摘要
2000-2005年对黄河滩区东亚飞蝗Locusta migratoria manilensis（Meyen）天敌种类普查,调查结果显示,东亚飞蝗天敌104种,隶属6纲23目43科,优势种9种。评价了天敌对东亚飞蝗的控制作用,优势种为中国雏蜂虻Anastoechus chinensis Paramonow,在发生区内,对卵块寄生率为22.4%-56.5%,一般年份寄食率为36%。星豹蛛Pardosa astrigera L.Koch在蜘蛛类天敌中占50%-70%,是蝗蝻期的重要天敌。发现不同植被覆盖度内的飞蝗天敌群落和数量有明显的差异。
The natural enemies of Locusta migratoria manilensis （Meyen） in the Yellow River beach of Shandong Province were investigated during from 2000 to 2005. A total of 104 species belong to 6 classes , 23 orders, and 43 families. Among them 9 are dominant species.
