13Field Study of Pesticide Exposure During Apple Pollination WHC
14Conclusions from Apple Pollination and Migratory Studies 2007-2012 We have developed a good field testing protocol for measuring sub-lethal impacts of pesticides on bee colonies during a single generation reared on contaminated pollen.We have a new population dynamics model of colony development that can be used to predict potential consequences of pesticides in diets and help design future experiments.Bees collect pesticide residue while pollenating apples that reflects orchard sprays, but also contains added pesticides from outside the orchard- Landscape RulesTotal pesticide load in pollen varies widely from colony to colony and from one grower orchard to another- Polylectic Nature Rules
15Conclusions from Apple Pollination and Migratory Studies 2007-2012 Nurse bees from larvae reared on pollen from a single apple pollination event have longevity reduced by ca. 50% and hypertrophied hypopharyngeal glands with unknown colony impactsColonies fed Migratory beekeeper levels of pesticides, herbicides and fungicides show multiple sub-lethal impacts using methods of finer precision than typically used to manage bee coloniesSimulation modeling of colony population dynamics with pesticide feeding indicates that sub-lethal impacts on social dynamics may be more important than lethality for multiple year impacts
26Multi- residue Pesticide Analysis on US Beehive Samples Up to 39 different pesticides per sample, 6+ averageOnly 7% of over 1100 samples incl. controls lacked detectionsFound 131 different pesticides and metabolites18 organophosphates, 16 pyrethroids, 8 carbamates, 7 neonicotinoids,7 chlorinated cyclodienes, 5 organochlorines, 4 insect growth regulators,31 fungicides, 17 herbicides, 3 synergists, 2 formamidines, 13 misc.51 of these are systemic or partially systemic pesticidesOnly 35% of the total pesticides analyzed for were not found.Frazier, M. et al Amer.

28“Our Stolen Future” More Important than “Silent Spring” Endocrine Disruption byPesticides in VertebratesKnown since 1990”sSub-lethal effects ofPesticides binding tohormone receptors atthe wrong time for normalfunctioning yields abnormalConsequences at VERY LOWDOSESWe are just beginning toMeasure these in Bees-But should not be surprisedthey occur
30Summary 1: Pesticides in the (bee) Landscape Pesticide residues are largely unknown for most terrestrial environments relative to ag, urban, forestry use (CA ***)Pesticide residues in water systems in ag areas where measured have significant frequencies above toxic thresholdsand mixtures are the normMany unknowns in quantifying pesticide exposure by bees of all types, thus all studies are relevant until proven otherwiseLab Studies measure the intrinsic action of a chemical on the biological system under controlled conditions thus all results are importantAquatic studies of pesticide mixtures far exceeds terrestrial level studies and offers model approaches on many levels, thus current EPA pesticide program refusal to deal with mixtures has no factual basis
31Overall samples 33% toxic to amphipod: 12% to Midge 98 samples evaluated : trace elements,PAH, PBC, OC’sOverall samples 33% toxic to amphipod: 12% to MidgeBifenthrin (PYR) exceeded threshold in 14% of samplesMean probable effect concentration quotients (PECQs)for groups of compounds improved toxic classificationover that of single compounds
32WARP-MP models use Atrazine model + adjustment factor for each pesticide- further refinements needed112 Pesticides modeled nationwide; 25% of these gavegreater than 50% probability of exceeding 1 or more speciestoxic thresholds in 1 or more streamsMany streams in corn belt had 1 or more pesticides exceedingaquatic life benchmarks indicating vulnerability in this area
33How well are we doing in the Environment? Bees as Environmental Indicators tell us pesticide mixtures are prevalent in pollen and thus in plants of all typesNo pesticide or formulation or industrial chemical monitoring in terrestrial environment only CA has recordsAreas of intensive ag production have highest environmental loads and highest human health consequences- and highest bee colony impactsEPA goal of preventing “undue risks” or societal goals of preventing a degraded environment have not been metDisruption of the biological complexities of environment, ag ecosystems systems largely unknown
34What’s Important about our Food System? We want abundant, uncontaminated, nutritious and affordable food supply of a wide varietyProduction system that is sustainable and in harmony with multiple types of environmentsProduction system that preserves biological diversity, soil productivity, water purityProducers entrusted with major environmental conservation, so should be recognized and supportedProducers with rewarding and sustainable lifestyles
35How well are we doing?Industrial Revolution Paradigm since early 1900’sEconomy of scale for production of “widgets” cost focusedAg Research focused on increased farm productivityFence row to fence row farming + chemicals to manage risk – Landscape and watersheds ignoredReal costs to Environment largely IgnoredEnvironmental Conservation Roles and Farmer Lifestyles largely Ignored as a Major Societal Value
36How Do We Know How Well We are we doing? Shift of small Family Farms to Larger Farms to Factory FarmsEconomy of scale leads to decreased quality and increased environmental costs both of which are largely ignoredWhen environmental impacts of waste disposal extend beyond the borders of the farm, it is a “community safety issue” not a “right to farm” issue (current policies flawed in PA)Corporate farms relegate farmers to surf statusWhile grains may be justified as commodities, the majority of our food does not fit the same model of productionChemically Free Nutritious Food is not a Specialty Item !
