Trichogrammatidae

Ovipositing Trichogrammatoidea bactrae, copyright ICAR-National Bureau of Agricultural Insect Resources.

Belongs within: Chalcidoidea.
Contains: Trichogramma, Oligosita.

The Trichogrammatidae are a group of minute chalcidoid egg parasites characterised by the possession of three-segmented leg tarsi. Members are divided between the Trichogrammatinae, in which the aedeagus has accessory structures such as a phallobase, parameres and volsellar digiti, and Oligositinae, in which the aedeagus is simple and tubular (Naumann 1991).

Characters (from Naumann 1991): Length 0.15–1 mm; not strongly sclerotised, mostly smooth; non-metallic, often pale coloured; genae not posteriorly carinate; antennae shorter than head and thorax, 4—9-segmented, often with a very short funicle and large club; pronotum not conspicuous in dorsal view; mesosoma dorsally sparsely setose; notauli distinct; axillae advanced; mesopleuron not enlarged; fore wing often with long marginal cilia and often with setae of disc arranged in radiating lines; postmarginal vein absent; stigmal vein often short or absent; legs slender; tarsi 3-segmented; fore tibial spur short and straight; fore basitarsus without a strigil comb; cerci not advanced; ovipositor rarely exserted.

Belongs within: Trichogrammatidae.

Trichogramma is a genus of minute egg parasitoid wasps. Species of this genus are among the most widely used wasps in the biological control of Lepidoptera species.

Characters (from Girault 1918): Female antenna six-segmented; funicle two-segmented, shorter than pedicel; clava solid, without terminal nipple. Male antenna four-segmented, with long and nodular single-segmented clava, clothed with long hairs. Forewings with discal cilia all in straight lines; marginal vein short, more or less equal to stigmal and slightly curved; stigmal vein long with a slender neck; distal venation more or less bowed. Abdomen more or less pointed.
