不同琼脂配比对阿里山潜蝇茧蜂寄生效果的影响

Effects of agar to water ratio on the parasite efficiency of Fopius arisanus

阿里山潜蝇茧蜂是实蝇的一种卵—蛹跨期寄生蜂。研究人工产卵盘中琼脂与水的比例对该蜂寄生效果的影响。结果表明,阿里山潜蝇茧蜂的寄生率随产卵盘中琼脂含量的增加而增加,当琼脂与水的比例增至1∶50,其寄生率趋于稳定。对2007年4月至2008年9月产卵盘改进前后阿里山潜蝇茧蜂的出蜂率进行了比较,改进前、后平均出蜂率由37.5%提高至61.0%。

Fopius arisanus is an egg-pupal parasitoid of Tephridae. Effect of agar to water ratio on the parasite rate of F. arisanus was studied. The results showed that the parasite rate of F. arisanus increased with the increasing of agar ratio and reached a plateau at 1： 50. Room rearing of F. arisanus from April 2007 to September 2008 was recorded. The percentage of parasitoids recovery increased from 37.5% to 61.0% after oviposition dish bettered.
