This mix contains an even split 50/50 of two species of parasitoid wasps, Aphidius colemani and Aphidius ervi. This mix is very effective for targeting a wide range of aphid species, with Aphidius colemani particularly effective against round bodied aphid species, such as the melon or cotton aphid (Aphis gossypii), peach aphid (Myzus persicae) and tobacco aphid (Myzus nicotianae). Aphidius ervi is specifically for the larger elliptical shaped species including Macrosiphum euphorbiae (potato aphid), and Aulacorthum solani (glasshouse potato aphid).

| Tech Comments | Most crops can be infested with aphids. Damage is caused in three ways: sucking plant sap when feeding, excretion of honeydew leading to sooty mould and some species can transmit plant viruses leading to distortion and disfigured plant growth. Biological control with parasites, predators and fungal pathogens are available depending on crop and environmental conditions. There are a large number of aphid species and identification can be important when parasitic wasps are to be used. Depending on the species there can be alternate plant hosts. Winged forms develop under conditions of high density to migrate to alternate hosts. Resistance to some insecticides is a serious issue with some species. |
| Control | Adult parasitic wasps emerge from the mummies and females lay their eggs into aphids. The next generation of parasitic wasps develop inside the aphid, which converts into a leathery mummy. The adult parasitic wasp emerges through a hole at the rear of the mummy. The first mummies are noticed in the crop around 10-14 days after the first introduction. Visual effect: Parasitized aphids turn into a brown mummy. Most effective between 20 and 25°C. Effectivity is reduced at temperatures above 30°C. |
