Aphidoletes aphidimyza; gallmidge against aphids
Adult APHIDEND gallmidges are rather fragile insects of about 2.5 mm long with long, thin legs. The female has a wing length of 2.5-3.5 mm. Male antennae are long and hairy; female antennae are shorter. Eggs are small and shiny orange red, but hard to spot. The larvae are 0.3-3 mm, long and orange in color. The larvae pupate in the ground. An aphid that is killed by a gallmidge larva stays attached to the leaf for a while, being sucked and not looking like an aphid anymore; later it turns brown or black and will fall off the leave.
Mode of Action:
The larvae of the gallmidge injects a poison into the aphid, which causes the aphid to paralyze and easy to suck by the larva. If many aphids are present, the gallmidge larva kills more aphids than he can eat. Adult gallmidges do not prey on aphids, but only lay eggs near the aphid colony. They are active at night. Honeydew, produced by the aphids, promotes oviposition of the gallmidge.
For the control of many species of aphids in greenhouses and iindoor plantings. Keep in mind repeated introductions. The product is sensitive to various chemical plant protection products. Ask advice for introduction strategy.
