马尾松干蚧(Matsucoccus massonianae Y·H·R·)为松蚧属(同翅目珠蚧科)的一个新种。1973年秋首先在宁波市郊和鄞县天童林场育王林区的马尾松林中发现。以后台州、舟山等地区的马尾松林中也相继发现。它以若虫寄生于松树树干或树冠下部枝条的大枝干皮层缝隙内,吸食树液。被害的植株轻则树势衰弱、生长缓慢,严重的引起树冠下部枝条下垂,针叶枯黄并导致小蠹虫等次期害虫的侵入,以致整枝枯死。 1974年以来,我们在宁波地区鄞县天童林场育王林区,对马尾松干蚧的发生规律及其防治措施,作了一些观察和试验,现将初步结果整理如下:
Matsucoccus massonianae Y.H.R. is a new species of the genus Conus (Homoptera). The fall of 1973 first in the suburbs of Ningbo and Yinxian Tian Tonglin Yu Wang Lin district found in the masson pine. After Taizhou, Zhoushan and other areas of Massive pine forest have also been found. It nymphs parasitic in pine trunks or branches of the lower branches of the branches of the trunk cortex gap, taking tree liquid. Plants were damaged from light trees rather weak, slow growth, causing severe drooping branches of the lower part of the canopy, yellow leaves and brouha yellow led to the invasion of pests and other secondary pests, resulting in pruning dead. Since 1974, we have made some observations and experiments on the occurrence and control measures of Masson pine scale in Yuwanglin District, Tiancong Forest Farm, Yin County, Ningbo. The preliminary results are summarized as follows:
