The larvae of some Lepidopteran (moths), Coleopteran (beetles), Hymenopteran (sawflies) and Dipteran (flies) insects generally feed within a leaves by producing large blotches or meandering tunnels that are called mines. Because of this mining and feeding behavior of these insects are called leafminers. These leafminers can cause a significant health and aesthetic damage to many plant species.
Although there are several kinds of natural enemies that can keep the populations of leafminers under control, it has been proved that the release of the warm weather wasp parasitoids, Diglyphus isaea as biological control agent have a potential to control different species of leafminers that cause a serious damage to many crops including beans, celery, cucumbers, eggplants, lettuce, onions, pepper, potatoes squashes, tomatoes and watermelons whether they are grown in the greenhouses, fields, orchards or gardens.
Parasitic Diglyphus isaea are called mini wasps because they are very small about 1.5-3 mm long. These mini wasps are black in color with a yellow stripe on their hind legs and possess short segmented antennae. The females are slightly bigger than males and like other species; these wasps also grow through four developmental stages such as eggs, larvae, pupae and adults. Wasp larvae start feeding on the leafminer larvae immediately after hatching from eggs and develop thorough 3 larval stages (instars). Eventually the mature wasp larva pupates in the mines on the upper surface of the leaf. After 6-9 days of pupation, adult wasp emerges from pupa and lifecycle continues. Under optimal conditions i.e. temperatures between 75-90°F and about 80% relative humidity, egg to egg life cycle of mini wasp Diglyphus isaea is completed within 2 weeks.
