Pacific Pests, Pathogens and Weeds

Summary

  • Narrow distribution. Common in Pacific island countries on wide range of crops, including ginger, chillies, eggplant, kava, passionfruit, root crops.
  • Larvae burrow into roots, stems and storage organs.
  • Adult weevil and West Indian sweet potato weevil (WISPW) similar. Ginger weevil covered in fine scales, with no clear white pattern on wing cases; WISPW with thinner scales and clear white markings on the wing cases (see Fact Sheet no. 119).
  • Cultural control: check planting material for carry-over larvae; treating ginger and yams for nematodes (hot water at 51°C for 10 mins) will kill weevils; check at harvest and avoid storing infested roots, corms, tubers.
  • Chemical control: thiram/latex mixture painted on passionfruit cankers (Samoa). Possibly, dipping planting materials in imidacloprid.
