摘要

检测了雄性和雌性三角蝽成虫、侵染三角蝽和大圆线虫种(异翅目，三角蝽科)的三个唾液腺中Mg 2+ - atp酶的活性。D1和D2以双核为主，D3以单核为主，细胞核体积大，呈多倍体。检测到atp酶活性，特别是在常染色质和核仁中，该酶可能在转录过程中起作用。核膜中也有atp酶反应，它与核细胞质运输有关。这些特征表明高代谢和蛋白质合成，这对于唾液的产生和维持三角胺的噬血是必不可少的。

Mg 2+ -dependent ATPase activity in triatomine salivary glands (Heteroptera, Triatominae)

Mg 2+ -ATPase activity was detected in the three salivary glands of adult triatomines, males and females, of Triatoma infestans and Panstrongylus megistus species (Heteroptera, Triatominae). A predominance of binucleated cells in D1 and D2 and mononucleated in D3 was observed, with bulky and polyploidy nuclei. ATPase activity was detected, specifically, in euchromatin and nucleolus, where this enzyme probably acts in the transcription process. ATPase reaction was also evidenced in the nuclear membrane, which was associated with nuclear-cytoplasmatic transport. These characteristics indicate a high metabolism and protein synthesis, which must be essential to saliva production and in maintaining the hematophagy of triatomines.

期刊介绍： The journal Iheringia, Série Zoologia, edited by the “Museu de Ciências Naturais” of the “Fundação Zoobotânica do Rio Grande do Sul”, publishes original research findings in zoology with emphasis on taxonomy, systematics, morphology, natural history, and community or population ecology of species from current Neotropical fauna. Scientific notes will not be accepted for publication. Species lists without a taxonomic approach, or that are not the result of studies on the ecology or natural history of communities will not normally be accepted. The same applies to identification keys of groups of taxa defined by political boundaries. Authors wishing to inquire about the scope of the journal or the suitability of a particular topic are encouraged to contact the Editorial Board prior to submission. Furthermore, articles with a main focus on agronomy, veterinary, zootechny or other areas involving applied zoology will not be accepted. Its abbreviated title is Iheringia, Sér. Zool., which should be used in bibliographies, footnotes and bibliographical references and strips.
