The status of pink boll worm in the Gezira, Sudan, with special reference to variety of cotton and sowing date (Lepidoptera:Gelechiidae)



The status of pink boll worm in the Gezira, Sudan, with special reference to variety of cotton and sowing date (Lepidoptera:Gelechiidae)



Bulletin de la Societe Entomologique d' Egypte 55: 105-123



The author reviews and discusses the extent of the damage caused to cotton in the Gezira region of the Sudan by Pectinophora gossypiella (Saund.) and the measures taken since the 1930's to limit the intensity of infestation. Damage has remained at a constant and fairly low level for some 30 years. Areas adjacent to the Blue Nile are those most heavily infested. The crop is normally sown in the first two weeks of August, and infestation begins as soon as flower buds are present.
