摘要

Sweet potato is infested by many insect pests. Sweet potato weevil (SPW) Cylas formicarius (Fab.) is the important insect pest throughout the world, wherever it is grown. The weevil is managed by a package of practices together called integrated pestmanagement (IPM). In India, a few genotypes of sweet potato have shown durable resistance throughout 2006 to 2011. A new screening method of germplasm, volatile-assisted selection (VAS), was developed to identify resistance/susceptibility in sweet potatogenotypes based on the volatile chemicals that are released. Transgenic sweet potato was not successful at the field level. Farmers in Asia practice intercropping of sweet potato with ginger, bhendi, taro and yams to reduce the incidence of pests as well as to conserve soil moisture. Entomopathogenic fungi and nematodes are used successfully to control C. formicarius in the West and Latin America. Female sex pheromone (Z)-3-dodecen-l-ol (E)-2-butenoate has changed the pest dynamics in the field and hasbecome an important tool in C. formicarius IPM. It was used to monitor and trap male weevils, thus reducing the reproductive success of female weevils. A number of botanical pesticides are available and their use is limited in developed countries. A fewinsecticides that were used to control C. formicarius were banned in recent years in many countries and it is essential to identify new molecules with low or no persistence in tubers and soil with toxic effects on weevils. We reviewed the research doneon SPW during the last five decades to assess the management practices of SPW and to identify new strategies required to control the pest effectively and economically.
