Abstract: This paper deals with evaluation of the mass propagation system of Aphidoletes aphidimyza using life table. It was showed that high mortalities in the stages of egg(13.5%),1st instar larvae (18.2%) and pupae (19.0%) were the main factors influencing the growth of the experimental population. Abnormal sex ratio caused by the propagation of many successive generations also resulted in reducing viability of the experimental population.These results suggest that the existing propagation system needs to be improved.

Key words: Aphidoletes aphidimyza, experimental population, life table, mass propagation
