HOST PLANTS: Its known host range includes 49 host species in 32 genera and 22 families. The following list covers published host plants from surveys in Tonga, Samoa and French Polynesia: Detailed host list.
BIOLOGY: Adults mate in late morning to early afternoon, when light intensity is highest. Life history and rate of development were studied in Samoa, where colonies are maintained. Heat tolerance studies were completed in Samoa. Attempts to rear the species in Tonga have had limited success.
MALE LURE: Cue-lure.
QUARANTINE SURVEILLANCE: Cue-lure trapping and regular host fruit surveys of high risk species, especially guava, mango, Tahitian chestnut, Syzygium apples and tropical almond.
OPTIONS FOR RESPONSE (If newly discovered in a country): Increased trapping, increased host fruit sampling, restriction of fruit movement, protein bait spraying.
