Pollinators play a vital role in ecosystem health as well as being essential to maintaining food security. With significant declines in both managed and wild pollinator populations in recent years scientists and regulators have sought answers to the cause of this decline as well as looking toward implementing steps to ensure pollinator populations now and in the future. Pesticide Risk Assessment for Pollinators focuses on the role pesticides play in impacting bee populations and looks to develop tools to better assess the risks that go hand in hand with their use.
Pesticide Risk Assessment for Pollinators opens with two chapters that provide a sound foundation in the biology of both Apis and non-Apis species of pollinators. Chapters then move to coverage of risk assessment analyses of pesticide use, decision-making processes, and statistical and modeling tools useful in assessing the impacts of pesticide use on pollinator populations.
Summarizing the current state of the science surrounding risk assessment for Apis and non-Apis species, Pesticide Risk Assessment for Pollinators is a timely work that will be of great use to the agricultural and environmental science communities.

"The debate concerning the effects of neonicotinoids on bees, though probably not the one about mobile phones, will no doubt continue for a long time so the publication of this excellent and comprehensive book is timely."
