摘要

用c带分析了两种三棱蝽的精子发生。常染色体间带和端带是异翅目昆虫的共同特征。终端带证实了在全新中心染色体中异染色质优先位于端粒的假设。在精子发生过程中，雌雄同体的性染色体完全异色，雌雄同体的X染色体在正带和负带之间交替存在。

Heterochromatin patterns in triatomines of the genus Panstrongylus.

Spermatogenesis was analysed by C-banding in two species of triatomines, Panstrongylus megistus and P. herreri. Both species revealed interstitial and terminal bands in the autosomes, which is a common pattern in Heteroptera. The terminal bands corroborated the hypothesis that in holocentric chromosomes the heterochromatin is preferentially located at the telomere. The sex chromosomes in P. herreri were totally heterochromatic in spermatogenesis, and in P. megistus the X chromosomes alternated between positive and negative banding.
