Allometry, reproductive phenology and temporal dynamics of the synanthropic scorpion Tityus serrulatus (Scorpiones: Buthidae) in Central Brazil

Abstract Tityus serrulatus Lutz & Mello, 1922 (Scorpiones: Buthidae), known in Brazil as the yellow scorpion, is the most medically significant scorpion species in South America. This study investigates the allometry, reproductive phenology and temporal population dynamics of a synanthropic T. serrulatus population in Central Brazil. Over 14 months, 245 individuals were collected and measured. Morphometric analyses revealed distinct resource allocation strategies: juveniles prioritize axial elongation, whereas adults exhibit exponential weight gain probably linked to gonadal development and mesosomal dilation. Furthermore, we confirmed near‐perfect pedipalp isochely. Circular statistical analyses of population dynamics indicated recurrent recruitment across the annual cycle, facilitated by favourable urban microhabitats, with adult abundance peaking during the transition to the wet season, sequentially followed by juvenile demographic pulses. Notably, population resilience following chemical pest control interventions directly challenges traditional management practices. These findings provide a quantitative baseline for understanding the seasonal dynamics and life‐history strategy of T. serrulatus , information that may contribute to optimizing monitoring and management programmes.
