A-3型松褐天牛引诱剂诱虫谱研究

STUDY ON THE SPECIES OF INSECTS TRAPPED BY A-3 SAWYER BEETLE ATTRACTANT

2002～2004年,在广州地区应用A-3型松褐天牛Monochamus alternatus Hope(鞘翅目Coleoptera天牛科Cerambycidae)引诱剂诱捕鞘翅目昆虫,结果表明：A-3型松褐天牛引诱剂具有较广的诱虫谱,可以诱捕到鞘翅目中10个科48种昆虫；松树的主要蛀干害虫是松褐天牛、赤梗天牛Arhopalus unicolor Ganhan、马尾松角胫象Shirahoshizo patruelis Voss、松瘤象Hyposipalus gigas Fabricius和松纵坑切梢小蠹Tomicus piniperda Linnaeus等小蠹虫；进一步分离所诱捕的松褐天牛及其他松树主要蛀干害虫携带松材线虫Bursaphelenchus xylophilus Nickle的情况,发现松褐天牛与赤梗天牛均携带松材线虫,其中松褐天牛是松材线虫病最重要的传播媒介。

Insects of Coleoptem were trapped by A - 3 sawyer beetle attractant within 2002 - 2004 in Guangzhou. 48 species belong to 10 families of Coleopetera were caught by A - 3 attractant, which indicated that A - 3 attractant had broad spectrum of trapped insects. Principally pine stem - borers are Monochamus alternatus Hope, Arhopalus unicolor （Ganhan）, Shirahoshizo patruelis （Voss）, Hyposipalus gigas （Fabricius） , Tomicus piniperda Linnaeus and other species in Scolytidae. Separating from all the attracted beetles showed that Bursaphelenchus xylophilus was carried by both Monochamus alternatus and Shirahoshizo patruelis, and Monochamns alternatus is the main vector of the pine wood nematode.
