| Abstract: | Under laboratory conditions, when reared onPhorodon humuli aphid,Adalia bipunctata deposited 1011 ova and mean longevity of males and females was 55–73 days respectively. When reared onAphis fabae orA. fabae + Aphis craccivora diet, females ofA. pipunctata deposited 41–63 ova, and mean longevity of males and females was 20–32 days respectively. Larvae reared onP. humuli completed development in average 8.9 days, and mortality was 16.7%. Larvae reared onA. fabae, orA. fabae + A. craccivora aphids, completed development in 14–15 days, and mortality was 83–90%. It is concluded thatP. humuli aphid is an essential food forA. bipunctata, whereasA. fabae andA. craccivora aphids, are unsuitable foods. |
