中文摘要： 初步观察了中华蚊母树(Distylium chinense (Fr.) Diels)不同类型虫瘿的发生过程及致瘿虫生活史。结果表明，中华蚊母树的虫瘿有3种类型，分别为叶/枝上大型虫瘿、叶上泡状虫瘿和叶柄/果上球型虫瘿。三者均为单室封闭型，次生开口。经鉴定致瘿昆虫均为半翅目蚜科昆虫，其中叶上泡状虫瘿致瘿昆虫为蚊母新胸蚜Neothoracaphis yanonis Matsumura。该虫3月初在虫瘿内营孤雌生殖，繁殖2代，5月底前飞离出瘿。
英文摘要： Different types of insect galls on Distylium chinense (Fr.) Diels are described and the life history of the gall makers investigated. The results show that there were three types of insect galls; large galls on leaves or twigs, vesicular galls on leaves and spherical galls on petioles or fruit. All of these were single-chamber with a closed secondary opening. The gall makers were identified as insects of the Aphididae (Hemiptera), and the species in the vesicular galls was Neothoracaphis yanonis Matsumura which is in a state of semi-metamorphosis and parthenogenesis for two generations from March to May.
