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。 Indoors, adult Holotrichia cheni Chang adults were selected for the selection and feeding responses to the fresh leaves of olive, chestnut and bayberry. Compared with Chinese chestnut and Chinese bayberry, Olivoidea dorsalis showed a significant tendency toward Olive leaves, whereas chestnut showed a significant tendency toward chestnut leaves (P <0.01). The mean fecal excretion was (203.0 ± 104.8) mg, (100.6 ± 76.6) mg and (8.0 ± 9.6) mg, respectively (P <0.05, P <0.05) ), And the average male feeding on olive is about twice that of female. Olive is the main host of the clawed beetle.
