摘要: Abstract Stressors are omnipresent in the environment and trigger specific physiological and/or behavioural responses that remain relatively less known invertebrates. Among parameters used to quantify impact of stress on physiology, circulating level glucose is commonly aquatic crustacean species. Terrestrial isopods small crustaceans as bioindicators soil quality; however, their response environmental stressors remains poorly documented. In laboratory conditions, we investigated how different influence two terrestrial isopod Thus, exposed Armadillidium vulgare Porcellio dilatatus a series both acute (physical) chronic (temperature, social isolation, exposure herbicide) mimic potentially stressful situations encountered environment. Our results revealed that, for species, glycaemia not impacted by thermic shock (1 h at 4 °C), mechanical disturbances (1 min shaking or upside-down motion) isolation (4 weeks) population level. Nevertheless, observed significantly higher sensitivity male P. movements males species isolation. Acute (96 h) (21 days) glyphosate (1.8–2.5 kg.ha−1) did levels A. vulgare. However, tested doses, individuals 25 days subjected an additional stressor (haemolymph sampling 96 h) had comparison control. Survival was also joint application intermediate haemolymph sampling. We conclude good indicator study isopods. Additional studies this parameter, combined with other indicators, needed better characterize response.
