Red Scale Parasite (Aphytis melinus) California red scale is the favorite prey of these parasitic wasps, although citrus red scale, oleander scale, San Jose scale, ivy scale, and citrus yellow scale are other prey. Aphytis are shipped as adults, and the adult females lay their eggs in red scale. The larvae consume their host, and each A. melinus kills more than 30 scale insects.

Delphastus catalinae is considered an effective biological control agent for whiteflies because of its high prey consumption rates, long adult survival, and high reproduction rates. Delphastus catalinae has received research attention in Florida and other states for its value as a predator of the whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), which is an economically important pest of ornamental and agricultural crops.

Three species of predatory fly parasites mixed in your order: Spalangia cameroni, Muscidifurax zaraptor and Muscidifurax raptorellus.
Fly parasites are an effective natural enemy of flies. Frequent releases of fly parasites can drastically reduce common housefly and stable fly populations. Fly parasites search fly-breeding areas for fly pupae containing developing flies. Once a fly parasite finds a pupa, it drills a hole through the casing and inserts several eggs through the hole.
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.
