Development of predator oenopia conglobata and parasitoid aphidius colemani fed on aphis fabae

Aphids are polyphagous pests that cause significant damage to many cultivated plants. Aphids have many natural enemies. These are birds, Syrphidae larvae, Coccinellidae adult and larvae, earwigs, parasitoits and entomopathogens. One of the most important aphid species in agricultural areas is Aphis fabae (Hemiptera: Aphididae). In this study, the activities of Oenopia conglobata (Coleoptera: Coccinellidae), one of the most important predators of aphids, and Aphidius colemani (Hymenoptera: Braconidae), one of their parasites, on A. fabae were discussed. As a result, egg, first larval, second larval, third larval, forth larval, pupal and adult durations of O. conglobata fed on A. fabae were calculated as 5.00, 3.60, 2.67, 2.83, 2.93, 4.97 and 11.75 days, respectively. It was observed that A. colemani not development on A. fabae.
