两种黄板诱捕不同品种油茶林害虫研究

Two Yellow Trap Board Trapping Pests in Different Varieties of Camellia oleifera

利用信息素黄板和普通黄板对7种油茶Camellia oleifera林内的害虫进行诱捕,掌握试验林内主要害虫的种类和数量。结果表明:在供试的油茶林内诱捕到了茶黄蓟马Scirtothrips dorsalis、八点广翅蜡蝉Ricania speculum、东方丽沫蝉Cosmoscarta heros和茶小绿叶蝉Empoasca pirisuga 4种油茶害虫。而信息素黄板和普通黄板2种黄板在诱捕茶黄蓟马、八点广翅蜡蝉、东方丽沫蝉和茶小绿叶蝉的数量上没有显著差异(P>0.05)。岑软2号油茶Cengruan 2林内诱捕的茶黄蓟马数量较陆川油茶C.vietnamensis、博白大果油茶C.gigantocarpa、岑软3号油茶Cenruan 3、越南抱茎油茶C.amplexicaulis、南荣油茶C.nanyongensis多,达到了1 502.8头/板,差异显著(P<0.05),而普通油茶林内诱捕到的茶黄蓟马数量较陆川油茶多,为1 141.6头/板。诱捕数量最少的为陆川油茶,为173.6头/板,差异显著(P<0.05);岑软2号油茶林内诱捕到的八点广翅蜡蝉较普通油茶、陆川油茶、岑软3号油茶和越南抱茎油茶多,为6.8头/板,差异显著(P<0.05);岑软2号油茶林内诱捕到的东方丽沫蝉的数量较越南抱茎油茶和南荣油茶多,为10.6头/板,差异显著(P<0.05);岑软2号油茶林内诱捕到的茶小绿叶蝉的数量较博白大果油茶和南荣油茶多,为9.2头/板,差异显著(P<0.05)。

This article used the pheromone yellow board and common yellow board to trap the pests in 7 Camellia oleifera,to master the species and number of main pests,the results can provide a reference for us to find out the resistance of different varieties of C.oleifera.The results indicated that 4 species of pests were trapped in C.oleifera,mainly includes Scirtothrips dorsalis,Cosmoscarta heros,Ricania speculum,Empoasca pirisuga.But there was no difference in the number of the two kinds traps board(P>0.05).The trapping number of the Scirtothrips dorsalis of Cengruan 2 were more than C.vietnamensis,C.gigantocarpa,Cenruan 3 and C.amplexicaulis(P<0.05),the trapping number of the Scirtothrips dorsalis of C.oleifera was more than C.vietnamensis(P<0.05),the lowest number of traps of C.vietnamensis(P<0.05).The trapping number of the Cosmoscarta heros of Cengruan 2 were more than C.oleifera,C.vietnamensis,Cenruan 3 and C.amplexicaulis(P<0.05).The trapping number of the Ricania speculum of Cengruan 2 were more than C.amplexicaulis and C.nanyongensis(P<0.05).The trapping number of the Empoasca pirisuga of Cengruan 2 were more than C.gigantocarpa and C.nanyongensis(P<0.05).
