摘要:
 为完善云南省寻甸县害虫预测预报数据，并为防治林业有害生物提供科学的依据，采用路线调查法、查迹调查法和样地调查法调查华山松和云南松主要害虫的地理分布与危害程度。结果表明，在调查的12个乡镇中，有3个乡镇未发现害虫危害华山松，1个乡镇未发现危害云南松。危害华山松的害虫主要有萧氏松茎象（Hylobitelus xiaoi）、松梢斑螟（Dioryctria splendidella）、华山松木蠹象（Pissodes punctatus）、华山松球蚜（Pineus armandicola）；其中萧氏松茎象（H.xiaoi）的危害最严重，主要危害根部，受害株率为1%~87%，分布在海拔1 923~2 249 m，海拔高差326 m。危害云南松的害虫主要有云南切梢小蠹（Tomicus yunnanensis）、楚雄腮扁叶蜂（Cephalica chuxiongnica）、松墨天牛（Monochamus alternatus）、云南松毛虫（Dendrolimus houi），其中云南切梢小蠹（T.yunnanensis）的危害最严重，主要危害干部、梢部，受害株率为1%~43%，死亡株率在1%~17%，分布在海拔1 909~2 350 m，海拔高差441 m。
Abstract:
 In order to improve the ability of pest forecast and to provide scientific basis for the prevention and control of forest pests,the geographical distribution and damage extents of Pinus armandii and P.yunnanensis occurring in Xundian County of Yunnan Province,China were surveyed through the methods of route survey,trace identification and sample plot investigation.The investigation results have practical value in economic production and life.The results showed that among the 12 towns in Xundian County,pests of P.armandii were found in 9 towns and not found in 3 towns,the main forest pests were Hylobitelus xiaoi,Dioryctria splendidella,Pissodes punctatus,Pineus armandicola.The H.xiaoi was more serious among the four main forest pests which fed on the roots and cadre connection part of the P.armandii,the vertical distribution ranged between 1 923 m and 2 249 m,the rate of damaged plants ranged from 1%-87%.Pests of P.yunnanensis have were found in 11 towns and not found in 1 town,the main forest pests were Tomicus yunnanensis,Cephalica chuxiongnica,Monochamus alternatus,Dendrolimus houi.The T.yunnanensis was more serious among the four main forest pests which fed on the cadre and tip parts of the P.yunnanensis,the vertical distribution ranged between 1 909 m and 2 350 m,the rate of damaged plants ranged from 1%-43%,the mortality rate was between 1%-17%.
