dc.description.abstractThe seasonal biology of shoot fly (Atherigona soccata Rondani) was studied on two maize varieties; susceptible Basi local and resistant HM-4 during spring season 2009. Minimum oviposition and dead heart were observed in resistant variety HM-4. The larval and pupal period were observed maximum on resistant variety HM-4 than susceptible on Basi local. Adult emergence was observed 48.03 and 73.06 per cent on resistant variety HM-4 and susceptible variety Basi local, respectively. The fecundity and oviposition period were observed maximum on susceptible variety Basi local and minimum on resistant variety HM-4. The adult longevity was observed maximum (8.30 days) on susceptible variety Basi local and minimum (6.09 days) on resistant variety HM-4. The larval growth index and total growth index were maximum on susceptible variety Basi local and minimum on resistant variety HM-4. Among different morphological plant factors plant height, number of leaves per plant and leaf length were negatively correlated. Similarly, the biochemical constituent phenols and tannin were negatively correlated whereas protein, sugar and chlorophyll in plant leaves were positively correlated with shoot fly growth and development parameters. The oviposition and dead hearts were recorded minimum in plots treated with imidacloprid 17.8 SL as seed treatment followed by spray of carbaryl 50 WP and endosulfan 35 EC. Similarly, maximum yield was recorded in imidacloprid 17.8 SL as seed treatment followed by spray of carbaryl 50 WP and endosulfan 35 EC.en_US
