Abstract
Since the pre-project assignment in January – March 1990 intensive pheromone trapping has been undertaken to the north and west. As is evident in Figure 1, the pest was not caught in Narok, S.Nyanza, Kisumu and Siaya in July nor the Rift Valley in the Naivasha - Gilgil - Nakuru area in October. In a survey to the north in May the insect was caught at many sites in Kitui Division. In Machakos Division fewer occurrences were recorded. None was trapped near or at Thika town. Low numbers have been caught sporadically in Nairobi suburbia.
