金沙江干热河谷区芒果青枣园橘小实蝇发生规律与防治

Occurrence Regularity of Bactrocera dorsalis(Hendel)in Mango(Mangifera indica L.)and Green Jujube(Zizyphus mauritiana)Orchards in the Dry-Hot Valley of Jinsha River and Its Control

为了掌握金沙江干热河谷区芒果园和青枣园橘小实蝇的发生规律,2018年在云南省元谋县苴林基地选择10 a生芒果园和5 a生青枣园采用实蝇粘胶板和性诱剂开展橘小实蝇的发生规律和诱捕效果研究。结果表明:元谋县芒果园和青枣园橘小实蝇种群发生的高峰期分别在7月上旬—8月下旬和6月下旬—8月上旬,实蝇粘胶板和性诱剂的诱捕效果显著高于蓝色和黄色粘胶板,可用于果园橘小实蝇的监测与诱杀。

In order to explore the occurrence regularity and trapping effect of Bactrocera dorsalis(Hendel)in mango(Mangifera indica L.)and green jujube(Zizyphus mauritiana)orchards in the dry-hot valley of Jinsha River,the monitoring and trapping experiment was conducted with 3 kinds of sticky boards and a sex attractant methyleugenol in a 10-year-old mango orchard and a 5-year-old green jujube orchard in Zuolin base of Yuanmou County,Yunnan Province in 2018.The results showed that the peak period of onset of Bactrocera dorsalis population was from early July to late August in mango orchards,and from late June to early August in green jujube orchards.The trapping effects of fruit fly sticky trap and sex attractant were much better than those of yellow sticky boards and blue ones,which could be used to monitor and trap Bactrocera dorsalis(Hendel)in orchards.
