Шаблон:Short description Шаблон:Taxobox
Aphidoletes aphidimyza, commonly referred to as the aphid midge, is a midge whose larvae feed on over 70 aphid species, including the green peach aphid.
Description
The adults are small (less than Шаблон:Convert long), black, delicate flies (similar to a fungus gnat) that live for an average of 10 days, feeding on aphid honeydew. They hide beneath the leaves during the day, and are active at night.
Life cycle
Females deposit 100-250 tiny (Шаблон:Convert) shiny orange eggs singly or in small groups among aphid colonies that hatch in 2–3 days. After 3–7 days the larvae drop to the ground and burrow Шаблон:Convert inches into the soil to pupate. They are most effective at Шаблон:Convert and high relative humidity.
Behavior
The small, bright orange, slug-like larvae inject a toxin into aphids' leg joints to paralyze them and then suck out the aphid body contents through a hole bitten in the thorax. Larvae can consume aphids much larger than themselves and may kill many more aphids than they eat when aphid populations are high. A single larva grows up to Шаблон:Convert long and kills 4-65 aphids per day.
Use in biological pest control
The aphid midge is commercially grown by insectaries for use as biological pest control in commercial greenhouse crops. It is supplied as pupae in trays or bottles containing a moist substrate such as vermiculite or peat moss for the pupae to complete their development. Once they are placed in the greenhouse they usually emerge from the shipping container as adults to begin egg-laying in 3–7 days depending on temperature.
