ABSTRACT
Life-fertility table for the legume pod-borer, Maruca vitrata Fab. on cowpea was studied under laboratory conditions. The maximum daily mean progeny production per female was 116.16 on the 29th day of pivotal age. Estimate innate capacity for increase (re) and finite rate of increase (he) were 0.12 and 1.13, respectively. The net reproductive rate was 240.44′ and the mean generation time was 28.63 days.
