The pollination ecology of Corydalis sheareri var. bulbillifera (Papaveraceae),a spring flowering perennial herb, was studied over a 3 year period in Yue lu Mountain of Changsha.Our results show that this species is facultatively autogamous and its mating system deponds on the weater during the blooming season.Its autogamy adapts to rainy weather in which the pollinators are not available. The innate factors responsible for its autogamy are cleisto pollination, self compatibility and connection of the inner petals. On fine days the cleisto pollination becomes secondary pollen prerentaion in cross pollination. The pollinator is Colletes cunicularis of which the pollination is xenogamy. After the fertilization, the corolla remains showy and viability of fhe pollens does not decline. In an attempt to explain auch a phenomenon.We present two nonexclusive hypotheses: the pollinator attracion hypothsis and the male function hypothesis.

连续3年的野外观察和室内实验结果表明:珠芽紫堇(Corydalisshearerivar.bulbilif-eraHand.-Mazz.)的有性生殖为兼性自花受精.其自花受精是对开花期间持续降雨导致传粉者限制的适应.保证自花受精的内部因素有闭花传粉、自交亲和及内轮花瓣顶端合生.晴天,闭花传粉则变为异花传粉中的花粉次级呈现.其传粉昆虫是柳分舌蜂(Coletescurnicularis),传粉主要发生在异株异花间.山小地花蜂(Panurginusmountains)为蜜腺抢劫蜂,干扰传粉者的采访.受精后花冠仍不凋谢,花粉生活力也无明显下降,持续时间约占整个花期的1/4至1/3.笔者为了解释这一特殊现象,提出了两个互不排斥的假说:吸引假说和雄性功能假说

This paper describes a new species, Coelopencyrtus claviger, collected from Yichun, Heilongjiang province, which is also the first record of the genus Coelopencyrtus Timberlake to China. The type specimens are deposited in the Department of Plant Protection, Zhejiang Unversity.

突唇跳小蜂属全世界已知29种,分布于世界各地,寄生膜翅目的木蜂科Xylocopi-dae、蜜蜂科Apidae和叶舌花蜂科Hylaeidae的幼虫,行多胚生殖。我国过去未见报道。本文报道从黑龙江伊春采集的突唇跳小蜂属1新种,即锤角突唇跳小蜂,Coelopen-cyrtusclaviger,sp.nov.,对新种进行了详细描述,并附特征图。本文也是突唇跳小蜂属在我国分布的首次记录。模式标本存放在浙江大学植物保护系。锤角突唇跳小蜂Coelopencyrtusclaviger,新种(图1~4)标本记录:正模♀,黑龙江伊春(47°42′N,128°54′E),1981-Ⅶ,金丽元,原始记录寄主为落叶松毛虫卵(?),850218;副模4♀♀,同正模。鉴别特征:本种与CoelopencyrtusarenariusErdoes很相似,主要区别是:1)触角棒节长为宽的1.4倍,索节第3~4节上有感觉孔,后者棒节长为宽的2.0倍;索节第3~4节无感觉孔;2)上颚明显长,后者上颚短;3)中足胫节末端、各足跗节第1~4节浅黄白色,第5节褐色,产卵管黑色,后者各足及产卵管均为褐色。
