Effects of starvation on the olfactory responses of the blood-sucking bug Rhodnius prolixus [PDF]

open access: yes, 2013
Blood-sucking insects use olfactory cues in a variety of behavioral contexts, including host-seeking and aggregation. In triatomines, which are obligated blood-feeders, it has been shown that the response to CO2, a host-associated olfactory cue used ...

Exploiting triatomine behaviour: alternative perspectives for their control [PDF]

open access: yesMemórias do Instituto Oswaldo Cruz, 2009
Living in close association with a vertebrate host and feeding on its blood requires different types of adaptations, including behavioural adjustments. Triatomines exhibit particular traits associated with the exploitation of their habitat and food sources and these traits have been the subject of intense analysis.

Behavior of triatomines (Hemiptera, Reduviidae) vectors of Chagas' disease. II. Influence of feeding, lighting and time of day on the number of mating, mating speed and duration of copulation of Panstrongylus megistus (Burm, 1835) under laboratory conditions

open access: yesMemorias do Instituto Oswaldo Cruz, 1986
To determine in influence of feeding, lighting and time of day on the copulating behavior of Panstrongylus megistus, 480 insect pairs were divided into four groups of 120 each and tested in the following respective situations: without food deprivation (F.

Synthesis and Evaluation of the First Generation of Glycosylated Nucleoside Analogues as Potential Inhibitors of the Base J Metabolism in Kinetoplastid Parasites

open access: yesChemistry – A European Journal, Volume 32, Issue 10, 9 March 2026.
Novel analogues of the kinetoplastid‐specific DNA base J unlock a new way to target parasite epigenetic regulation. Some compounds selectively inhibit Leishmania and Trypanosoma species without harming human cells, revealing a promising route toward innovative antiparasitic therapies.

Artificial intelligence‐powered microscopy: Transforming the landscape of parasitology

open access: yesJournal of Microscopy, Volume 301, Issue 2, Page 280-329, February 2026.
Abstract Microscopy and image analysis play a vital role in parasitology research; they are critical for identifying parasitic organisms and elucidating their complex life cycles. Despite major advancements in imaging and analysis, several challenges remain. These include the integration of interdisciplinary data; information derived from various model

Possible absence of attraction to odor in Panstrongylus megistus (Hemiptera: Reduviidae) under laboratory conditions

open access: yesMemorias do Instituto Oswaldo Cruz, 1994
We tested the attraction of Panstrongylus megistus odor under laboratory conditons, between males and females of this species and by individuals of each sex on recently fed virgin couples.
