If you have a pond or pool in your garden, place stones to jut up above the surface of the water so adult wasps may land and drink without drowning. It can parasitize many species of leaf miner. Diglyphus isaea - Leafminer Parasites are tiny beneficial insects that kill leafminer larva in the mine and lay an egg in it. The adult parasite exits the tunnel sometime later and will then go on to lay 200 300 eggs during its nearly month-long life. The first change noticeable in the pupa is the red compound eyes. Sales and Customer Service: Release at a rate of 0.25 to 0.5 per 10 square feet. Keep out of direct sunlight. 1991.

Index of Entomophagous Insects. The females are slightly bigger than males and like other species; these wasps also grow through four developmental stages such as eggs . Diglyphus isaea (Walker) and Neochrysocharis formosa (Westwood) (Hymenoptera: Eulophidae) are common idiobiont parasitoids of leafminers attacking vegetable crops. Egg: The adult female Diglyphus parasitoid stings the dipteran host larva to paralyze it. While destructive leaf miners often survive pesticide treatments because they are protected inside the tunnels, they cannot escape the parasite, which raps its antennae on the mine to locate the miner. But first a female Diglyphus punctures a leafminer larva to paralyze it. Diglyphus isaea Diglyphus isaea is a black parasitic wasp of 2 to 3 mm long that occurs naturally in Europe, North-America and Asia.

In countries that have severe pest problems with leafminer flies in greenhouse crops, the parasitoid, Diglyphus isaea, is one of several species that are mass produced for release into greenhouses to control the flies. HOW TO RELEASE: Make introductions when leaf miner infection increases. Adult females will also feed on host larvae as a source of protein in order to produce more eggs (usually the smaller host larvae that are not large enough to support its eggs). Regulate release of wasps by gently tapping and tipping the vial while walking through the crop. The results showed that D. isaea was a strongly synovigenic parasitoid, of which OI value was 0.002.
