Abstract
The present investigation was carried out at Biological control laboratory of G.B. Pant Univ. of Agri. & Tech, Pantnagar, Distt.Udham Singh Nagar (Uttarakhand) to study the biosystematics of some Eulophid parasitoids (Hymenoptera : Eulophidae) from Northern India. As we know that India is blessed with a rich beneficial insect fauna. It is one among 12 “mega diversity” countries and accounts 6.2% of Hymenoptera fauna which has a large percentage of parasitoids of crop pests. Considering the biosystematics in Agricultural Entomology there is an ample scope for its exploitation in biological control. Among the insects, the members of family Eulophidae is ecologically and economically most important parasitoids for controlling crop pests. The present study contain a detailed account of family Eulophidae and in family Eulophidae an attempt has been made to give a detailed account of 13 genera, amongst which one genus Bishtiella is new to Entomological Science. A contribution of 24 new species viz., Tetrastichus figensis, T. clubensis, T. minutus, T. eggaevorus, T. narendranii, T. mallitalensis, T. hillensis, T. bhimtali, Aprostocetus hayatae, A.silvestriae, Neotrichoporoides mani, Mestocharella kausaniensis, M. pauri, Tamarixia brassicae, T. minerensis, Bishtiella indica, Elachertus indica, Euplectrus scutellaris, Entedon erdosensis, E. dubeyensis, Chrysocharis malus, C. orientalis, Neochrysocharis parthenicus and Euderus elongata are new to entomological science. Seven species namely Tetrastichus clavatus Khan et al., T. taprobanensis Ranweera, Euplectrus bristlis Khan et al., Diglyphus horticola Khan, Chrysocharis longiclavatus Khan et al., Euderus albitarsis (Zett.) and E. agromyzae Gangrade have been redescribed. A key to serve as a ready reckoner for quick identification of Indian Eulophid genera has been prepared. A checklist for all the examined genera indicating latest acceptable names has also been compiled.
