none Enter Field experiment was conducted during rabi season of 2012-13 at the Agricultural Research Station, Gulbarga, University of Agricultural Sciences, Raichur, Karnataka, India, to know the impact of different intercrops on activity of natural enemies of Helicoverpa armigera (Hubner) in chickpea Cicer arietinum. Impact of six different intercrops on activity of Campoletis chlorideae and tachnid fly parasitoid in chickpea intercropping system revealed that chickpea intercropped with coriander (4:2) recorded significantly highest total of 24.44 and 8.89 per cent parasitization by C. chlorideae and tachnid fly respectively from the H. armizera larvae colleted at 40 days aged chickpea crop and reared in laboratory. The similar trend of highest of 22.22 and 4.44 per cent parasitization was found in larvae collected from the field of 60 days aged chickpea crop. Similarly significantly highest number of coccinellid population were recorded on chickpea + safflower (4:1) intercropping sequence (0:00 to 2.00 coccinellid per ten plants both on main crop and intercrops). noneEmail20150307 (chandru.maalur@gmail.com)
