Description:
A parasitic wasp that attacks many species of Leafminer pests. The Adult wasps are metallic green and black, 2 - 3 mm in length. Females are larger than males. Sex ratio is 50/50. Diglyphus females will track down and sting leafminer larvae in the 2nd an 3rd instar laying an egg inside the mine. The eggs will hatch and the larvae will feed on the leafminer and then pupate in the leaf mine. Diglyphus larvae are very difficult to locate. However, inspecting leaves by putting a light behind the leaf can easily identify the black and green pupae. Diglyphus will kill a large number of leafminer's for host feeding. The leafminer pest have only 3 instar's of development and develop quickly, in greenhouse conditions. Depending on the conditions, there may be only 1 day between instar developments.
