abstract
Serangium parcesetosum is a predator of the whitefly (Bemisia tabaci), a major pest of cassava in Africa which causes crop yield reduction of up to 50% in susceptible cassava varieties as well as vectoring cassava mosaic disease (CMD) and cassava brown streak disease (CBSD). In order to explore the use of this predator in the sustainable management of this pest, a study was conducted to evaluate the population of Serangium parcesetosum in two agro-ecological zones of Uganda, namely; North Western Savannah Grassland (Lira) and the Kyoga Plains (Kamuli) in the first rains of 2017. Results revealed that both mean adult and larvae Serangium parcesetosum per plant were more abundant in Kamuli (4.92 and 11.75) as compared to Lira (0.39 and 0.51) respectively. Location and cassava age emerged as the main drivers of whitefly population which directly influenced the Serangium parcesesotum population.
