    Not AvailableSurveys were undertaken to document the fauna of insects, spiders and entomopathogenic nematodesacross India despite the travel restrictions due to COVID-19. The expeditions undertaken yielded several species of natural enemies viz.,Chalcididae (66.32%), Eulophidae (19.94%), Pteromalidae (4.14%) and Encyrtidae (3.37%) of Hymenoptera and 14 species of trichogrammatids representing 7 genera. The predominant genera of hymenopteran insect parasitoids were identified as Dirhinus Dalman (30.47%) followed by Brachymeria Westwood (27.73%), Hockeria Walker (22.27%) and Antrocephalus Kirby (18.75%). Revisionary studies of the braconid parasitoid, Apanteles sp. ater-group including subgroup eublemmae of the genus (Hymenoptera: Braconidae) of the Oriental region was carried out with an illustrated key, in which a total of 97 species were recorded and illustrated. Three species of tachinid flies, Peribaea orbata on larva of Spodoptera litura, Halidaia luteicornis on larva of Parnara sp., Sturmiopsis inferens on larva of Sesamia inferens and Carcelia sp. from the larvae of Helicoverpa armigera (Noctuidae) were identified and described. The spider fauna of rice ecosystem was documented, where six species of long jawed orb weaver, Tetragnatha species have been described of which T. keyserlingi was the predominant species across the surveyed locations in Tamil Nadu. The species, Tetragnathanitens collected from Tamil Nadu and Telangana was the first report from India. The spitting spider, Scytodes fusca Walckenaer of family Scyotidae was redescribed with documentation of variations in the vulval pattern of the female and theory about the introduction of this Pantropical species to India.Not Availabl
