不同防治措施对樟子松林松毛虫防治效果的影响

Effects of Different Control Measures on the Control of Dendrolimus sp.in Pinus sylvestris var.mongolica Forest

松毛虫(Dendrolimus sp.)是中国森林发生面积最大的食叶害虫。为了更好地对松毛虫进行防治,筛选出经济、高效、实用的防治措施,选取昌图县付家林场4块标准地,在早春通过采用绑胶带、毒绳等措施进行松毛虫防治试验。结果表明:使用胶带、毒纸绳和毒麻绳3种材料阻隔松毛虫上树数量有显著性差异(P<0.05),防治效果依次为毒麻绳>毒纸绳>胶带,以用胶带防治效果最差;不同部位绑2圈毒纸绳处理和绑1圈毒麻绳处理是防治松毛虫效果最好的2种方法。综合防治成本因素,建议在昌图县使用绑1圈毒麻绳处理的方法防治松毛虫。

Dendrolimus sp.is the largest leaf-eating pest in China.In order to better control Dendrolimus sp.and&screen out economical,efficient and practical control measures,selected four standard plots in Fujia Mechanical Forest Farm to conduct Dendrolimus sp.control trials in early spring by adopting tape binding and poison ropes.Result shows that there are significant differences in the number of trees blocked by Dendrolimus sp.using three materials,tape,poison paper rope and poison hemp rope(P<0.05),the order of prevention and control effect is:poisonous hemp rope>toxic paper rope>adhesive tape.Explain that the tape has the worst effect to control pine caterpillar.The treatment of tying two loops of poisonous paper rope and the treatment of one loop of poisonous hemp rope at different locations are the two optimal methods of prevention&treatment.Based on the cost of prevention&control,it is recommended to use a method of tying a loop of poisonous hemp rope to prevent&control Dendrolimus sp.in this area.
