Influence of magnetic field and diet on growth and development of Corcyra cephalonica

The present experiment was carried out in the laboratory of Entomology, Dr. PDKV Akola, during August 2017-18 and 2018-19, to find out the Influence of magnetic field and diet on growth and development of Corcyra cephalonica. The nine main treatments were the exposure of Corcyra larvae to the magnetic field for 0 hrs, 24 hrs, 12 hrs, 6 hrs, 3 hrs, 2 hrs, 1½ hrs, 1 hrs and ½ hrs duration and four sub treatments were rearing of the larvae on diet CSH-35 (D1), Maldandi 35-1 (D2), Swati (D3) and CSH-9 (D4) variety of sorghum. Observations were recorded based on pooled data, after 8 days on weight, length and larval mortality of Corcyra. The result indicates that, rearing of Corcyra in the magnetic field for 12 hrs recorded maximum weight 1.36 mg in M12 and maximum length 5.08 mm in treatment M12 and maximum mortality of Corcyra larvae was observed in 24 hrs magnetic field treatment.
