摘    要:在中国首次发现并记述了桔小实蝇寄生蜂印度实蝇姬小蜂Aceratoneuromyia indica(Silvestri),该蜂隶属膜翅目姬小蜂科啮小蜂亚科。研究标本保存于广东省农业科学院植物保护研究所。同时在温度25℃、RH75%、光周期L:D=16h:8h的条件下,研究了印度实蝇姬小蜂对桔小实蝇幼虫的寄生功能反应。结果表明:桔小实蝇幼虫的密度变化对印度实蝇姬小蜂的寄生作用有很大影响,可用功能反应HollingⅡ模型模拟,其模拟方程为Na=0.2528N0/(1+ 0.0090N0)。通过该方程可明确一头印度实蝇姬小蜂在24h内最多可寄生28.24头桔小实蝇幼虫;其寄生一头寄主幼虫所需的时间为0.85h。印度实蝇姬小蜂成虫的自身密度对寄生也有干扰作用,其干扰作用符合Hassell-Varley模型,拟合方程为a=0.0556P^-0.2427。

关 键 词:新记录  中国  桔小实蝇  印度实蝇姬小蜂  寄生效能

Abstract:A new species of parasitoid, Aceratoneuromyia indica (Silvestri) (Hymenoptera: Eulophidae: Tetrastichinae) for Bactrocera dorsalis (Hendel) was recorded in China. The specimens were kept in Plant Protection Institute, Guangdong Academy of Agricultural Sciences. Its parasitism efficiency on larvae of B. dorsalis was investigated at 25℃, 75% RH and photoperiod of L:D = 16 h:8 h. The result showed that the larval density of B. clorsalis significantly affected the wasp' s parasitism efficiency, which could be described by the equation of Holling Ⅱ , Na = 0. 2528N0/(1 + 0.0090N0). Daily maximum parasitizing numbers of B. dorsalis larvae by A. indica was 28.2, and the time for parasitizing one larva was 0.85 h. The density of A. indica also affected its parasitism, which could be described by the equation of Hassell-Varley, α = 0.0556P^-0.2427.
Keywords:new record  China  Bactrocera dorsalis  Aceratoneuromyia indica  parasitical efficiency
