Abstract
Abstract The population behaviour of flea beetles (Podagrica uniforma and Podagrica sjostedti) on the common okra (Abelmoschus esculentus) were observed at six different spray regimes of Cypermethrine insecticide applied 60 g/ha a.i. Podagrica uniforma was observed to be more abundant than P. sjostedti. Spraying once every two weeks was found to be optimal while once‐weekly spraying showed a highly significant reduction in the population of the flea beetles. The yield response of okra was related to the population of beetles on the plant and was optimum at bi‐weekly spray regime, while an exceptionally high yield was observed under a twice‐a‐week spray regime of cypermethrine.
