This study investigated the exposure effects of sulfoxaflor, a next-generation sulfoximine insecticide, on the viability, locomotor behavior, and nest-mate interactions of the pavement ant (). Adult worker ants were exposed to 0, 1, 5, 12.5, 25, or 50 mg/L of sulfoxaflor via oral ingestion for 48 h. This short-term exposure to concentrations as low as 1 mg/L had wide ranging effects on multiple locomotive parameters (average speed, mobile average speed, total travel distance), nest-mate interactions (aggression and antennation), and body morphology (abdominal curving). Exposure to sulfoxaflor for 24 h manifested in decreased locomotion, altered intraspecific interactions and the development of abdominal curvature in the 25 and 50 mg/L treatments. Such alterations in mobility and conspecific behavioral parameters would clearly impact the ability of exposed individuals to successfully satisfy resource demands and presents a risk to colony survival.
本研究调查了新一代磺胺亚胺杀虫剂氟啶虫胺腈对铺道蚁的活力、运动行为和巢伴相互作用的暴露影响。成年工蚁通过口服摄入0、1、5、12.5、25或50毫克/升的氟啶虫胺腈，持续48小时。短期暴露于低至1毫克/升的浓度对多个运动参数（平均速度、移动平均速度、总行进距离）、巢伴相互作用（攻击和触角接触）以及身体形态（腹部弯曲）产生了广泛影响。在25和50毫克/升处理中，暴露于氟啶虫胺腈24小时表现为运动减少、种内相互作用改变以及腹部弯曲的发展。移动性和同种行为参数的这种改变显然会影响暴露个体成功满足资源需求的能力，并对蚁群生存构成风险。
