摘  要：
连续3年对广东省西江林业局直属9个林场的马尾松林分设立标准地进行松突圆蚧的虫情调查,同时调查胸径生长情况。结果表明:被调查标准地所在的高要、德庆、云城、新兴、云安、郁南等区县均为松突圆蚧发生区;各标准地因受害时间及危害程度不同,造成虫口密度有极显著差异;不同龄组的马尾松均受到松突圆蚧的危害,同一时期,林龄越大,虫口密度越大;除通门林场外,其他各标准地由于受到松突圆蚧的危害,森林资源增长缓慢。建议将西江林业局受松突圆蚧危害的马尾松林纳入广东省林分改造工程建设范畴,间伐或皆伐后套种或全面更新阔叶树种,从根本上遏制松突圆蚧的虫情升级和蔓延。

摘  要：
The sample plots of Pinus massoniana stand in nine forest farms which are subordinate to Xijiang Forestry Bureau of Guangdong Province were set.For 3 consecutive years,the pest situation of Hemiberlesia pitysophila in the sample plots was investigated,at the same time the growth of diameter at breast height was also surveyed.The results showed that: Gaoyao,Deqing,Yuncheng,Xinxing,Yunan and Yunan districts were occurring areas of H.pitysophila.Because of the differences of harmful time and harmful degree among the sample plots,the population density was extremely different from among them significantly.The different age groups of P.massoniana were all subject to H.pitysophila's damage.During the same period,the population density increased with the increase of stand age.Except for that from Tongmen forest farm,the forest resources of the other sample plots grew slowly because of H.pitysophila's damage.It was suggested that the P.massoniana stand damaged by H.pitysophila should be incorporated into the construction areas of stand transformation project in Guangdong Province.After thinning or clear-cutting,some broad-leaved species should be intercropped or full updated,then the trend of ascending and spread of pest situation of H.pitysophila would be suppressed radically.
