Host Range

Bactrocera caryeae has been recorded on hosts from six families. These include:

  • Anacardiaceae
  • Lecythidaceae
  • Malpighiaceae
  • Myrtaceae
  • Rutaceae
  • Sapotaceae

For a full list of recorded species see Allwood et al. 1999.

Major commercial hosts:

  • Citrus species (citrus)
  • Mangifera indica (mango)
  • Psidium guajava (guava)

Similar species

Bactrocera caryeae is similar to the Australian B. endiandrae but differs in having dark anteromedial corners on the postpronotal lobes, very narrow vittae, very narrow anal streak, dark fore tibia and dark apical spots on all femora.

It is similar to the exotic B. kandiensis, but differs in having a wraparound T (instead of a defined T) on the abdomen.

Pest Status

  • Exotic
  • Bactrocera caryeae occurs in very large populations in many fruit growing areas of southern India and is probably responsible for much of the damage generally attributed to Bactrocera dorsalis.
