金龟子类是防护林带的最顽强的大敌,在辽宁省彰武县北,章古台固沙林带里,以青銅金龟子(Anomola albopilosa Hope)为害最严重,1958年在成虫出现的最高峯(7月10日),一株5—6年生的榆树(Ulmus pumila)上最多可以有成虫200余只。成虫食性极杂,对小叶杨(Populus slmonii)、小青杨(P.pseudo-simonii)、山杏(Armeniaca sibirica)、黄菠蘿(Phellodendron Amurense)、花曲柳(Fraxinus americana)等都能为害,并且食量也大,通常喜欢羣集在树梢上食害嫩叶,所以受害严重的植株常常形成秃梢。
Beetles are the most stubborn enemies of shelterbelts. They were most severely damaged by Anomola albopilosa Hope in the Zhanggu station sand belt in the north of Zhangwu County, Liaoning Province. In 1958, the highest peak appeared in adults On the 10th, Ulmus pumila, a 5-6 year old, can have up to 200 adult worms. Adults have very dietary infertility and can be harmful to Populus slmonii, P. pseudo-simonii, Armeniaca sibirica, Phellodendron Amurense, Fraxinus americana, And food intake is also large, usually like to cluster in the treetops on the damage of young leaves, so severely damaged plants often form bald.
