我国脊虎天牛属幼虫记要(鞘翅目:天牛科)

RECORDS OF THE LARVAE OF SEVEN SPECIES OF XYLOTRECHUS FROM CHINA (COLEOPTERA: CERAMBYCIDAE)

脊虎天牛属(Xylotrechus)幼虫是农林业常见害虫。华东地区老桑园受桑脊虎天牛(X.chinensis Cheyrolat)为害,有的桑园受害株达60—80％,灭字脊虎天牛(咖啡灭字虎天牛)(X.quadripes Chevrolat)是小粒种咖啡毁灭性害虫,广西阳圩农场咖啡树干受害率达60％,整枝枯死的达54.6％,青杨脊虎天牛(X.rusticus(L.))、核桃脊虎天牛(X.contortus Gahan)、葡萄脊虎天牛(X.pyrrhoderus Bates)、巨胸脊虎天牛(X.magnicollis Fairmaire)和北字脊虎天牛(X.atronotatus Pic)等皆为各地经常发生的害虫。 上述各种成虫陈世骧(1958)、蒲富基(1970)、Gressitt(1940,1951)先后有记录,Duffy(1968)简单记录了采集自印度,为害咖啡的灭字脊虎天牛幼虫。
