Sujatha S, Sunitha ND, Vastrad AS and Patil MB

We undertook comparative analysis of natural enemies in grape ecosystem in Vijayapur District of Karnataka during rabi season of 2016-17(October-April). Studies included three locations namely Vijayapur (Study area-1), Aliyabad (Study area-2) and Tikota (Study area-3) where in common agronomic practices were maintained but different plant protection measures for major insect pests. Natural enemies were collected through different methods Viz., Herbivore induced plant volatile (HIPV), Yellow sticky trap (YST) and Sweep net (SN). A total of 563.33, 1035.55 and 1466.80 natural enemies were collected from study area-1, 2 and 3 respectively. Relative abundance of natural enemies at three locations was also calculated, the highest abundance was recorded for coccinellids and lowest abundance for ichneumonids. The Simpson index values were 0.76, 0.79 and 0.81, Shannon index 1.68, 1.70 and 1.73 and Evenness were 0.96, 0.93 and 0.87 for study area-1, 2 and 3 respectively. Our results showed that higher diversity was found in Tikota.
