| 摘 要： | 在室内测定了陈齿爪鳃金龟Holotrichia cheni Chang成虫对油橄榄、板栗和杨梅新鲜树叶的选择和取食反应。油橄榄与板栗和杨梅比较,陈齿爪鳃金龟显著趋向油橄榄树叶,而板栗与杨梅相比,则显著趋向板栗树叶(P<0.01)。陈齿爪鳃金龟成虫取食油橄榄、板栗、杨梅树叶12h后,平均排粪量分别为(203.0±104.8)mg、(100.6±76.6)mg和(8.0±9.6)mg,差异显著(P<0.05),且雄虫对油橄榄的平均取食量约为雌虫的2倍。油橄榄是陈齿爪鳃金龟的主要寄主。

| Abstract: | The feeding preferences of Holotrichia cheni Chang adults with regard to fresh leaves of olive,Chinese chestnut and red bayberry were tested experimentally.A significant preference for olive leaves over those of the other two plant species,and for Chinese chestnut leaves over those of red bayberry,was apparent（P0.01）.The amount of feces excreted after feeding for 12 h on olive,Chinese chestnut and red bayberry leaves was（203.0±104.8）mg,（100.6±76.6）mg and（8.0±9.6）mg,respectively.Furthermore,males produced approximately twice as much feces as females.The results indicate that olives are the primary host of H.cheni. |
