abstract
Field studies were taken up to evaluate the efficacy of various intercrops in wheat for the management of Odontotermes obesus Rambur during November 2013 to March 2014 and November 2014 to March 2015 at Research Farm, Institute of Pesticide Formulation Technology, Gurgaon, Haryana. The termite population was recorded at fifteen days interval and at 15 DAS (Days after Sowing) the termite population ranged from 35.33 – 66.67 and 31.33- 61.67 in intercropped plots during first season and second season, respectively. On 135 DAS, the population density of termites were the least in safflower, mustard, gram and pea intercropped plots which recorded 41.33, 41.67, 42.00 and 43.00 numbers, respectively and were also on par with each other. The trend continued to be the same during second season and mustard intercropped plots recorded 28.33 numbers at 105 DAS, which was on par with the plots intercropped with safflower (28.33), gram (29.33) and pea (30.67). The order of intercrops influencing the reduction in termite population for both the season was safflower > mustard > pea > gram > fenugreek > coriander > ajowain > linseed.
