Abstract
The relative importance of Heteroptera and the bollworms, H. armigera and Earias spp., as sources of crop loss in cotton in Eastern Uganda are discussed. It is apparent that the importance of bollworms especially, H. armigera, in causing loss of early crop has been understimated in the past owing to the more spectacular symptoms caused by T. vosseleri. T. vosseleri and other Heteroptera. it is suggested, are an impOIitant source of "recovery crop" loss. The relative importance of bollworm may have been increased by the earlier planting date for cotton now recommended. The increases of yield obtained with early planted sprayed cotton, in recent years is due to control of both bollworm and T. vosseleri, but especially of the former.