38Alternative Model for Food Production Organic Ag- Minimize Chemical Usage through IPMMajor focus on healthy soil = healthy plantsLocally grown and locally consumed ( vs miles)High priority of sustainability of environment and of those engaged in food productionHigh personal innovation in increasing efficiency of productionRecent study confirms less than 10% decrease in production vs. conventional ag ( Kremen Group)
39How well is this alternative model is working? Consumers have been voting approval with their purchases at 20% increase /year for over 20 yearsFastest Growing Sector of most food marketsFarmer’s Markets Reappearing across the USOrganic/Sustainable Farms Growing Rapidly in the East - PASAPreferred quality of food, environmental impacts and lifestyles producedHigh innovation in new approaches: pasture dairy, grass fed beef, high tunnel season extension, pick your own, farm toursVT and PA only states with Raw Milk Marketing
40IPM: a Proven Method with Minimal Chemical Inputs Cotton Production “ Poison Them Bugs”Precise sampling- spray only when neededReduced sprays from to 15 or lessSimulation modeling of crop plants and pest dynamicsBoll Weevil Eradication ProgramRevolutionized cotton production/pesticide reductionResistance Management to Break Treadmill Approach
412015: GMO Plants with Seed Treatments 96 % Seed Treatment goes into environment for potential non-target impactsSystemic pesticide single MOA available all season leads to maximal rate of resistance development in target pestGlyphosate continual use leads to maximal resistance development in all major weed speciesSwitch to another herbicide only fulfills the chemical treadmill approach proven wrong by IPMExtent of Environmental costs currently unknownDoubled glyphosate sales in last 10 years- who has benefited and who is paying?
42How Do We Know How Well are We Doing in Our Food System? 1970 when DDT was banned it was found in fatty tissue and mothers milk throughout US population2014 Survey of 1600 publications on glyphosate concludes that “ most biologically disruptive chemical in our environment”Failure to monitor environment for chemicals does not mean they are absent and exerting no impactsHow can anyone claim to have rational chemical regulation and safety if no one knows what is out there?Unacceptable Situation
43What’s Important in the Politics of Pesticide Public Policy? Public policy that prevents undue risk to people and the environment from chemical usagePublic policy that monitors and reacts aggressively to infractions of specified use and unintended impactsConflicting values of those making and using pesticides balanced with those impacted by themA sustainable system that manages risks according to the best interests of society
44The Iron Triangle of“Power in Washington The “functional way” that things get done yields “favoritism”
45How well we are doing in Pesticide Regulation? 25 Year employee reveals history ofcompromised regulatory decisionsfavoring Chemical IndustriesPolitical influences outweigh scientificrealities in many EPA decisions2014 Boone et al. EPA decisions onAtrazine counter to 3 sets of science advisorsconfirms above history70% Pesticides Registered as “Conditional”Incident Reporting by States Broken butno action to fix it in last 6 yearsEntire Registration Risk Assessment notopen to scientific or public scrutiny

47Pesticides and Public Policy Impacting Bee Health Kellogg Fellow at National Center for Food & Ag Policy- D.C. for 6 weeksHow does the food system policy system work?Overwhelming lack of science in most of the discussion and thinking- its all about the $$Most people involved are not trained in science
48How to Impact Public Policy The larger the voter base, the louder the voiceMake an economically justified caseCoalitions around common goals have become the norm for Ag & Environmental issuesEffectively lobby the process or sue individual entities to force decisionsPartnering with organizations that have experience and connections in D C makes good senseGarnering public support for one’s agenda is a huge undertaking ( but doable e.g. MADD!!)
49What is the Case for the Bee Crisis? Bees the 3rd most important animal in US AgPollination an essential component of US Ag $20 B5.6 M colonies lost since 2006 = $1.12 Billion cost to beekeepers – UNACCEPTABLE SITUATIONLoss of 200 colonies - 5 crops not pollinated = $4.8 M loss of food production to growersResources to replace 30% annual losses depletedWill pollination needs exceed supply in 2015?
50How Do We Know How Well We are Doing? Pesticide regulatory actions in critical need of revisionPolitical influences currently favoring those with the most money and thus the loudest “voices”NHBAB has made very significant advancements in getting seats at the right tables to be heardCoalitions with others who support Conservation and clean Environments are a necessityRegardless of the Iron Triangle in D CPublic Outcry can CHANGE EVERYTHING
