Abstract

Paddy stem-borer (Tryporyza Incertulas Walker) infestation is very much influenced by meteorological factors. The effect of various weather elements on its incidence is endeavoured in present statistical analysis. It is found that less moisture content in the atmosphere in the elongation stage and a minimum temperature lower than 23 deg. C and sunshine hours more than 8 hours in flowering stage are favourable for increased larval activity in the earing stage of summer paddy crop at Bhubaneshwar. Northeast region of India are prone to heavy attack in summer and winter crops earing stage. Similar studies for other stations are necessary to draw general conclusion about threshold values of meteorological parameters to be used in forewarning of the infestation of stem-borer in paddy.
