槐尺蠖(Semiothisa cinerearia Bremer et Grey)是国槐(Sophora aponica L.)的主要害虫,在我国分布很广,以往发生数量不大,危害不严重。自本世纪五十年代,在天津、北京、西安等大城市某些街道和庭园中,槐尺蠖幼虫常猖獗大发生,将整株大树或成片苗木的叶片全部吃光。推测是由于这些地方不适当的施用化学药剂防治的后果。为提供对此害虫综合防治对策的基础资料,1985～1987年间作者等对天津市未经化学防治的槐树上槐尺蠖天敌种类和寄生率进行了调查,发现尺蠖凹眼姬蜂(Casinaria sp.)是槐尺蠖幼虫的优势寄生性天敌。在控制其发生数量上起着重要作用。鉴于国内外有关槐尺蠖天敌研究报道甚少,现将所得结果整理如下,供参考。
Semiothisa cinerearia Bremer et Gray is a major pest of Sophora aponica L. It is widely distributed in our country and has not occurred in a large amount in the past and its harm is not serious. Since the fifties of this century, in some streets and gardens of big cities such as Tianjin, Beijing and Xi’an, the larvae of Sophora japonica often flourish and all the leaves of the whole plant or the seedling seedlings are eaten. Presumably due to improper application of chemical control in these places the consequences. In order to provide the basic information for this pest integrated control strategy, from 1985 to 1987, the authors investigated the species and parasitism rate of Caragana anguillae without chemical control in Tianjin, and found that Casinaria sp. ) Is the dominant parasitic natural enemies of Sophora japonica larvae. In controlling the number of occurrence plays an important role. In view of the domestic and international research reports on the natural enemy of Sophora japonica L. little, the results are summarized below, for reference.
