From conversations that the writer has had, it would appear that this thrips (identified by Mr. R. S. Bagnall as Heliothrips indicus, Bagn.) has been known on the Gezira cotton for about three years, and is popularly called “dry asal” in contradistinction to the work of the “asal fly” (Aphis sorghi, Theo.) The natives have been acquainted with this insect for some time. The reason suggested for the enormous damage done by itis that the cotton is too scattered, and it is stated that if cotton were cultivated in larger blocks, the thrips might be viewed with equanimity.
