摘要
本文通过对日本黄脊蝗Patanga japonica(I.Bol.)、短角直斑腿蝗Stenocatantops mistshenkoi Will.和霍山蹦蝗Sinopodisma houshana Huang精子的比较,发现它们的精子的线粒体衍生体和中心粒侧体的超微形态结构十分相似,在精子发生过程中7、8两期精细胞线粒体衍生体周围微管的排数相一致。这3个种精子间的差异主要反映在外形头和尾的长度,线粒体衍生体的大小和纵峙数目以及中心粒侧体片数的不同方面。
The spermatozoa and spermatids of three species of Patanga japonica (I. Boi. ), Stenocatantops mistshenkof Will. and Sinopndisma houshana Huang are described in this paper. Although those are located in the different genera of Catantopidae, their spermatozoa and spermatids share the common characteristics, such as in the spermatozoa the mitochondrial deriyatives own the longitudinal cristae, and the centriolar adjuncts belong to the multilaminar complex. In the spermatids there are two rows of microtubules surrounding the mitochondrial derivatives at stage 7 and 8. The differential characteristics in the spermatozoa occur in their total form lengthes, dimensional size and the number of cristae for the mitochondrial derivatives and the number of laminae of the centriolar adjuncts.After comparison, an important fact has been found that the spermatozoa of the abovementioned species are the same type as those of the other species sperm of Catantopidae,which were described by Baccetti in 1987.
