Insect pests are the important production constraints in grape cultivation next to diseases. Survey of Scirtohrips dorsalis Hood at progressive former field for grape, Bijapur during 2013-14 at weekly, revealed that thrips population was observed immediately after both April and October pruning. Highest population of 14.60 thrips/shoot was observed during third week of May after April pruning, which coincided with inflorescence period. Similarly thrips population was observed with highest of 16.25 thrips/inflorescence during first week of December after October pruning. Correlation studies with weather parameters and insect incidence revealed that evening relative humidity was significantly negative correlation with population of thrips (-0.58*) and signifact positive correlation with population of thrips (0.66*) after April pruning. Thrips population was negatively correlated with minimum temperature (-0.35), wind speed (-0.39) and rainfall nil after October pruning.
