Abstract

Descrição e Morfometria Ontogenética das Ninfas de Belminus herreri Lent & Wygodzinsky (Hemiptera: Reduviidae, Triatominae)

Description of nymphs and ontogenetic morphometry of Triatoma ryckmani Zeledón & Ponce, 1972 (Hemiptera: Heteroptera: Reduviidae: Triatominae)

“…The stridulatory sulcus of the nymphs acquires a shape of V, with papillae, tubercles and sensilla delimiting it, as previously observed in other nymphs of Triatominae, such as Linshcosteus karupus Galvão, Patterson, Rocha & Jurberg, 2002, Belminus herreri Len & Wygodzinsky, 1979, Triatoma vandae Carcavallo et al, 2002, Triatoma williami Galvão, Souza & Lima, 1965, Triatoma jurbergi Carcavallo, Galvão & Lent, 1998and Triatoma guazu Lent & Wygodzinsky, 1979Galvão et al 2005;rocha et al 2005;Silva et al 2005). Head shows many setigerous tubercles unevenly distributed in the first instar.…”

“…Head shows many setigerous tubercles unevenly distributed in the first instar. From the second to fifth instar there is a gradual organization of such tubercles, resulting in a different ornamentation for each instar (Silva et al 2003;rocha et al 2005;Silva et al 2005). The rostrum segments shows a unique and curious development in relation to the stridulatory sulcus.…”

Chrysomya megacephala (Fabricius, 1794) (Diptera: Calliphoridae) development by landmark-based geometric morphometrics of cephalopharyngeal skeleton: a preliminary assessment for forensic entomology application

“…By using regression analysis of the Procrustes coordinates and centroid size/log-transformed centroid size, the association between shape and size across different age groups was significant with moderate to high effect. This allometric effect has been reported in other organisms and the relationships vary and were usually high during ontogenesis (Rocha et al 2005;Scalici et al 2010;Strelin et al 2018). However, for future studies, we recommend using an equal amount of sample size between groups and to reassess the GM landmarks.…”

La première observation in natura de l’entomophagie dePanstrongylus geniculatus(Latreille 1811) hématophage vecteur de la maladie de Chagas (Hemiptera: Reduviidae)

“…Quelques espèces de Triatoma, les larves et adultes de Eratyrus mucronatus Stål 1859, de Belminus herreri Lent &Wygodzinsky 1979 (notamment sur d'autres Triatominae, alors qualifi é de cleptohématophagie) sont connus pour se nourrir occasionnellement sur d'autres insectes et arthropodes (Sandoval et al 2000;Schofi eld, 2000;Rocha et al 2005;Tartarotti et al 2006). Mais ce comportement est rarement observé dans la nature, plus souvent en élevage (incluant du cannibalisme).…”
