• This study provides information about the life cycle of the predator Stethorus tridens Gordon (Coleoptera Coccinellidae), and its potential to control the pest Tetranychus bastosi Tuttle, Baker et Sales (Acari Tetranychidae). Life table parameters of S. tridens fed T. bastosi infesting physic nut (Jatropha curcas L.) were evaluated. The mean life cycle of S. tridens was 12.35 days and mean longevity was 57.1 days, with an average of 101.1/female. The life table parameters of S. tridens were: specific fertility came to a maximum of 2.49 eggs; survival probability: 0.92%; net reproduction rate: 53.05 individuals; average generation time: 17.09 days; intrinsic rate of growth: 0.23 females/day; finite rate of increase: 1.26 individuals/female; and population doubling time: 2.98 days. These results indicate that S tridens develops successfully when fed T. bastosi on J. curcas.
