Estudos anatômicos e histológicos sôbre a subfamília Triatominae (Heteroptera, Reduviidae): X. parte: Espermiohistogênese do Triatoma infestans

Abstract: No trabalho apresentado, descrevemos a evolução do espérmio maduro de triatoma infestans, iniciando-se a observação das transformações a partir dos espermídeos. Destacamos, em seguida, os principais resultados: 1. A histogênese dos espérmios é subdividida em 6 fases que se superpõem, parcialmente, a respeito do cronismo dos acontecimentos celulares: a) fase de translações (translações dos centríolos, mitocôndrios e do aparelho de GoLGI do pólo apical o pòlo basal da célula). b) Alongamento dos centríolos (form… Show more

“…2A). This structural organization is similar to that found in other insects (Barth, 1958b;Chapman, 1998), but the low number of testis follicles is an intriguing finding, since Hemiptera usually have four to seven testis follicles (Lemos et al, 1995(Lemos et al, , 2010Freitas et al, 2007bFreitas et al, , 2008. 2B).…”

“…The male accessory glands in insects are responsible for spermatophore production and produce some active peptides that stimulate ovary activation after mating, decrease female reception for mating and are bactericide . The number of male accessory glands varies among insects, but in Heteroptera there are about seven pairs (Barth 1958) contrasting with the single pair found in P. decempunctatus. In insects with many pairs of male accessory glands, different glands produce distinct substances.…”
