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.
Stethorus punctum is one of the most important and frequent predators of spider mites in fruit orchards. Beetles consume all stages of mites; adults can consume 75 to 100 mites per day and large larvae can devour up to 75 mites per day, so they quickly lessen an outbreak of spider mites. Adults are very active when in fruit trees and if disturbed they will often fall to the ground. They are good fliers, and therefore tend to concentrate in areas of the orchard where mites are plentiful and disappear when the mite population becomes low. There must be 2-5 motile mites per leaf to keep S. punctum in an orchard, and pockets of 8-10 mites per leaf are required for reproduction. Photo credit: Gilles San Martin
Please check back for ladybugs on September 28th.
Ladybugs, or lady beetles (Hippodamia convergens) are the best-known garden predators available. Ladybugs will eat aphids, mites and other soft- bodied insects.
The Green lacewing larvae is the most beneficial stage with the lacewings. They feed on soft-bodied insects like aphids, but will also feed on caterpillars and some beetles. The biggest benefit of lacewing larvae is how aggressive they are. They will eat anything they can catch, and they are always hungry. They’re also cost effective, especially the eggs. They have the ability to quickly knock down moderate levels of aphid infestations, as well as help control many other pests.
Green Lacewing eggs are oval and pale green. Just before the larvae hatch, eggs turn gray. The eggs are shipped in vials with food and a carrier such as rice hulls, bran or vermiculite.
There are 3 species of predatory fly parasites mixed in your order: Spalangia cameroni, Muscidifurax zaraptor and Muscidifurax raptorellus.
Fly parasites search fly-breeding areas for fly pupae containing developing flies. Once inside, the eggs hatch inside the fly pupa and feed on the developing fly and after two to three weeks of feeding, an adult fly parasite emerges to repeat the cycle. Each female fly parasite can kill approximately 100 immature flies in her lifetime.
