Larvae of Syrphus ribesii (L.) appearred to be the most voracious. It was found that predator-prey ratio from 1:25 to 1:50 was the most effective at Episyrphus ba/teat us (Deg.) and Sphaerophoria scripta (L.) larvae in Aphis fabae control on broad bean.}, type={Article}, title={The effectiveness of aphidophagous syrphid larvae (Diptera, Syrphidae) in the control of Aphis fabae Scop.
