A BIOLOGICAL STUDY ON BLASTIPETROV A KETELEERIACOLA LIU ET WU(LEPIDOPTERA:TORTRICIDAE) WITH DESCRIPTIONS OF A NEW GEHUS AND NEW SPECIES

    摘要
  • 摘要: 云南油杉(Keteleeria evelyniana Mast.)为我国特有种,产于云南、贵州西部及西南部、四川西部及西南部,生长在海拔700-2600米的温暖红土地带,耐干燥气候,对土壤要求不严,能适应干旱瘠薄的立地条件。它的木材坚韧,纹理直行,结构细致,硬度中等,易于加工,干燥时不易开裂,富含树脂,耐浸溃。

     

    Abstract: Blastipetrova keteleeriacola Liu et Wu is described as new to science;and Blastipetrova Liu et Wu is a new genus of Eucosmini(Olethreutinae).The new genus is closely related to Petrova Heinr.and Blastesthia Obr.They are clearly distinguishable from the venation and the genitalia.In the fore wing of Petrova,M2 and M3 separate at base,while in Blastipetrova,they are approximated or connate,Blastesthia is with only one signum,while Blastipetrova is with two.This pest causes considerable loss of seed to Keteleeria evelyniana Mast,in the central region of Yunnan Province.In this paper,the taxonomy,bionomic,natural enetmies and suggestion of control methods are given.
