母生(Homalium hainanense Gagnep)是海南岛的主要珍贵用材树种之一。解放后,全岛已相继营造了母生人工纯林约5万多亩,其中很多已成片郁闭或成林。随着林木的成长,现在各地的母生均遭受了母生小木虱(Aphalara sp.)不同程度的为害,严重地影响母生的生长。为及时防治,确保林木的正常生长,现将1964—1965年的研究结果,整理如下,以供各地防治参考。 Mother (Homalium hainanense Gagnep) is one of the major tree species of Hainan Island. After the liberation, the island has successively created about 50,000 mu of mother plantation pure forests, many of which have become stagnant or forested. With the growth of trees, all the mother and daughter are now affected by different degrees of Aphalara sp., Seriously affecting their growth. In order to timely control and ensure the normal growth of trees, the results of the study from 1964 to 1965 are summarized as follows for reference.
