abstract

  • Sweetpotato weevils (Cyias puncticollis (Bohe.) and C. brunneus (Fabr.) Coleoptera: Apionidae) are the most important insect pests in South Nyanza, Kenya's principal sweetpotato-growing district. A pest of secondary importance is the sweetpotato butterfly (Acraea acerata (Hew.) Lepidoptera: Nymphalidae). Cultural central is currently the most promising component of an integrated pest management strategy for subsistence sweetpotato farmers in Kenya A survey of farmers' cultural practices in South Nyanza suggests that crop protection workers should concentrate their research and extension efforts on crop sanitation and the avoidance of adjacent planting of successive crops. The life cycle and behaviour of the sweetpotato weevils end butterfly should be explained to farmers, so that they better understand the insects' modes of dispersal and thus see the need for sanitation and adjacent planting.
