BIOLOGY: Not yet studied.
ECONOMIC IMPORTANCE: It infests 13-45% of guavas in the Central Province and up to 9% of oranges in the Highlands of Papua New Guinea.
MALE LURE: Cue-lure.
QUARANTINE SURVEILLANCE: Cue-lure trapping and regular host fruit surveys of guava.
OPTIONS FOR RESPONSE (If newly discovered in a country): Increased trapping, increased host fruit sampling, restriction of fruit movement, protein bait spraying, male annihilation.
CONTROL: Fruit bagging, protein bait spraying, destruction of fallen and overripe fruits, early harvest of mature green fruits.
