不同类型诱捕器在海南白沙茶园的诱捕效果

Trapping Effect of Different Traps in Baisha Tea Plantation of Hainan Province

在海南白沙五里路有机茶园和芳香村茶园对茶园斜纹夜蛾、甜菜夜蛾和茶小绿叶蝉3种不同类型的害虫进行监测防控,观察2种不同类型茶园不同类型诱捕器对3种类型茶树害虫的诱捕效果。同时探究不同类型诱捕器对茶园不同害虫诱捕效果的影响。在2021年6—12月,在五里路有机茶园斜纹夜蛾共计发生4代,甜菜夜蛾共计发生3代,茶小绿叶蝉共计发生4代。在芳香村茶园斜纹夜蛾共计发生5代,甜菜夜蛾共计发生4代,茶小绿叶蝉共计发生3代。诱捕斜纹夜蛾时,船形诱捕器(P=0.001)>三角形诱捕器(P=0.002)>桶形诱捕器(P=0.002)的诱捕效果;对甜菜夜蛾诱捕时3种诱捕器均未出现显著差异,说明诱捕器类型对茶园甜菜夜蛾无影响。诱捕茶小绿叶蝉时,船形诱捕器(P=0.001)>三角形诱捕器(P=0.001)>桶形诱捕器(P=0.000)的诱捕效果。

Monitoring and control of Spodoptera litura Fabricius,Spodoptera exigua Hiibner and Empoasca pirisuga Matumura were carried out in Organic Tea Garden of Wulilu and Fangxiangcun Tea Garden in Baisha County,Hainan Province,to observe the trapping effect of different traps in two different types of tea gardens on three types of tea pests.At the same time,the effect of different traps on trapping different pests in tea garden was studied.From June to December,4 generations of Spodoptera litura,3 generations of Spodoptera exigua and 4 generations of Empoasca pirisuga occurred in the Organic Tea Garden of Wulilu,2021.There were 5 generations of Spodoptera litura,4 generations of Spodoptera exigua and 3 generations of Empoasca pirisuga in Fangxiangcun tea garden.When trapping Spodoptera litura Fabricius:boat trap(P=0.001)>triangle trap(P=0.002)>barrel trap(P=0.002),there was no significant difference among the three traps,the results showed that trap type had no effect on Spodoptera exigua Hiibner in tea garden.When trapping Empoasca pirisuga Matumura,the trapping effect of boat-type trap(P=0.001)>triangle trap(P=0.001)>barrel trap(P=0.000)was studied.
