Edible hosts common names. Acerola, cashew, common guava, custard apple, giant granadilla, Japanese persimmon, Malay-apple, mango, nectarine, papaya, peach, plum, pomegranate, pomelo, rose-apple, soursop, starfruit, strawberry, strawberry guava, sugar-apple, Surinam cherry, tropical almond, white mulberry, wine grape.

Biology. Adults mate during the day ( Mille 2010). Under laboratory conditions, eggs hatch after 2.25 days, larval development takes about 10 days and pupal stage lasts nine days ( Mille 2010). This species is most commonly trapped in rural areas and rainforest, rather than in village and suburban environments, unlike B. tryoni and B. curvipennis ( Amice and Sales 1997a) . Monthly trapping data illustrated on Figure 125 .

Notes. Heat tolerance of immature stages was investigated in New Caledonia (Sales et al. 1997a). Dacus virgatus Coquillett 1910 , designated as a junior synonym of B. psidii by Malloch (1931), is actually a synonym of B. facialis .
