Leafhopper population showed highly significant positive association with Bright Sunshine Hour (BSS) (r = 0.72**) and maximum temperature (MaxT) (0.70**) during kharif, 2014. The highest activity of mite was recorded during 3rd week of October and 2nd week of September during kharif 2014 and kharif 2015, respectively. Fruit damage caused by Helicoverpa armigera (Hubner) Hardwick showed highly significant negative association with WS (r = -0.73**), MinT (-0.78**) and RH2 (-0.83**) whereas, BSS (0.77**) and MaxT (0.74**) revealed highly significant positive association during kharif, 2014. During kharif, 2015; MinT (-0.70*) exerted significant negative association. Earias vittella (Fabricius) study revealed that BSS (r = 0.88**) and MaxT (0.86**) exhibited highly significant positive impact whereas, WS (-0.75**) and RH2 (-0.90**) had highly significant negative association during kharif, 2014. There was highly significant positive association (0.99**) in simultaneous occurrence between Scymnus sp. and mite, whereas it was highly significant between spiders and aphid during kharif, 2014. As in case of kharif, 2015; coccinellids significant positively associated with aphid (0.88**).
