Abstract

Investigations were carried out on the true identity of the thelytokous species purported to be Trichogramma brasiliensis (Ashmead) (= T. brasiliense), which is used in India in biological control programmes, as the holotype of Ashmead's species is placed under the genus Trichagratnmatoidea Girault at present. Morphological and molecular studies in combination with crossing experiments conclusively proved that this species was con specific with T. pretiosum Riley. Thelytoky in T. brasiliensis auctt. used in India is found to be Wolbachia - induced and reversible by administering antibiotics.
