The Chinese citrus fruit fly, Bactrocera minax (Enderlein) is a univoltine Tephritidae pest that infests Citrus species. Field trials were conducted in 2010 to determine the potential use of a lure based on enzymatical-hydrolyzed beer yeast as liquid bait (hereafter named H-protein bait) for B. minax in the Hubei province, China. In a citrus orchard, we compared the attractiveness among aqueous solutions of H-protein bait, GF-120 fruit fly bait, sugar-vinegar-wine mixture, torula yeast, and Jufeng attractant when used in traps and in spot sprays, that is, lures used in combination with the insecticide trichlorphon. The H-protein bait was the most attractive lure in traps, ensnaring significantly more adults than sugar-vinegar-wine mixture, torula yeast, and Jufeng attractant, in decreasing efficiency order. In spot sprays those with H-protein bait killed significantly more female and male flies within 40 min than those with sugar-vinegar-wine mixture, GF-120, Jufeng attractant, and the control. In addition, the total number of flies killed by H-protein bait during the spot spray duration was higher than other treatments. Our results demonstrated that the H-protein bait may be a useful tool in citrus orchards in China to monitor B. minax populations as well as to manage this pest when used in spot sprays.
中国的柑橘实蝇，Bactrocera minax（Enderlein）是一种单化的实蝇科害虫，它侵害柑橘属植物。2010 年进行了田间试验，以确定基于酶解啤酒酵母的诱剂作为液体诱饵（以下简称 H-蛋白诱饵）在中国湖北省用于 B. minax 的潜在用途。在柑橘园中，我们比较了 H-蛋白诱饵、GF-120 实蝇诱饵、糖-醋-酒混合物、酵母和橘丰引诱剂的水溶液在诱捕器和点状喷雾中的吸引力，即与杀虫剂三氯磷联合使用的诱剂。H-蛋白诱饵在诱捕器中最具吸引力，诱捕的成虫明显多于糖-醋-酒混合物、酵母和橘丰引诱剂，按诱捕效率递减排列。在点状喷雾中，H-蛋白诱饵在 40 分钟内杀死的雌、雄蝇数量明显多于糖-醋-酒混合物、GF-120、橘丰引诱剂和对照。此外，H-蛋白诱饵在点状喷雾期间杀死的蝇总数高于其他处理。我们的结果表明，H-蛋白诱饵可能是中国柑橘园中监测 B. minax 种群以及在点状喷雾中管理这种害虫的有用工具。
