Pesticides are believed to be a major contributor to regional pollinator declines which hassled to pollination insecurity. This dissertation furthers the evolving process of integrating pollinator health into the Eastern US apple orchard IPM program that has been termed IPPM. It focuses on the pesticide risk assessment for orchard pollinators by measuring species-based differences in toxicity responses of wild bees and honey bees to pesticide exposure through ingestion by measuring delayed mortality and sublethal developmental effects on adults and larvae. We also compare pesticide regulations between the US and the EU that shows the pros and cons in present pesticide regulatory decisions of these countries, and suggest future directions in instructing new policies regarding pollinator health. Previously in this lab, pesticide residue levels in apple pollen and nectar were measured to quantify the ingestion exposure of adult and larval bees to commonly used orchard pesticides. In this study, we developed a new ingestion bioassay protocol for assessing pesticide toxicity to the larvae and adults of a solitary bee (Megachilidae: Osmia cornifrons) to compare its toxicity profile to the European honey bee. Results from several bioassays allowed us to evaluate the effectiveness of present IPPM pesticide recommendations and have already informed our decision to modify the timing and selection of several insecticide and fungicide pest control tactics to increase the safety to both managed and wild pollinators regionally. This information will also influence pesticide registration decisions and pesticide regulatory frameworks for pollinator protection in the future.

Pollinators play a vital role in ecosystem health and are essential to ensuring food security. With declines in both managed and wild pollinator populations in recent years, scientists and regulators have sought answers to this problem and have explored implementing steps to protect pollinator populations now and for the future. Pesticide Risk Assessment for Pollinators focuses on the role pesticides play in impacting bee populations and looks to develop a risk assessment process, along with the data to inform that process, to better assess the potential risks that can accompany the use of pesticide products. Pesticide Risk Assessment for Pollinators opens with two chapters that provide a biological background of both Apis and non-Apis species of pollinators. Chapters then present an overview of the general regulatory risk assessment process and decision-making processes. The book then discusses the core elements of a risk assessment, including exposure estimation, laboratory testing, and field testing. The book concludes with chapters on statistical and modeling tools, and proposed additional research that may be useful in developing the ability to assess 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 environmental science and agricultural research communities. Assesses pesticide risk to native and managed pollinators Summarizes the state of the science in toxicity testing and risk assessment Provides valuable biological overviews of both Apis and non-Apis pollinators Develops a plausible overall risk assessment framework for regulatory decision making Looks towards a globally harmonized approach for pollinator toxicity and risk assessment

"In May 2009, the Government of Canada, through the Pest Management Regulatory Agency (PMRA) of Health Canada, asked the Council of Canadian Academies to appoint an expert panel to answer the question, "What is the scientific status of the use of integrated testing strategies in the human and environmental regulatory risk assessment of pesticides?" The charge to the Panel was further specified in a series of sub-questions: [1] What is the state of the science of the tools and data sources associated with integrated testing strategies? [2] What is the current status of the use of integrated testing strategies for the risk assessment of pesticides, pharmaceuticals, industrial chemicals, and other chemical substances by regulatory agencies around the world? [3] Could there be potential impacts on the public's perception and confidence in regulatory risk assessment and risk management decisions for pesticides if integrated testing strategies were implemented?"--P. xiii-xiv.
