黑纹粉蝶Pieris melete Ménétriès生殖系统

【目的】研究黑纹粉蝶Pieris melete Ménétriès生殖系统的解剖学结构，以期发现更多的分类特征，为其所属类群乃至粉蝶亚科的系统发育分析提供依据。【方法】于2009-2010年夏季分别在浙江临安和陕西秦岭采集黑纹粉蝶成虫，在MODEL SZX2-ILLK型显微镜下观察雌虫和雄虫内、外生殖器的解剖结构，运用QImaging Retiga 2000R CCD数码相机进行照相，用图像叠加软件Automontage进行图像合成，描述其特征。【结果】黑纹粉蝶雌虫外生殖器包括交配囊及其附属结构、导精管、表皮突和肛突；内生殖器包括1对卵巢、1对侧输卵管、1根中输卵管、受精囊、附腺以及外生殖腔。雄虫外生殖器包括阳具、抱握器及其支持结构；内生殖器包括1个睾丸、2条输精管、1对贮精囊、开口于阳茎基部的射精管和附腺。【结论】黑纹粉蝶的卵巢两侧不对称，一侧的4根卵巢管直接合并，另一侧则是相邻的2根卵巢管先分别聚成一支，然后2支再聚合，与中输卵管相接。

Anatomy of the reproductive system of Pieris melete Ménétriès(Lepidoptera:Pieridae)

【Objective】 The anatomical structure of the reproductive system of Pieris melete Ménétriès(Lepidoptera:Pieridae) is studied and illustrated in this paper,aiming at providing more useful information for taxonomy and phylogeny of Pieris Schrank even Pierini.【Method】 Examined specimens were collected in Zhejiang Linan and Shaanxi Qinling in 2009-2010 summer,which were dissected by the stereomicroscope of MODEL SZX2-ILLK and photographed by the QImaging Retiga 2000R(CCD),then described and illustrated.【Result】 The male internal reproductive organ is composed of testis,vasa deferentia,seminal vesicle,accessory glands and ductus ejaculatorius.The male external genitalia consisted of aedeagus,vinculum and clasper.The female internal reproductive organ is composed of a pair of ovaries,lateral oviducts,common oviduct,spermatheca and accessory glands.The female genitalia include bursa copulatrix and associated parts,ductus seminalis,apophyses and papillae anales.【Conclusion】 The ovary is unsymmetrical:4 ovarioles jointed directly on one side,while on the other side,the two adjacent ovarioles linked separately,and these two connected with the lateral oviduct.
