摘　　要：黑色软蚧蚜小蜂为柑桔网纹绵蚧的内寄生蜂。其个体发育包括卵、幼虫、蛹和成虫 4个时期。幼虫的发育分 3个龄期 ,根据颚的大小和虫体的形态可区分各龄幼虫。一龄幼虫两颚较小 ,体节分界不明显 ,可吸食寄主体液 ,二龄至三龄幼虫两颚明显增大 ,身体明显分为 1 3个体节 ,除吮吸寄主体液外 ,还可咬食虫体。幼虫老熟后 ,停止取食 ,排出粪便 ,然后化蛹。成虫羽化后 。Coccophagus yoshidae Nakayama is parasitized in the body of the scale insect host,chloropulvinaria polygonata (Cockerell) and its ontogenesis consists of 4 periods,i.e.,egg,larva,pupae and adult.The larva sucks body fluids and little boby tissue of the host.The larva consist of 13 boby segments.It's cephalic skeleton is ossified and possesses with antennal disks.The thoraci and aldominal segment possesses spiracles.The larvae of third instar excretes fecal materiae,stop feed and pupate.During eclosion the bee pierces the shell and emergence.
