Pacific Pests, Pathogens and Weeds


  • Worldwide distribution. In tropics and sub-tropics. On cassava, okra, papaya, sweetpotato, tomato, eggplant, beans, taro, bele, cucumber, squash, other cucurbits, and ornamentals
  • Common on under surface of leaves of taro, eggplant, bele, cassava and many others, especially when dry.
  • Mites have needle-like mouthparts and suck sap from leaves causing white speckling on top surfaces. Later, leaves turn yellow and die early. Webs occur.
  • Mites spread in wind and on plant parts.
  • Natural enemies: predatory mites, ladybird beetles, lacewing larvae, pirate bugs, big-eyed bugs and predatory thrips.
  • Cultural control: preserve natural enemies by not using insecticides; spray underside of leaves with water; mulch plants to preserve water in droughts.
  • Chemical control: soap, white or horticultural oils, wettable sulphur; abamectin; alternatively, difocol or synthetic pyrethroids, but they will kill natural enemies.
