The efficacy of GF-120 NF Naturalyte Fruit Fly Bait in combination with field sanitation was assessed as a control for female oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), in papaya (Carica papaya L.) orchards in Hawaii. Three different bait spray regimes were evaluated: every row (high use of the bait), every fifth row (moderate use), and every 10th row (low use). Orchard plots in which no bait was applied served as controls. For five of the seven biweekly periods that followed the first bait spray, trapping data revealed significantly fewer female B. dorsalis captured in plots subject to high and moderate bait use than in control plots. Differences in incidence of infestation among treatments were detected only by the third (12 wk after first spray) fruit sampling with significantly fewer infested one-fourth to one-half ripe papaya fruit in plots subject to high and moderate bait use than in control plots. Parasitism rates by Fopius arisanus (Sonan) (Hymenoptera: Braconidae) were not negatively affected by bait application. Results indicate that foliar applications of GF-120 NF Naturalyte Fruit Fly Bait either to all rows (every other tree), or to every fifth row (every tree) in combination with good sanitation can effectively reduce infestation by B. dorsalis in papaya orchards in Hawaii.
评估了GF - 120 NF天然果蝇诱饵与田间卫生措施相结合，作为夏威夷番木瓜（番木瓜属）果园中东方果实蝇（橘小实蝇，亨德尔）（双翅目：实蝇科）雌蝇防治方法的效果。评估了三种不同的诱饵喷雾方案：每行（诱饵高用量）、每五行（中等用量）和每十行（低用量）。未施用诱饵的果园地块作为对照。在首次诱饵喷雾后的七个双周时间段中的五个时间段，诱捕数据显示，诱饵高用量和中等用量地块捕获的橘小实蝇雌蝇明显少于对照地块。仅在第三次（首次喷雾后12周）果实采样时才检测到处理间侵染发生率的差异，诱饵高用量和中等用量地块中受侵染的四分之一至二分之一成熟番木瓜果实明显少于对照地块。阿里山潜蝇茧蜂（索南）（膜翅目：茧蜂科）的寄生率不受诱饵施用的负面影响。结果表明，在夏威夷番木瓜果园中，将GF - 120 NF天然果蝇诱饵叶面喷施于所有行（每隔一棵树）或每五行（每棵树）并结合良好的卫生措施，可有效减少橘小实蝇的侵染。
