甲基丁香酚和蛋白饵剂对海南杨桃园橘小实蝇诱控效果研究

Trapping Effect of Methyl Eugenol and Protein Bait on Bactrocera dorsalis (Hendel) in Hainan Carambola Orchard

于2010年6～9月采用甲基丁香酚诱杀雄成虫和蛋白饵剂诱杀雄、雌两性成虫的方法,开展了海南杨桃园橘小实蝇种群动态与诱控效果的研究。结果表明:橘小实蝇成虫发生高峰在7月中下旬,与杨桃1造果成熟期相吻合;橘小实蝇的种群密度与杨桃果实被害率明显呈正相关。表明采用诱杀两性成虫与及时处理落果等农业措施相结合的技术防治杨桃园橘小实蝇的效果显著,在不套袋和不施用农药的情况下2造杨桃保果率达81.3%。

The population dynamics and control effect of Bactrocera dorsalis（Hendel） in Hainan carambola orchard were studied from June to September in 2010.The method of methyl eugenol trapping male adults and protein bait trapping male and female adults of the pest were used.The results showed that the peak of the oriental fruit fly adults appeared from middle to late of July and it was related to the first fruit developing period of carambola.There was obviously a positive correlation between population density of the pest and damage rate of fruits.It indicated that the effect of controlling B.dorsalis in carambola orchard was significantly using the technology of trapping male and female adults combined with agricultural measures,such as treatment of drop fruits on time.The protective fruit rate for the second harvest time of carambola was 81.3%under the condition of fruit not bagged and not use with pesticides.
