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

Unravelling the biochemical aspects of the interaction between ticks and Leishmania using a tick cell line

open access: yesMedical and Veterinary Entomology, EarlyView.
Leishmania infantum propagated in IDE8 tick cell line in vitro. L. infantum reduces tick cell viability and induces reactive oxygen species production. Lipidic profile of IDE8 tick cell line is altered during Leishmania infection. Abstract Leishmaniasis comprises a group of vector‐borne neglected tropical diseases caused by species of the obligatory ...

Thermosensation and the TRPV channel in Rhodnius prolixus

open access: yesJournal of Insect Physiology, 2015
The thermal sense of triatomine bugs, vectors of Chagas disease, is unique among insects. Not only do these bugs exhibit the highest sensitivity to heat known in any animal up to date, but they can also perceive the infrared radiation emitted by the body of their warm-blooded hosts.

An atlas of plant selenium metabolism

open access: yesNew Phytologist, EarlyView.
Summary Selenium (Se) is not only a rare and toxic element but also an essential micronutrient for humans and animals that is often in short supply. Terrestrial plants do not require Se, but it can have growth‐promoting or negative effects, depending on the exposure level.

Gonadulin and Insulin‐Like Growth Factor Involved in Rhipicephalus microplus Reproduction

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 3, Page 285-295, March 2026.
Insulin‐like growth factor (IGF2) in ovaries of Rhipicephalus microplus partially engorged females. Ovaries from females at different feeding stages were used to detect IGF2. ABSTRACT Gonadulin and insulin‐like growth factor (IGF) are neuropeptides synthesized by the central nervous system (CNS) of arthropods.

Effects of proallatotoxins (precocenes) on the development and reproduction of Rhodnius prolixus: some data

open access: yesMemorias do Instituto Oswaldo Cruz, 1991
Proallatotoxins, and particularly preconcenes, are exceptionally promising models for studying Rhodnius prolixus physiology and for comparison with other natural compounds with anti-hormonal activities.

Comparative dissection of the peripheral olfactory system of the Chagas disease vectors Rhodnius prolixus and Rhodnius brethesi.

open access: yesPLoS Neglected Tropical Diseases, 2021
American trypanosomiasis, or Chagas disease, is transmitted by both domestic and sylvatic species of Triatominae which use sensory cues to locate their vertebrate hosts. Among them, odorants have been shown to play a key role.
