Tortricid moth fauna diversity (Lepidoptera: Tortricidae) in Kargil district, Ladakh, India

Abstract

Tortricid moths were collected from different parts of Kargil during 2010-2012 to determine their diversity, evenness, dominance and species richness. The whole collection of 210 tortricid moth specimens comprised of 18 species were captured from diverse localities of Kargil by using light trap operated from dusk to dawn, out of which one specie (Acleris birdi sp. nov.) was reported as new to science and two species [(Crocidosema plebejana Zeller and Matsumuraeses phaseoli (Matsumura)] as new to Ladakh. When monthly data of individual count is taken into consideration, highest numbers of specimens (94) were captured in the month of August followed by July (76) while as minimum (8) were collected in the month of May and September each during entire study period. Further Diversity index (H), Evenness index (J), Index of dominance (D) and Species richness (M) were observed as 1.11627, 0.755707, 0.244293 and 7.320583 respectively.
