| Abstract: | The suitability of thirteen aphid species for the polyphagous larvae ofMetasyrphus corollae (Fabr.) was investigated in laboratory tests. The length of larval and pupal development, weight of puparia, mortality during larval and pupal stages were compared. Cannibalism was not observed in the larvae reared in groups on suitable food.Aphis sambuci Linneaus was not a suitable prey for the larvae.Cavariella theobaldi (Gillette Bragg) collected fromPastinaca sativa L. was toxic to larvae ofM. corollae, although it was possible to rear the larvae onAphis fabae Scopoli orAnuraphis subterranea (Walker) from the same host plant. |
