Abstract: This study evaluated the parasitism of cotton aphids Aphis gossypii Glover, Acyrthosiphon gossypii Mordvilko, and Aphis craccivora Koch by Binodoxys communis Gahan in Xinjiang cotton fields, as well as the effectiveness of host species and instars on the development duration and reproductive capacity of B. communis. Our results showed that, except Ac. gossypii, both A. gossypii and A. craccivora were hosts of B. communis, and B. communis preferred to parasitize A. gossypii. The younger instar A. gossypii and A. craccivora were parasitized more than the older instar nymphs and adults. Once parasitized, different instars of the same aphid species had no significant effect on the growth and development of the offspring of B. communis. Our study has identified the preferred host species and instars of cotton aphids by B. communis, and provided a scientific basis for utilizing B. communis for biological control of aphids in Xinjiang cotton fields.

Key words: Aphis gossypii, Aphis craccivora, Binodoxys communis, host-stage selection
