摘要
倍林内肚倍蚜（KaburagiarhusicolaTaKagi．）虫口密度的高低，直接影响肚倍产量。根据肚倍蚜的生态生物学习性，在倍林内构筑5种不同小生境栽植冬寄主美灰藓[Eurohypnumleptothallum（C．Muell．）Ando．]，接种肚倍夏迁蚜，培育过夏越冬若蚜，提高林内倍蚜密度。45．5亩试验林，肚倍单产平均达28．5Kg，比对照高6．0倍。
The population density of gallnut phids, Kaburagia rhusicola Takagi, has much to do with production of Chinese gallnut. This paper deals mainly with the ecological adaptation of Du -aphids, Kaburagia rh usicola Takagi. The moss, Eurohypnum leptothallum (C. Muell. )Ando., was growm on five different artificial habitats, V -- type ditch, terraced platform, slope of 45 degree, high bed and wood plates, in the woodland; the summer migrants were inoculated on to the moss in different habitats to rear overwinter ing nymphs,increased the plpulation density in the plantation. The experiment has been made in aplantation of 3. 03ha, the unit yields amounting 427. 5kg on the average, which is 6. 0 times as much as the contrast.
