Aphidius colemani and Aphidius ervi are both parasitic wasps of a wide range aphid species. Using a mix of the two has a far greater probability of success in a greenhouse situation. Aphid endoparasitic wasps including Aphidius colemani and Aphidius ervi are 2-3 mm and 4-5 mm long and slender bodied, respectively. These two endoparasitic aphid wasps are mixed in a single package to target their different aphid species.

one package of HB 50 mil. nematodes
one package of SC 50 mil. nematodes
Steinernema carpocapsae and Heterorhabditis bacteriophora an evolved insect-killing nematodes that kills its hosts within a few days of infection. The Steinernema carpocapsae and Heterorhabditis is considered a generalist parasite and has been effectively used to control a variety of pest insects.
Mix the two together and cover up to one acre. $78.50

Predator of two-spotted spider mite, European red mites, broad mites, cyclamen mites, and russet mites. Amblyseius andersoni is is a predatory mite that feeds on many types of mites. It is ideal for preventive protection of greenhouse or outdoor ornamentals, vegetables and fruit crops.

Amblyseius swirskii is a very effective generalist predatory mite used to suppress immature thrips, two-spotted spider mites, cyclamen mites, broad mites, and whiteflies in ornamental, fruit and garden crops.

The wasp genus Aphidius is a large group containing numerous species, all of which attack aphids and provide natural control of aphids in backyard gardens, commercial fields, and urban landscapes. They are generally used in greenhouses.
Aphidius colemani are small braconid wasps. Females lay eggs singly in aphid nymphs. The wasp larvae consume the aphids from inside. As the larvae mature and the aphids are killed, the aphids turn into mummies. After the larvae pupate, each adult wasp emerges through an exit hole cut in the mummy. In addition to killing aphids directly, mechanical disturbance of aphid colonies by the searching behavior of the adult wasps causes many aphids to fall off the plants and die.

Aphidius ervi attack many species of larger aphids such as the green peach aphid and brassica aphids.

A relatively large wasp (twice the size of Aphidius colemani) with a black, slender body with brown legs and long antennae. The female wasp injects an egg in the aphid with her ovipositor. Hatched larvae eat the aphid from the inside leading to the formation of a a golden-yellowish-brown mummy. Finally, a new adult parasitic wasp leaves the mummy through a round hole.
