Abstract

Hematophagous arthropods rely on taste mechanisms to navigate host selection, feeding, mating, and oviposition. These behaviors are driven by environmental taste cues, which shape acceptance or aversion depending on their valence. Positive stimuli, like low concentrations of salts, sugars, amino acids, and nucleotides, promote feeding and oviposition, while negative stimuli, including high salt, bitter compounds, and nociceptive chemicals, trigger avoidance to prevent hazards. Species-specific adaptations enable blood feeders to overcome ecological challenges. Understanding their behavioral, neuronal, and molecular taste mechanisms aids in developing targeted vector control strategies, such as repellents, toxic baits, and oviposition deterrents, to disrupt disease transmission.

期刊介绍： Current Opinion in Insect Science is a new systematic review journal that aims to provide specialists with a unique and educational platform to keep up–to–date with the expanding volume of information published in the field of Insect Science. As this is such a broad discipline, we have determined themed sections each of which is reviewed once a year. The following 11 areas are covered by Current Opinion in Insect Science. -Ecology -Insect genomics -Global Change Biology -Molecular Physiology (Including Immunity) -Pests and Resistance -Parasites, Parasitoids and Biological Control -Behavioural Ecology -Development and Regulation -Social Insects -Neuroscience -Vectors and Medical and Veterinary Entomology There is also a section that changes every year to reflect hot topics in the field. Section Editors, who are major authorities in their area, are appointed by the Editors of the journal. They divide their section into a number of topics, ensuring that the field is comprehensively covered and that all issues of current importance are emphasized. Section Editors commission articles from leading scientists on each topic that they have selected and the commissioned authors write short review articles in which they present recent developments in their subject, emphasizing the aspects that, in their opinion, are most important. In addition, they provide short annotations to the papers that they consider to be most interesting from all those published in their topic over the previous year.
