Monitoring of neonicotinoid pesticides in beekeeping

Abstract

The decline of pollinating species is correlated to the extensive use of neonicotinoids against pest insects for crop protection. In this study, the concentrations of neonicotinoid insecticides were determined in honeybees, honeycomb and honey samples, collected in Spring 2015 (blooming period) from different areas in Sicily (IT), to carry out an evaluation of bees products' safety and an overview of neonicotinoid contamination in beekeeping. The results obtained showed only the presence of clothianidin in bee samples and these concentrations don't represent a risk for bees' vitality and safety. The absence of residue in all honey samples, instead, showed the quality of bee products.
