摘要
研究结果表明:在荔枝龙眼落花收果后,荔蝽卵平腹小蜂迁移到荔枝树附近的开花植物——朱瑾上。9月下旬至10月下旬在朱瑾上挂放人工卵卡,卵块寄生率达50～70%,卵粒寄生率在20%以上;11月上旬仍有一定的寄生率;该蜂向周围迁移的范围较小。
The result showed that egg parasitoid Anastatus japponicus moved to flowering plant Hibiscus rasa——sininsis L. near hitch chinensis after the fruit of L. chinensis and Euphoria longan were picked. The egg cards made from eggs of Antherea pernyi were placed on H.rosa——sinensis, from the last ten——day period of September to the correspnding period of October, the rate of parasitized of egg masses attained 50—70% and that of eggs parasitized was higher than 20%. A few eggs were parasitized in the first ten——day period of November. The moving range of this parasitic wasp is very small.
