Preliminary Study on High-efficient Propagation of Trichogramma evanescens by Corcyra cephalonica Egg
By inoculating Trichogramma evanescens into the eggs of Corcyra cephalonica in the laboratory,we studied the parasitism and eclosion rates of T.evanescens under different devices and inoculation times.The results showed that the parasitism rate of T.evanescens in the finger-shaped tube was significantly higher than in other devices,by which the maximum magnification was six times.There was no significant difference in par-asitism rate between 1-hour,2-hour,4-hour,and 8-hour inoculation,as well as eclosion rate.
