【摘要】 <正> 刻蚜属 Kurisakia Takahashi是群蚜科Thelaxidae的一个小属,世界记载仅5种,都分布于东南亚。大都为害经济树木。本文记载5种刻蚜中,包括3新种,除铁道木刻蚜一种缺乏田间为害记录外,其余4种发生数量都很多,都能造成树木严重受害或卷叶。尤其是山核桃刻蚜是山核桃产区威胁性的大害虫。蚜虫可盖满嫩梢和幼叶,使幼叶更多还原

【Abstract】 The present paper deals with five species of Kurisakia Takahashi from China. Among them three species are considered as new to science.1.Kurisakia sinocaryae Chang sp. nov. (fig. 1)2.Kurisakia sinoplatycaryae Chang sp. nov. (fig. 2)3.Kurisakia yunnanensis Chang sp. nov. (fig. 3)4.Kurisakia guerciphila Takahashi5.Kurisakia onigurumi (Shinii) Descriptions of new species, Kurisakia sinocaryae Chang sp. nov.Apterous viviparous female, Differs sharply from any other congeneric ones by tarsi with first segment bearing 7-9 setae (at most 7 in congeneric ones) ; siphun-culus situated in cluster of 14-17 setae on abdominal segment VI (at most 14) ; cauda with 14-18 setae (at most 14) ; and abdomen with 8 th segment bearing 24-28 setae (at most 12) . Alate viviparous female, Differs from them also, by antennal segments with more sensoria and anal plate with 18-19 setae (at least 21 in the congeneric ones).Syntype, 23 apterous viviparous females, 28 alate viviparous females, April 30, 1973 & May 11, 1975, West Tianmushan, Zhejiang, by Zhou Yang-kuo, Zhong Tie-sen and Chang Guang-shyue.Host plant, Cary a cathayensis Kurisakia sinoplatycaryae Chang sp. nov.This species differs sharply from any other congeneric ones, (1) In apterous viviparous female, body corrugated dorsally and hind tibia with setae as long as width of the tibia. (2) In alate viviparous female, cauda distinctly knobbed and constricted at extreme base.Syntype, 27 apterous viviparous females,14 alate viviparous females,May 24 & June 3, 1975, Hangzhou, Zhejiang, by Zhong Tie-sen & Chang Guang-shyue.Host plant, Platycarya strobilacea. Kurisakia yannanensis Chang sp. nov.The new species is related to Kurisakia querciphila Takahashi or K. onigu-rumi (Shinji) in general pattern, but differs therefrom by 3rd antennal segment with 17-18 setae (at least 21 in the latter) ?abdominal segmentsⅤ-Ⅶ with transverse bars, not fused into bands; 6th abdominal segment with 3-6 marginal setae (at least 6); 8th abdominal segment with 8 setae (at least 11) and siphunculus situated in cluster of 5-8 setae on abdominal segment VI (at least 7).Syntype. 16 alate viviparous females, May 8,1964, Mengla, Yunnan,by Chang Bao-lin.Host plant, Cassia stamea.The type specimens are kept in the Insect Museum of the Institute of Zoology, Academia, Sinica.更多还原
