Abstract :

 Field trials were conducted at Mahatma Phule Krishi Vidyapeeth, Rahuri for fourteen years from 1996–

2010 to evaluate influence of weather parameters on the incidence of sorghum shootfly (Atherigona soccata, Rondani) in kharif and rabi seasons. It was concluded that peak incidence (dead hearts) of shoot fly in kharif 
season was in the month of August while in rabi season it was in the month of October – November. Minimum temperature, RH morning and evening showed significant and positive effect while maximum temperature had significant 
and negative effect on the incidence of shoot fly. The regression equation for weather parameters three weeks prior to 
observations showed that there was significant and positive effect of minimum temperature, RH morning on the incidence of shoot fly. It may be predicted that one unit increase in minimum temperature and morning humidity would 
increase the incidence of shoot fly from 0.60 to 28% and 0.8 to 7%, respectively. The regression equation of the data 
of weather parameters recorded three weeks prior to observation is useful for early prediction of shoot fly for adopting 
control measures.
