Seasonal Incidences of Stem Fly on Soybean in Relation to Weather Parameters

Insect damages the soybean crop right from germination to till harvesting stage. Stem fly Melanagromyza sojae (Zehntner) causes 30 to 50 per cent reduction in grain yield .Number of infested plants due to M. sojae was recorded on soybean between 27th to 38th MW (12.70 to 27.2 per cent) and 30th to 40th MW from (10.90 to 25.70 per cent) during 2010- 2011 and 2011-2012, respectively. Simple correlation and regression studies revealed that there was significant effect of different weather parameters on incidence of stem fly of soybean.
