Summary: The study evaluated the insecticidal effect of fluralaner on Triatoma brasiliensis after feeding on treated dogs, showing 100% mortality within 7 months post-treatment, declining to 0% after 12 months. This indicates a potential long-term approach to control vector transmission of Chagas disease, especially in endemic areas.

Summary: Insecticide resistance is a severe global problem for vector control. A recent study analysed the molecular metabolite changes in deltamethrin-resistant An. sinensis mosquitoes using liquid chromatography tandem mass spectrometry (LC-MS/MS) and found that the differential metabolites were mainly associated with glycerophospholipid metabolism. These findings provide further mechanistic understanding of insecticide resistance in An. sinensis.

Summary: Insecticide resistance in Triatoma infestans was detected in Argentina, and this study focused on determining the morphometric changes in wings, heads, and antennae of resistant individuals compared to susceptible ones. The results indicate that resistant insects have smaller wings and heads, which may affect their dispersal potential and behavioral patterns. Additionally, sensory simplification was observed in resistant individuals, especially in females.

Summary: This study revealed that miR-4448 is involved in deltamethrin resistance in mosquitoes by targeting CYP4H31, leading to decreased expression of CYP4H31. These findings contribute to a better understanding of the mechanisms underlying deltamethrin resistance.

Summary: This study found high-intensity resistance to pyrethroids in southern Benin, but pre-exposure to PBO significantly increased susceptibility to these insecticides in different An. gambiae s.l. populations. The kdr resistance allele (1014F) frequency was high in all study sites, while the ace-1 resistance allele (G119S) frequency was low. The use of PBO insecticide-treated bed nets may help maintain control of An. gambiae (s.l.) in southern Benin.

Summary: Autogeny, the capability of developing eggs without feeding, has been observed in some groups of arthropods. In this study, the relationship between nutritional status and egg development in Triatominae was investigated. The results showed that the ability to develop eggs is a continuous function determined by molting weight and blood intake, rather than a simple switch on-off phenomenon. This autogenic ability allows Triatominae to accelerate population growth under favorable or low competition conditions.

Summary: Transcriptomic analysis of An. coluzzii legs revealed enrichment of genes involved in chemical stimuli detection and ABC transporters, with resistant populations showing overexpression of detoxification enzymes and cuticular proteins. Short-term exposure to pyrethroids induced upregulation of genes encoding for GPCRs, transporters, odorant-binding proteins and salivary gland proteins.

Summary: This study provides a comprehensive description and identification of key species within the Triatoma genus through morphological and morphometric analysis, offering new features for species differentiation. By studying the female external genitalia and eggshells, the four species T. garciabesi, T. guasayana, T. patagonica, and T. sordida can be successfully distinguished.

Summary: The study identified CYP4PR1 as predominantly expressed in the integument tissue of T. infestans and not induced by deltamethrin. Knockdown of CYP4PR1 in pyrethroid-resistant nymphs significantly increased insect mortality after deltamethrin application, indicating its potential role in metabolic resistance. These results suggest that the integument plays a crucial role in metabolic resistance and that CYP4PR1 may contribute to resistance in integument tissue of T. infestans.

Summary: The Rhodniini tribe, originating around 17.91 million years ago, includes various species with distinct bioclimatic niches. The oldest species, Rhodnius domesticus, dates back to approximately 9.13 million years. Most species exhibit clear allopatric distribution and colonization of specific trees and bird nests plays a key role in the speciation of these taxa.

Summary: The control of Chagas disease in endemic countries heavily relies on insecticide spraying to eliminate triatomine vectors. Resistance to pyrethroids, the preferred insecticide, poses a significant obstacle to effective control. The study evaluated the role of three Rhodnius prolixus CYP4EM subfamily genes in blood meal digestion and after exposure to deltamethrin, revealing potential targets for enhancing vector control strategies.

Summary: The study evaluated the occurrence, natural infection, and spatial distribution of triatomines in the urban area of Montes Claros, a municipality endemic to Chagas disease in the north of Minas Gerais, Brazil. The Chagas disease control program in this area is disjointed, and the diversity of infected triatomines in residential units raises concerns about potential transmission risks to domestic animals and humans.
