tailieunhanh - Field evaluation of attractive lures for the fruit fly Bactrocera minax (diptera: tephritidae) and their potential use in spot sprays in Hubei province (China)

The Chinese citrus fruit ßy, 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 ßy 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 signiÞcantly more adults than sugar-vinegar-wine mixture, torula yeast, and Jufeng attractant, in decreasing efÞciency order. In spot sprays those with H-protein bait killed signiÞcantly more female and male ßies within 40 min than those with sugar-vinegar-wine mixture, GF-120, Jufeng attractant, and the control. In addition, the total number of ßies 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. | Field evaluation of attractive lures for the fruit fly Bactrocera minax (diptera: tephritidae) and their potential use in spot sprays in Hubei province (China)
