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). Keywords: Biology, rice moth, C. cephalonica, host 1. Introduction The rice moth, Corcyra cephalonica Stainton (Family: Pyralidae, Order: Lepidoptera) is one of the most destructive pests of stored cereals in Asia, Africa, North America and Europe causing severe economic losses (Atwal and Dhaliwal, 2008) [1] . It attacks rice, wheat, corn, sorghum, groundnut, cotton seeds, coffee, spices and cocoa beans under storage conditions. The adults are nocturnal and each female lays about 90-300 eggs with an incubation period of 5 days, 23-25 days of larval period, 10 days of pupal period and adult life span of 1 week (Fenemone and Prakash, 2009) [3] . The larvae cause damage to broken grains by forming silken webs and feeding inside them. Hence the present investigations entitled “Biology of rice moth (C. cephalonica, Stainton) on different host. 2. Materials and Method 2.1 Experimental details The present experiment was conducted on the biology of rice moth on different host was conducted in the Department of Entomology, Rajasthan College of Agriculture, Udaipur during 2017, under laboratory conditions with 31.3 0 C temperature and 72-74% humidity. The detailed methodology used for the investigation is described as under: 2.2 Maintenance of nucleus culture The nucleus culture of the rice moth was maintained by collecting adult moths from the infested sorghum seeds at Biocontol laboratory, Department of Entomology, RCA Udaipur. For carrying out the experiment, adults of rice moth were reared in laboratory in glass jars of 5 kg capacity, containing both broken as well as unbroken rice grains. The filled in jars were covered with muslin cloth and introduced into oven for sterilization at 100 0 C for about 1 hour, in order to kill eggs and other hibernating macro as well as some microorganisms. The oven exposed broken rice was then introduced @ 3 kg in each of the glass jars. A cotton plug soaked in 5 per cent sucrose solution was provided in the jars for feeding the adults moths to increase the fecundity of moth (Pareek and Kushwaha 1971) [4] . Each jar was then scattered with 5 gram yeast extract and 0.5 gm streptomycin sulphate. Most of the eggs were laid between the double layer of muslin cloth from where these were collected daily with the help
