Studies on Trypanosoma rangeli Tejera, 1920: V - Developmental pattern in the alimentary canal of Rhodnius prolixus

open access: yesMemorias do Instituto Oswaldo Cruz, 1983
The morphological sequence of Trypanosoma rangeli development in the alimentary canal of Rhodnius prolixus, is described, with observation made in dissected guts from 6 hours to 45 days post-infection.

Behavioral fever response in Rhodnius prolixus (Reduviidae: Triatominae) to intracoelomic inoculation of Trypanosoma cruzi

open access: yesRevista da Sociedade Brasileira de Medicina Tropical
: INTRODUCTION: Behavioral fever is a response to infections with microorganisms observed in some poikilothermic animals. Rhodnius prolixus is involved in the transmission of two parasites: Trypanosoma cruzi (pathogenic for humans and transmitted in ...

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Calcitonin‐like diuretic hormone influences reproduction in adult female Rhodnius prolixus

open access: yesInsect Science, EarlyView.
Highlights • CT/DH‐like immunoreactivity is present in female reproductive tissues • CT/DH receptor transcripts are expressed in the fat body and ovaries • RNAi knockdown of CT/DH receptors reduces egg number and hatching rate • Rhopr‐CT/DH increases RhoprVg1 and RhoprVgR expression in ovaries in vitro • Rhopr‐CT/DH stimulates oviduct contractions in a

Microbial Odorant Detection Guides Drosophila Parasitoids Seeking Hosts in Fermenting Fruits

open access: yesAdvanced Science, Volume 13, Issue 39, 13 July 2026.
Yeast microbes in fermenting fruits attract both host flies and their parasitoid wasps. Female Leptopilina boulardi detect yeast‐emitted ethyl esters via two olfactory receptors, LbouOR167 and LbouOR136. A conserved residue, Leu159, is critical for binding these compounds, enabling female wasps to locate host‐rich habitats.

Identifying Health Centers in Honduras Infested with Rhodnius Prolixus Using the Seroprevalence of Chagas Disease in Children Younger than 13 Years. [PDF]

open access: yes, 2005
The objective of this study is to determine if a Chagas disease protocol starting with a serological survey is as reliable at identifying insect-infested areas as one using the gold standard entomological survey.
