Field experiments on population dynamics of termites incidence in groundnut were carried out under field conditions during summer and kharif
, 2012 at Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand. The activity of termites commenced from 1st week of March [10th Standard meteriological week (SMW)] and continued till 2nd week of June (14th SMW) during summer, whereas 4th week of July (30th SMW) to 1st week of November (43rd SMW) during kharif
. The pest activity was found higher in groundnut field during 2nd week of March (11nd SMW) to 2nd week of June (23th SMW) in summer, whereas it was 3rd week of September (37nd SMW) to the end of the crop period during kharif
. The pest activity was at peak level on 2nd week of June (23rd SMW) and 2nd week of October (40th SMW) during summer and kharif
The evaporation, minimum, maximum and mean temperature, soil temperature at 5 cm, 10 cm, and 15 cm depth at afternoon hours and soil temperature at 15 cm depth at morning hours had highly significant positive relationship with termites activity in groundnut in both the seasons. Morning, evening and mean vapour pressure had highly significant negative relationship and wind speed had significant negative association with termites population in groundnut in both the seasons. Morning, evening and mean relative humidity had negative relationship with termites population but non-significant in summer and significant in kharif season.
