|Abstract:||Fruit fly monitoring traps with male lures (cue-lure, methyl eugenol,
trimedlure, latilure) and food lure (torula yeast and BioLure) were maintained
on the island of Oahu for three years (2006–2008) at 40 sites, characterized as
rural or residential, with or without agriculture or feral forest in proximity. The
1.7 million flies collected belonged to species already known to be established in
Hawaii (Bactrocera cucurbitae, B. dorsalis, B. latifrons, and Ceratitis capitata);
no new invasive species were trapped, though the remotely possible presence of
sibling species nearly identical to B. dorsalis can’t be ruled out. B. cucurbitae
was predominant in leeward western Oahu and most abundant, in both rural and
residential areas, wherever agriculture was practiced nearby. B. dorsalis was
trapped in highest numbers in the windward northeastern portion of Oahu, and
the presence of adjacent forest increased captures in both residential and rural
environments. C. capitata was trapped in very large numbers at a coffee farm in
Waialua and was rare at all other sites.
