Morphometrics of Trichogramma spp. collected from Haryana and Punjab

The genus Trichogramma constitutes an important group of egg parasitoids. It has wide range of host insects, covering many pests of agricultural crops as well as some key insect pests of important forest trees. Amongst the biological control agents, species of Trichogramma are the most common. The present study, with the Trichogramma species collected during the four years’ survey (2012–2015), across different districts of Haryana and Punjab, has led to study of nine species: T. achaeae, T. agriae, T. breviciliata, T. chilonis, T. chilotraeae, T. flandersi, T. japonicum, T. plasseyensis and T. poliae. Descriptions are given for these along with their detailed diagnostic characters, and additional morphometrics. Host range and distribution from Haryana and Punjab are also discussed.
