Bactrocera atrisetosa (Perkins)
Male B. atrisetosa (Photo: S. Wilson) DISTRIBUTION: Restricted to mainland Papua New Guinea. Because it is not attracted to male lures, limited distribution records are based on flies bred from collected fruits in Central, Oro, Morobe and Eastern Highlands Provinces.
HOST PLANTS: This species has been reared from 8 host species in 7 genera and 3 families, and is mainly associated to cucurbits:

ECONOMIC IMPORTANCE: A major pest of Cucurbitaceae in the Central Province.
MALE LURE: This species does not respond to male lures.
QUARANTINE SURVEILLANCE: Regular host fruit surveys of high risk hosts (cucumber and zucchini).
OPTIONS FOR RESPONSE (If newly discovered in a country): Increased host fruit sampling, restriction of fruit movement, protein bait spraying.
CONTROL: Protein bait spraying, destruction of fallen and overripe fruits.
