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

Medical and Veterinary Entomology, Volume 40, Issue 2, Page 350-359, June 2026.
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 ...

Conkazal‐M1 from the MKAVA family of conotoxins: A dual‐function protease inhibitor and neuroactive peptide

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Marine cone snails produce a diverse array of bioactive peptides, known as conotoxins, in their venom. Given their high target potency and specificity, conotoxins are attractive compounds for the development of precision research tools and pharmacological agents.

Studies on Trypanosoma rangeli Tejera 1920. VII - Its effect on the survival of infected triatomine bugs

Memorias do Instituto Oswaldo Cruz, 1984
The pathological effects of Trypanosoma rangeli on Rhodnius prolixus and R. robustus, and the relation of mortality to infection, were studied under laboratory conditions. Frequent observations revealed that when the first instar nymphs of R.

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

PLoS 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.

An atlas of plant selenium metabolism

New Phytologist, Volume 250, Issue 4, Page 2041-2060, May 2026.
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.

Effects of precocene and azadirachtin in Rhodnius prolixus: some data on development and reproduction

Memorias do Instituto Oswaldo Cruz, 1987
The results presented in this paper clearly indicate that precocene and azadirachtin are effective inhibitors of moulting and reproduction in the hemipteran Rhodnius prolixus. The time of application is important and only applications of these substances

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

Entomologia 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 azadirachtin in Rhodnius prolixus: data and hypotheses [PDF]

Memórias do Instituto Oswaldo Cruz, 1991
The effects of azadirachtin A, a tetranortriterpenoid from the neem tree Azadirachta indica J., on both development and interaction between Trypanosoma cruzi, the causative agent of Chagas' disease, and its vector Rhodnius prolixus were studied. Given through a blood meal, a dose-response relationship of azadirachtin was established using antifeedant ...

Bed bug preferences for host odor or aggregation odor are differentially modulated by physiological state in various odorscapes

Pest Management Science, Volume 82, Issue 2, Page 1426-1436, February 2026.
The bed bug olfactory system is highly tuned to two odor sources with dedicated odor information‐processing pathways that are modulated by the satiety–hunger state. Understanding the dynamic nature of switching odor preferences at different phases of blood digestion will contribute to the development of lures with host kairomones and aggregation ...
