Park.
