Chrysopa septempunctata was fed with two foodstuffs, aphids and artificial ovum Trichogramma's pupas. The results indicated that survival time of female worms which intook aphids was obviously longer compared with those which intook artificial ovum Trichogramma's pupas, and their ovum quantity obviously rose. But artificial ovum Trichogramma's pupas can be used as supplementary foodstuff to raise green lacewing because of its factory production.

The results showed that the aphids were either restrained or promoted when they fed on different treatment crops, compared with the control not fed by aphids and the corresponding treatment previously fed by different aphid species. S. avenae restrained the growth of S. graminum (MRGR=0.0974±0.0071) on 98-10-30, but S. graminum promoted the growth of S. avenae (MRGR=0.1614±0.0048) on 98-10-30. Penetrations of aphids promoted the growth of S. avenae on Amigo, while promoted growth of S. graminum on Batis.
