  • Narrow distribution. Southeast Asia, Oceania. On mango. There are two kinds of leafhoppers. Important pests.
  • Adults dark brown, 4-5 mm, wedge shaped, breeding in flowers or in flowers and new leaf flushes. They cause flowers to brown and dry; and their honeydew excreta promotes black fungal growth on the leaves.
  • Spread long distance via the nursery trade.
  • Cultural control: none recommended.
  • Chemical control: use synthetic pyrethroids or dimethoate. In Australia, two sprays are applied 7 days apart before flowering (reducing risk to pollinators). Dimethoate is sprayed or injected. (In Australia, dimethoate has been under review since mid-2015. It is no longer allowed for home garden use.)
