摘　　要：华中黑头三节叶蜂(Arge huazhongia Wei)是发生在苦水玫瑰上的新害虫,在兰州市一年发生2代,主要以幼虫群集取食玫瑰叶片,雌成虫选择苦水玫瑰健壮的当年生新枝顶部产卵,老熟幼虫在玫瑰根际落叶及虫粪间结茧越冬,次年5月中下旬越冬态成虫羽化。植株受害率达81.4%,当年生新梢受害率30.6%。Arge huazhongia is a new insect pest on the Kushui rose in Lanzhou, with two generations a year. The larvae gather and feed on the leaves of rose. Female adults lay eggs at the top of the young strong branches on the Kushui rose. The mature larvae cocoon and then overwinter in the rhizosphere of rose fallen leaves and frass, and emerge into adults in mid or late May next year. The damage rate of rose plants reaches 81.4%, and that of young sprouts reaches 30.6%.
