Diversity of Arthropods in Relation to Insecticide and Biopesticide Treatments in Okra

Present study was carried out during 2019 at the Vegetable Research Farm, Punjab Agricultural University, Ludhiana to generate information on diversity of invertebrates in okra. Study revealed that okra crop harboured by 27 invertebrate species belonging 11 orders and 26 families. Of these, maximum belonged order Hemiptera followed Coleoptera. Higher values Shannon-Wiener index (1.75, 1.84) Simpson’s (0.26, 0.17), respectively were recorded for both phytophagous arthropods predators untreated control plots. This is neem/ other insecticides treated Imidacloprid lowered arthropod population. Occurrence a significant positive correlation with temperature (r=+0.37 +0.99) relative humidity (r=+0.04 +0.80) except few hemipterans coleopterans.
