Internal reproductive organs of Cosmoclopius nigroannulatus (Hemiptera: Reduviidae)

Abstract

AbstrActthe internal reproductive organs of Cosmoclopius nigroannulatus males and females are described, illustrated and measured. no significant difference was registered among immature and reproductive structures of males and their aspect was also similar. However, in females noteworthy differences both in size and aspect were found.Keywords: reduvids, internal reproductive organs. resumo Descrição dos órgãos reprodutivos internos de Cosmoclopius nigroannulatus(Hemiptera, reduviidae) os órgãos internos de reprodução de machos e fêmeas de Cosmoclopius nigroannulatus são descritos, ilustrados e mensurados. não se registrou diferença significativa entre machos imaturos e reprodutivos quanto ao tamanho das estruturas, sendo o aspecto destas similar em ambos. Já nas fêmeas, constataram-se diferenças notáveis tanto no aspecto quanto no tamanho.Palavras-chave: reduvídeos, órgãos internos de reprodução.

Juvenile hormone–stimulated synthesis of acyl‐glycerols and vitamin E in female accessory sexual glands of the fire bug, Pyrrhocoris apterus L.

“…Like in the milkweed bug, Oncopeltus fasciatus (Dallas) (Bonhag and Wick, 1953), the excretory channels of AG lead to a posterior part of the genital chambre in females of P. apterus and in both species are of ectodermal origin (Merle, 1969). By contrast, the AG of a pentatomid bug, Perillus bioculatus, form groups around the lateral oviducts (Adams, 2001) and in a reduviid, Cosmoclopius nigroannulatus, the excretory channels lead between the common oviduct and genital chambre ( Jahnke et al, 2006).…”

Anatomy of male and female reproductive organs of stink bugs pests (Pentatomidae: Heteroptera) from soybean and rice crops

“…The units forming Heteroptera ovarioles generally consist of a terminal filament, tropharium, vitellarium, and pedicel (Davey 1958, 1959, Davey & Webster 1967, Ma & Ramaswamy 1987, Nijhout 1998, Szklarzewicz 1998, Lemos et al 2005, Jahnke et al 2006, Ozyurt 2013b. However, the number of ovarioles can vary even intraspecifically in response to reproductive strategy, seasonality, or resource availability (Wellings et al 1980, Tschinkel 1987, Stewart et al 1991.…”

“…Seven ovarioles were observed In O. insularis, C. ubica, and P. guildinii while this number varies from 8 to 14 in most Heteroptera (Grozeva & Kuznetsova 1992, Bunig 1994, Lalitha et al 1997, Lis 2003, Jahnke et al 2006, Ogorzalek 2007, 2009, Ozyrt et al 2013b. However, approximately 100 ovarioles have been observed in Palaecoccus fuscipennis (Szklarzewicz et al 2005), 300 have been observed in P. polonica (Szklarzewicz 1998), and 400 have been observed in Dysmicoccus coccus (Ramírez-Cruz et al 2008).…”

Ultrastructure of male reproductive system of Eurydema ventrale Kolenati 1846 (Heteroptera: Pentatomidae)

“…These tubule numbers are commonly found within Heteroptera and typical for pentatomids as in the E. ventrale. The number of the follicles varies widely between species and has taxonomic importance (Matsuda, 1976;Davis, 1956;Pendergrast, 1956;Kumar, 1969a;Kumar, 1969b;Lemos et al, 2005;Jahnke et al, 2006;Pap aček and Sold an, 2008;Rodrigues Agna et al, 2008;Wieczorek and Swiatek, 2009;Freitas et al, 2010;Karakaya et al, 2012;€ Ozyurt et al, 2013a€ Ozyurt et al, , 2013b€ Ozyurt et al, , 2014.…”
