Abstract
The flea beetles Podagrica puncticollis Weise and Podagrica pallida Jacoby Halticidae – Coleoptera are among the important cotton pests in the Sudan. Some aspects regarding the morphology, biology ecology and control of these pests were studied. The taxonomic features by which the two species can be identified were given. The incubation period, fecundity life history were also worked out. Water was found an important factor determining egg laying and egg hatching. The two species showed two different population peaks, one during early stage of cotton growth, the second took place when the plants were maturing. The damage was common through the course of plant growth, more and severe on hairy varieties in the seedling stage correlated with the abundance of the pest. Control tests proved that seed dressing by Dieldrin and Birlane were the best treatment for checking the flea beetles.
