Abstract
The effect of pesticide mixtures and electromagnetic fields were evaluated on honeybees in three experimental sites located in northern Italy: a control site far from anthropogenic stress sources, a semi-natural site close to a high voltage electric line and an agricultural site with intensive pesticide treatments. From each experimental site, young workers and foraging bees were taken monthly from May to October and analysed for four enzymatic biomarkers: acetylcholinesterase (AChE), catalase (CAT), glutathione S-transferase (GST) and alkaline phosphatase (AP). Results revealed timeand site-specific effects in respect to control site, confirming the role of biomarkers as diagnostic and early-warning tools for multi-stress sources on honeybees. In the electromagnetic-stress site an effect of an over-activation of all analyzed biomarkers was observed at the end of the season. According to other literature findings, this event was related to a behavioral over-activation in a period in which bees should prepare themselves to overwintering. This finding poses potential problems to winter survival. In the pesticide-stress site, different pesticide-induced responses were identified. We demonstrated in the field that pesticide mixtures, currently used in agriculture, were able to greatly affect biochemical parameters of bees (with both enzymatic under- and over-activations).
