Insecticide Resistance in Triatomines
2021The control of Chagas disease vectors has been based principally on spraying dwellings with insecticides. This strategy reduced the geographic range and infestation prevalence of major vectors leading to the interruption of disease transmission in several areas from endemic regions.

Sensory Biology of Triatomines
2021Sensory systems mediate behaviors such as food, mate and shelter search, habitat selection, avoidance of environmental risks, escape from predators, and communication with conspecifics. Yet, immersed in an environment full of flowing information, triatomines, as other living organisms, must recognize and make use of adequate and sparse sensory stimuli.

The Immune System of Triatomines
2021All insects rely on an innate immune system to eliminate potentially lethal parasites and pathogens. In kissing bugs, this immune system comprises a plethora of elements that first recognize parasites and pathogens as non-self, followed by a multi-faceted response to eliminate them.

The Pharmacopea within Triatomine Salivary Glands
Trends in Parasitology, 2020Triatomines are blood-feeding insects that prey on vertebrate hosts. Their saliva is largely responsible for their feeding success. The triatomine salivary content has been studied over the past decades, revealing multifunctional bioactive proteins targeting the host´s hemostasis and immune system.

Survival of Arboviruses in Trypanosome-Infected Triatomines
The American Journal of Tropical Medicine and Hygiene, 1977The potential of triatomines to maintain arboviruses was demonstrated by the ability of Rhodinius prolixus with experimentally punctured abdomen to harbor Venezuelan equine encephalitis (VEE) virus for at least 4 months and St. Louis encephalitis virus for 1 month.

Oogenesis and egg development in triatomines: a biochemical approach [PDF]
Anais Da Academia Brasileira De Ciencias, 2005 In triatomines, as well as in other insects, accumulation of yolk is a process in which an extra-ovarian tissue, the fat body, produces yolk proteins that are packed in the egg. The main protein, synthesized by the fat body, which is accumulated inside the oocyte, is vitellogenin. This process is also known as vitellogenesis.

Infecting Triatomines with Trypanosomes
2020The infection of triatomines with trypanosomes can be performed with different forms of the parasite, and the procedure is important not only for vector-parasite interaction studies but also for maintaining the infectivity of parasite strains, which guarantees more realistic biological and molecular investigations.

Triatomine physiology in the context of trypanosome infection
Journal of Insect Physiology, 2017Triatomines are hematophagous insects that feed on the blood of vertebrates from different taxa, but can occasionally also take fluids from invertebrate hosts, including other insects. During the blood ingestion process, these insects can acquire diverse parasites that can later be transmitted to susceptible vertebrates if they complete their ...

Anatomy of the Nervous System of Triatomines
2021The nervous system of triatomines follows the general plan for insects in terms of organization. Yet, its anatomy is in line with the form of the different regions of the bug’s body. The brain is located in the posterior region of the elongated head, the cavity of which is mostly occupied by the cibarial pump.

Blood Digestion in Triatomine Insects
2021Triatomine insects had a fundamental role in the establishment of essential concepts of insect physiology, especially thanks to the use of Rhodnius prolixus as a model for basic research in the last century. The major unique feature that made triatomines excellent models is their strictly hematophagous way of life, as molting in nymph stages and ...
