【摘要】 竹子是一类重要的经济植物,在国民经济及人们日常生活中起着重要作用。蚧虫是寄生在竹子上的主要害虫类群之一,影响着我国竹产业的健康发展。因此,研究竹上的蚧虫具有重要意义。 本论文包括两个部分。 第一部分研究了中国竹类粉蚧科昆虫18属24种,详细描述了其显微特征,编制了分属、分种检索表,并绘制11种的形态特征图。 第二部分以中国竹亚科植物上的蚧虫6科40属127种为基础,分析了竹蚧的寄主广度、寄生部位和地理分布。结果表明:竹类蚧虫的寄主专化性程度较强;寄生在叶片上蚧虫种类最多;在国内各动物地理区的种类丰度依次为:华南区>华中区>西南区>华北区>蒙新区>青藏区>东北区;3/4的种类起源于东方区系。 此外,在广泛收集资料的基础上,列出了世界竹类植物上的粉蚧名录。更多还原

【Abstract】 Bamboo is a high-valued economic plant, which plays a very importantrole in our daily life. Scale insect is one of the major pest species groups which live on bamboos and prevents the national bamboo industry from healthy development. Therefore, to explore the scale insects on banboos is of great meaning.This paper includes two parts.The first part: The morphological characters of the mealybugs(24 species belonging to 18 genera) on bamboos in China were elaborately studied and 11 species among them were illustrated. Keys to the 24 species and 18 gengera were also given.Based on the catalogue of scale insects (127 species belonging to 40 genera and 6 families) living on bamboos, the second part has analyzed the host ranges, parasite parts and distribution of bamboo scale insects in China. The results show that: 1) bamboo scale insects are comparatively host-specific group; 2) leaves host most species of scale insects; 3) the species richness in zoogeographical region of China is: South-China Region > Central China Region > Southwest China Region > North China Region > Mengxin Region > Qiangzang Region > Northeast China Region; three quarter of scale species on bamboo in China originate from east Asia area.In addition, based on the extensive collection of data, it has listed the names of mealybugs on bamboos all over the world.更多还原
