Effects of the alarm pheromone on Triatoma pallidipennis behaviour

Physiological Entomology, Volume 50, Issue 4, Page 374-387, December 2025.
T. pallidipennis performs behavioural acts in response to volatiles emitted by mechanically disturbed conspecifics. T. pallidipennis shows a repellent response when exposed to volatiles emitted by mechanically disturbed conspecifics. Isobutyric and propanoic acids can be used as repellents of T. pallidipennis. Abstract Adults of some Triatomine species,

Comparison of hemocytes of 5th-instar nymphs of Rhodnius prolixus (Stal) and Rhodnius robustus (Larousse 1927), before and after molting

Revista de la Facultad de Medicina, 2015
Background. The immune response of insects involves humoral factors and cellular elements known as hemocytes. There are different reports that explore the response of hemocytes to infections, but the effect that molting has on this response has not been

Research needs for Chagas disease prevention.

, 2010
We present an overview of the two main strategies for the primary (vector control) and secondary (patient care) prevention of Chagas disease (CD). We identify major advances, knowledge gaps, and key research needs in both areas.

Source of Moulting Hormone in Rhodnius [PDF]

Nature, 1951
THE immediate source of the hormone which induces moulting in the larvae and pupae of Lepidoptera is the prothoracic gland1. But this gland is itself activated by a secretion from neuro-secretory cells in the dorsum of the brain2. It has seemed probable for some time that a similar two-stage control of moulting might exist in other insects3; and ...

Characterization of Triacylglycerol Dynamics and Lipid Metabolism in the Beetle Tribolium castaneum

Archives of Insect Biochemistry and Physiology, Volume 120, Issue 3, November 2025.
Tribolium castaneum larvae accumulate triacylglycerol (TAG) during development, while adults rapidly deplete reserves post‐emergence. Under starvation, beetles prioritize protein catabolism over lipid mobilization, despite increased expression of lipolysis genes, revealing stage‐specific metabolic adaptations in this model insect.

Symbiont-mediated RNA interference in insects [PDF]

, 2016
RNA interference (RNAi) methods for insects are often limited by problems with double-stranded (ds) RNA delivery, which restricts reverse genetics studies and the development of RNAi-based biocides. We therefore delegated to insect symbiotic bacteria the

Evaluation of two candidate molecules—TCTP and cecropin—on the establishment of Trypanosoma brucei gambiense into the gut of Glossina palpalis gambiensis

Insect Science, Volume 32, Issue 5, Page 1747-1760, October 2025.
This study investigates the potential of enhancing the resistance of Glossina palpalis gambiensis to Trypanosoma brucei gambiense to mitigate the transmission of Human African Trypanosomiasis. We successfully cloned genes encoding proteins of interest in Sodalis strains, resulting in recombinant Sodalis (recSodalis) that were micro‐injected into the L3

Everybody loves sugar:first report of plant feeding in triatomines [PDF]

, 2016
Background Triatomines, which are the vectors of Trypanosoma cruzi, have been considered to be exclusive blood feeders for more than 100 years, since the discovery of Chagas disease.
