Chagas disease, a neglected global health concern primarily transmitted through the bite and feces of kissing bugs, has garnered increasing attention due to recent outbreaks in northern Brazil, highlighting the role of oral transmission facilitated by the kissing bugs species Rhodnius robustus and Rhodnius pictipes. These vectors are associated with palm trees with large crowns, such as the maripa palm (Attalea maripa) and moriche palm (Mauritia flexuosa). In this study, we employ maximum entropy (MaxEnt) ecological niche models to analyze the spatial distribution of these vectors and palm species, predicting current and future climate suitability. Our models indicate broader potential habitats than documented occurrences, with high suitability in northern South America, southern Central America, central Africa, and southeast Asia. Projections suggest increased climate suitability by 2040, followed by a reduction by 2080. This study identifies present and future areas suitable for kissing bugs and palm tree species due to climate change, aiding in the design of prevention and management strategies.

The hemoflagellate parasite is transmitted by triatomine kissing bugs and may co-infect humans together with its Chagas disease-causing congener . Using real-time quantitative polymerase chain reaction (RT-qPCR) and antimicrobial assays, we studied () the temporal and spatial distribution of in common bed bugs, , following oral ingestion and hemocoelic injection of and () the immune responses of bed bugs induced by infections. Irrespective of infection mode, no live were present in the bed bugs' hemolymph, salivary glands, or feces.

Chagas disease, vectored by kissing bugs, poses a public health problem across the Americas. The best way for reducing disease transmission is through vector control, which is currently based on the use of insecticides. However, insecticide resistance, and environmental and health issues, stress the need for new, environmentally-friendly methods for reducing vector-host contacts.

Article Synopsis
- - Kissing bugs are effective blood-feeders, using cues like carbon dioxide and heat to locate their warm-blooded hosts, but recent studies show they may also feed on cold-blooded animals and insects.
- - The bugs utilize various sensory signals, such as temperature changes and odors, for feeding decisions, and are now found to consume plant or fruit fluids, indicating a more diverse diet than previously thought.
- - Future research should explore how kissing bugs sense and react to different sensory inputs from various hosts and plant sources, which could inform strategies for surveillance and control, as well as shed light on their evolutionary transition from predatory to blood-feeding behavior.

is the causative agent of Chagas disease, a zoonotic infectious disease considered a leading cause of cardiomyopathy, disability, and premature death in the Americas. This parasite spends its life between a mammalian host and an arthropod vector, undergoing essential transitions among different developmental forms. How senses microenvironmental changes that trigger cellular responses necessary for parasite survival has remained largely unknown.

Article Synopsis
- Triatomines are blood-sucking insects that spread Chagas disease, so trapping them is essential for reducing human contact and controlling the disease.
- The study tested the attraction of different triatomine species to volatiles from fermented products and commercial lures using double-choice bioassays.
- The results showed that volatiles from lactic fermentation and some fermented fruits effectively attracted triatomines, indicating their potential for disease control, while some products seemed to repel the insects.
