Abstract: The current studies were carried out in temperate conditions of Kashmir valley during 2013-2015. The patches of fruit crop selected were located in different types of landscape categories. Highest species richness of 46 was observed in landscapes of Budgam, belonging to 5 orders, 31 families and 20 genera of class Insecta. Of all these insects, genus Lasioglossum was most abundant flower visitor followed by comparatively less abundant genera Xylocopa spp. Andrena spp. Megachile spp. Syrphus spp. and Musca spp. The minimum value of Simpson diversity index, Shannon diversity indices and Simpson’s dominance were 5.415, -6.056 and 0.8115, respectively in district Srinager. The species richness of pollinators varies from minimum of 32 (Srinager) to maximum of 46 (Budgam). The equitability of species varies from minimum of 0.718 in Srinager to maximum of 0.931 on in Pulwama. The Pielou’s evenness, Nakamaru’s richness, Menhinick’s and Margalef’s varies across the different landscapes. Species richness showed a corresponding and parallel increase with various indices estimated. The unequal distribution of abundance between species on three fruit crops allow the use of dominance index of Berger-parker to express the proportion of individuals accounted for by the most abundant species (Lasioglossum marginatum) in each site of investigation and it varies from minimum of 0.087 in Pulwama to maximum of 0.121 in Srinager. The family Halictidae were most abundant. The dissimilarity coefficient of species richness varies from 11.00 to 19.83. The order Hymenoptera was most abundant with rank (K) one and K-dominance of 0.602 followed by Diptera with rank value 2 and K-dominance value -1.259 and so on.
