Abstract: The present investigation entitled “biology of rice moth on different host” was carried out under laboratory condition, Department of Entomology, Rajasthan College of Agriculture, MPUAT, Udaipur during august, 2017. The experiment was conducted to assess the effect of five host viz., maize, rice, pearl millet, wheat and sorghum on the biology of C. cephalonica. The result revealed that the minimum larval period (32.40 days) was recorded on sorghum and maximum was on wheat (43.15 days). The maximum larval weight was recorded on sorghum (52.55 mg) and minimum on wheat (42.00 mg). The minimum pupal period was recorded on sorghum (9.45 days) and maximum on wheat (10.20 days); while maximum pupal weight was recorded on sorghum (38.50 mg) and minimum on wheat and maize (33.95 mg). The minimum hatching period (4.00 days) was observed on sorghum and maximum on wheat (5.50 days). The maximum adult emergence was recorded on sorghum (80.00%) and minimum on wheat (68.75%). The Growth Rate Index was maximum on sorghum (1.73) and minimum on wheat (1.18). The highest mean fecundity of female (301.75 eggs/female) was recorded on sorghum and minimum was on wheat (230.75 eggs/female). The maximum adult longevity period (10.50 days) was recorded on sorghum and minimum on wheat (8.25 days). The minimum developmental period was recorded on sorghum (46.20 days) and maximum was on wheat (57.80days).
