    Abstract

    The parasitoid Aphidius gifuensis is able to parasitize both the green peach aphid Myzus persicae and the foxglove aphid Aulacorthum solani in sweet pepper. In a greenhouse experiment we showed that rates of parasitism on green peach aphids alone were equal to the commonly used Aphidius colemani, but lower than with Aphidius matricariae. Foxglove aphids were suppressed very effectively by A. gifuensis. In contrast, A. matricariae was not able to parasitize this aphid. When the two aphid species were offered simultaneously, A. gifuensis suppressed both aphid species, whereas the presence of foxglove aphids had a negative effect on the control of green peach aphids by A. matricariae. We conclude that A. gifuensis is a promising candidate for biological control of both foxglove aphids and green peach aphids in sweet pepper, especially when these aphids occur together.
