abstract
The activity of termite in Bt cotton commenced from 2^nd week of August [32^nd standard meteorological week (SMW)] and continued till 4^th week of December (51^st SMW). During 2^nd to 4^th week of August (32^nd to 34^th SMW), the termite activity was found negligible (2.8 to 7.2 termites/stick) in the field, when crop age was four weeks. The termite activity was found 12.6 to 28/stick during September (35^th to 39^th SMW). The population continuously increased every week. It was between 28.6 and 50.2 per stick in October (40^th to 43^rd SMW). The peak incidence was noticed during the end of November (47^th SMW). The pest activity was found higher in cotton field during first week of October (40^th SMW) to the last week of November (47^th SMW). The activity of this pest was started to reduce from 1^st week of December. The evaporation and soil temperature (afternoon) at 10 cm depth was highly significant and positively correlated with termite incidence, whereas morning relative humidity had highly significant negative association with population. The wind speed, maximum and minimum temperature, soil temperature at 5 cm, 10 cm and 15 cm depth at morning hours and soil temperature at 5 cm and 15 cm depth during afternoon hours had significantly positive relationship with termite incidence in cotton.
