Development and testing of an integrated pest management technique to control sweet potato weevil
Screening of over 1200 sweet potato accessions for resistance to the sweet potato weevil, Cylas formicarius (F.), failed to find any usable level of resistance for breeding purposes. Environment seems to play a dominant role in determining many sweet potato characters including weevil and host-plant interaction, making the use of weevil-resistant cultivar to control this pest potentially difficult. An integrated pest management (IPM) was therefore developed at AVRDC, which emphasizes the use of crop rotation, control of alternate Ipomoea spp. host from borders and surrounding empty areas, frequent hilling up of plants, and use of a female sex pheromone to continuosly trap weevil males from planting to harvest. This IPM, which has been successfully tested on farmers' fields in Taiwan, is now being promoted elsewhere where the insect is a serious pest.
