Abstract

Three species of Trichogramma, T. rabindrai, T. pieridis and T. giriensis have been described as new. The first species was reared from the eggs of a sphingid on a marshy weed bordering paddy fields at Someshwar and Saligrama in Udupi District, the second one from those of a pierid on Cassia fistula at Balehonnur, Chickamagalur District (both Karnataka) and the third from unidentified lepidopterous eggs on bamboo leaves at Tusharagiri (Kerala). The taxonomic significance of scutellar bristles, RS1 row of setae in the forewings and setal arrangement in the hind wings are discussed. A key to differentiate the three newly described species from other closely resembling ones has been included.

Abstract

Two new species of Trichogrammatoidea, Trichogrammatoidea ruficolorata and T. brevicaudata are described from Bangalore, India. The males are morphologically similar to T. armigera and T. fulva, respectively. The relative lengths of ovipositor to hind tibia are markedly different in both pairs of species serving to differentiate between these species pairs. Females have therefore been designated as holotypes.

Keywords

Trichogrammatoidea ruficolorata, Trichogrammatoidea brevicaudata, Cryptic Species.

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.
