Studies on sex ratio of castor shoot and capsule borer, Conogethes punctiferalis Guenee (Lepidopteara: Crambidae) in Castor

S Sambathkumar, C Durairaj, S Mohankumar and N Ganapathy

The castor shoot and capsule borer, Conogethes punctiferalis (Guenee) is an important and one of the most devastating pests of castor. The sex ratio of C. punctiferalis adults was compared for two years (2011 and 2012) on castor. The sex ratio (♂: ♀) was female- biased during both years and it was 1.0:1.92 and 1.0:1.41 respectively. The chi-square test for heterogeneity in sex ratio, showed non-significant departure from 1.0: 1.0 ratio in both years. The paired ‘t’ test also revealed the non-significant difference in the sex factor between two years
