Against fly wasp Diglyphus

larva

Diglyphus isaea The parasitic wasp Diglyphus isaea is an efficient biological control agent of leafminers used in several greenhouse vegetables (e.g. tomato) and ornamentals (e.g. gerbera). Diglyphus isaea parasitizes the tomato leafminer, as well as the serpentine leafminer and the pea leafminer. It is an ecto-parasitoid, meaning that an egg is deposited next to its host larvae. But first a female Diglyphus punctures a leafminer larva to paralyze it. Female Diglyphus also host feed on young leafminer larvae. The most important benefit is the fast population build-up, enabling Diglyphus to control an increasing leafminer population in a short time span.
