Extract

One of the most important pests of rain-grown cotton in the Sudan is the genus Dysdercus (Pyrrhocoridae) of the Hemiptera Heteroptera. Upon the introduction of cotton into the southern provinces of the Sudan, these insects appeared in great numbers, and in certain districts threatened to render impossible the growing of the crop. In 1926 work was started on the bionomics and control of the cotton-stainers by Cowland & Ruttledge, who were working respectively in the Nuba Mountains and the Fung provinces. Later the crop in the Nuba Mountains proving to be the more important of the two, the study of these insects was confined to that region. Mr. Ruttledge followed Mr. Cowland as entomologist in the Nuba Mountains, and the writer followed Mr. Ruttledge in 1928. The results of the preliminary investigations of Cowland & Ruttledge formed a valuable base from which the writer continued the work.
