Mean (±SE) daily captures of Bactrocera moluccensis (Perkins) in cue-lure traps maintained: A) in Papua New Guinea between November 1998 and February 2000, based on five trapping sites (n = 80, mean FTD = 2.35), and B) in the Solomon Islands (Guadalcanal Island) between April 1999 and August 2001, based on 11 trapping sites (n = 253, mean FTD = 1.50).
