摘要
广东南雄烟区烟叶、莲藕、芋头、豆角、辣椒、茄子、花生等对斜纹夜蛾分布和生长发育的影响试验结果表明,斜纹夜蛾幼虫在不同作物上的分布数量多少依次为:莲藕>芋头>烟叶>花生>茄子>辣椒>豆角;斜纹夜蛾幼虫取食不同寄主植物的发育历期长短依次为:辣椒>花生>茄子>芋头>豆角>烟叶>莲藕,取食不同作物对幼虫质量、存活率、蛹质量均有明显的影响。
Effects of different host plants on the distribution and development of Spodoptera litura in Nanxiong Guangdong were reported in this paper. The results showed that, the distribution sequence of larvae on the plant is Nelumbo nucifera, Colocasia schott, Nicotiana tabacum, Arachis hypogaea, Solanum melongena, Capsicum annuum, Vigna unguiculata. When fed on different host plants, the order of development duration of larvae was Capsicum annuum, Arachis hypogaea, Solanum melongena, Clocasia schott, Vigna unguiculat, Nicotiana tabacum, Nelumbo nucifera. There are significant difference among the weight of larvae and pupae, and the survival rate.
