猕猴桃属植物Actinidia spp,自然分布于中国的亚热带地区。对萼猕猴桃A.valvata的花芽受Pseudasphond ylia 瘿蚊属一未知种的寄生而形成花芽虫瘿,这种花芽瘿由于近年来在制药工业上的应用而受到重视。在中国中南地区研究对萼猕猴桃—瘿蚊的相互关系过程中,我们的记载表明该造瘿昆虫在一定情形下可能改变其寄主植物的雌雄异株之生殖模式。野外调查与实验证明寄主植物受寄生而形成虫瘿的比例很高。但虫瘿密度却于不同沟谷间,或同一沟谷内不同植株间有异。在二条沟谷内,92％和75％植株分别被寄生,而在第3条沟谷内没有植株受寄生。受寄生的雄性植株只产生虫瘿,而受寄生的雌性植株则产生正常果与虫瘿。有迹象显示当寄主植株有虫瘿形成时其正常果数量也更多。作者认为这可能是昆虫诱导功能上雌雄异株植物形成雄性异株雌雄同株之生殖模式的少数例子 Actinidia spp, Actinidia spp naturally distributed in China’s subtropical regions. The flower bud of A. valvata of the calyx kiwifruit is parasitized by an unknown species of the genus Pseudasphond ylia to form the flower bud grudge that has been valued by the pharmaceutical industry in recent years. In the study of the interrelationship between Calyx japonica and gall midge in central and southern China, our records indicate that under certain conditions, the louse may alter the reproductive pattern of the dioecious plants of its host plant. Field investigations and experiments show that host plants are parasitic and form a high proportion of galls. But the insect density is in different valleys, or different plants within the same valley vary. In the two valleys, 92% and 75% of the plants were parasitized, respectively, while no plants were parasitic in the third valleys. Parasitic male plants produce only galls, while parasitic female plants produce normal fruits and galls. There are indications that the number of normal fruits is more when the host plant has galls forming. The authors suggest that this may be a few examples of reproductive patterns that the insect induces to functionally form hermaphrodite monoecious plants on hermaphrodites
