Sensing of Volatile Organic Compounds by Haller's Structure in Ixodidae Tick: Electroscutumography and Olfactometric Bioassay.

ABSTRACT: Background: Chemosensation in ticks opens a novel and unique field for scientific research. This study highlights ticks' chemosensory system to comprehend its host-searching behavior and other integrated chemistry and biology involving Haller's structure. Methodology: This study combines microanatomical, electrophysiological, and behavioral experiments to investigate the role of Haller's organ in adult ticks in response to different classes of organic compounds. Results: We showed the microscopic anatomy of Haller's organ in Haemaphysalis darjeeling, present at the terminal segment of the first pair of appendages. Haller's structure serves a vital function in perceiving odor. The electrophysiological activity of adult ticks to different classes of organic compou
