Urban warming and artificial light alter dormancy in the flesh fly

Seasonal changes in temperature and day length are distinct between rural urban areas due to warming the presence of artificial light at night. Many studies have focused on impacts these ubiquitous signatures daily biological events, but empirical their insect seasonality limited. In present study, we used flesh fly Sarcophaga similis as a model determine urbanization incidence timing diapause (dormancy), not only laboratory also conditions. laboratory, entry was affected by night-time levels low 0.01 lux. We placed cages outdoor shelves entry; it retarded approximately four weeks relative that areas. Moreover, almost all flies site facing an residential area failed enter diapause, even late autumn. Although autumnal would mitigate negative effect night, strong pollution seriously disrupts seasonal adaptation.
