APHIDIUSforce E for Aphid Control

Aphidius ervi (APHIDIUSforce E) are parasitoid wasps that will attack many common species of aphids. A. ervi attacks "larger" species such as Potato Aphid (Macrosiphum euphorbiae) and Foxglove Aphid (Aulacorthum solani). These are some of the most common pest aphids, but all total, over 40 species are hosts for either A. colemani or A. ervi, or both. As with most biocontrol agents, they are best used as a preventative when aphid levels are either low, or not there at all. However, higher rates of the wasps in conjunction with aphid predators such as Chrysoperla can be used for outbreaks. A. colemani is particularly effective when used with banker plants.Female wasps of both species will sting and inject a single egg inside of an aphid. One female can sting hundreds of aphids in her two-week lifetime, although most of it occurs in the first couple days after her emergence. Once the egg hatches, the larva slowly consumes the aphid from the inside. About a week to 10 days later, the larv
