Of these residues, 13 different compounds were found in bees, 61 in beebread (packed pollen within the hive), and 70 were found in wax. Researchers gauged the effect of pesticide exposure not only by looking at the number of pesticides in colonies, but also their toxicological relevance over a specific threshold, as well as through the calculation of a hazard quotient (HQ), which evaluates \u00a0the cumulative toxicity of various pesticide residues. Pesticide detections and HQ spiked when colonies were placed in agricultural fields for pollination (including blueberry, apple, citrus and cucumber production), and decreased when placed in a holding yard or put into honey production.<\/p>\n<p>During the pollination season, colonies that died-off had higher total pesticide residues in their wax over the course of sampling than colonies that survived. While researchers found that insecticides were the greatest contributor of increased hazard to honey bee colonies, elevated levels of fungicides appeared to be correlated with colonies that died within ~30 days after sampling.  \u00a0&#8220;We were surprised to find such an abundance of fungicides inside the hives, but it was even more surprising to find that fungicides are linked to imminent colony mortality,&#8221; said Kirsten Traynor, PhD, a postdoctoral researcher in entomology at UMD and lead author on the study. &#8220;These compounds have long been thought to be safe for bees. We&#8217;re seeing them at higher doses than the chemicals beekeepers apply directly to the colonies to control varroa mites. So that is particularly concerning.&#8221;<\/p>\n<p>Pesticide load and hazard were also elevated in colonies that experienced a queen event \u2014when a queen is replaced, in the process of being replaced, or queenless. A queen event is a predictor that a colony will die-off within ~50 days. Researchers found levels of synthetic pyrethroids were higher in colonies with a queen event, <a href=\"http:\/\/beyondpesticides.org\/dailynewsblog\/2010\/03\/pyrethroids-found-to-impair-bee-reproduction\/\">echoing past research<\/a> showing adverse effects to bee reproduction from pyrethroid exposure. While scientists did not find a significant contribution from <a href=\"https:\/\/www.beyondpesticides.org\/programs\/bee-protective-pollinators-and-pesticides\/chemicals-implicated\">neonicotinoids, a class of chemicals widely implicated <\/a>in bee and other pollinator declines, co-authors of the research note the study may not have been set up to adequately investigate their impact.<\/p>\n<p>\u201cWe just did not find neonicotinoids in the colonies,\u201d said Dennis vanEngelsdorp, PhD, UMD professor and co-author of the study. \u201cThere were some trace residues of neonicotinoids in a few samples, but not nearly on par with other compounds. However, it\u2019s possible we did not test the right matrix\u201d\u201dwe did not test nectar, for example\u201d\u201dor that the product breaks down faster than others in the collection process or that neonicotinoids are simply not very prevalent when crops are flowering.\u201d Environmental and beekeeper groups have criticized Dr. vanEnglesdorp in the past for pinning the worldwide decline of honey bees on the varroa mite, and downplaying the role that neonicotinoid pesticides play in pollinator die-offs.<\/p>\n<p>The implications of this research stretch beyond a single class of chemicals. While the <a href=\"http:\/\/beyondpesticides.org\/programs\/bee-protective-pollinators-and-pesticides\/what-the-science-shows\">body of science<\/a> on neonicotinoids, including <a href=\"http:\/\/beyondpesticides.org\/dailynewsblog\/2016\/01\/epa-data-confirms-honey-bee-exposure-to-hazardous-pesticides\/\">EPA\u2019s own determination that these chemicals are highly toxic to bees<\/a>, indicates that they should be immediately removed from use, it is evident that chemcial-intensive \u00a0agriculture in general is owed much of the blame. Rather than focus on reducing pesticide exposure or refraining from use when bees are present, agrichemical companies, the conventional farming community, and federal regulators must take a long look at what practices are truly sustainable in the long term. It is clear that insect pollination and its subsequent health and economic benefits will not be maintained if measures aren\u2019t taken to drastically shift agricultural production toward safer practices modeled on organic agriculture. By focusing on soil health, biodiversity, cultural practices like crop rotation and intercropping, and limited off-farm inputs, organic systems represent a <a href=\"http:\/\/beyondpesticides.org\/dailynewsblog\/2016\/02\/organic-agriculture-essential-to-a-sustainable-future\/\">viable, scalable path forward<\/a>.<\/p>\n<p>Concerned residents can help <a href=\"http:\/\/beyondpesticides.org\/programs\/lawns-and-landscapes\/tools-for-change\">facilitate the shift to organic practices right in their own community<\/a> by encouraging their local leaders to transition from conventional to organic landscaping. Individuals in farming communities can start conversations about safer practices directly with their neighbors and at community meetings. Consumers can help promote the growth of organic agriculture by purchasing organic products whenever possible.

The founders, who established Beyond Pesticides (originally as National Coalition Against the Misuse of Pesticides) as a nonprofit membership organization in 1981, felt that without the existence of such an organized, national network, local, state and national pesticide policy would become, under chemical industry pressure, increasingly unresponsive to public health and environmental concerns. Beyond Pesticides believes that people must have a voice in decisions that affect them directly. We believe decisions should not be made for us by chemical companies or by decision-makers who either do not have all of the facts or refuse to consider them. Learn more about our work, read A Year in Review\u20142021, our accomplishments are your victories! Beyond Pesticides seeks to protect healthy air, water, land, and food for ourselves and future generations. By forging ties with governments, nonprofits, and people who rely on these natural resources, we reduce the need for unnecessary pesticide use and protect public health and the environment. Beyond Pesticides provides hands-on services to the public and supports local action by: identifying and interpreting hazards; and, designing safe pest management programs. With the information provided by Beyond Pesticides, people may not only be able to make informed choices and adopt practices that protect themselves and their families from unnecessary exposure to pesticides, but they will be able to effect changes on community-wide pest management decisions and policies that govern pesticide use, such as pesticide uses in parks, schools, for community insect control and along roadsides.

The founders, who established Beyond Pesticides (originally as National Coalition Against the Misuse of Pesticides) as a nonprofit membership organization in 1981, felt that without the existence of such an organized, national network, local, state and national pesticide policy would become, under chemical industry pressure, increasingly unresponsive to public health and environmental concerns. Beyond Pesticides believes that people must have a voice in decisions that affect them directly. We believe decisions should not be made for us by chemical companies or by decision-makers who either do not have all of the facts or refuse to consider them. Learn more about our work, read A Year in Review\u20142021, our accomplishments are your victories! Beyond Pesticides seeks to protect healthy air, water, land, and food for ourselves and future generations. By forging ties with governments, nonprofits, and people who rely on these natural resources, we reduce the need for unnecessary pesticide use and protect public health and the environment. Beyond Pesticides provides hands-on services to the public and supports local action by: identifying and interpreting hazards; and, designing safe pest management programs. With the information provided by Beyond Pesticides, people may not only be able to make informed choices and adopt practices that protect themselves and their families from unnecessary exposure to pesticides, but they will be able to effect changes on community-wide pest management decisions and policies that govern pesticide use, such as pesticide uses in parks, schools, for community insect control and along roadsides. Beyond Pesticides believes that people must have a voice in decisions which affect them directly.","sameAs":["https:\/\/www.beyondpesticides.org","https:\/\/www.facebook.com\/beyondpesticides\/","https:\/\/www.instagram.com\/beyondpesticides\/","https:\/\/www.linkedin.com\/company\/beyond-pesticides\/","https:\/\/x.com\/ByondPesticides","https:\/\/www.youtube.com\/user\/bpncamp\/"],"url":"https:\/\/beyondpesticides.org\/dailynewsblog\/author\/beyond-pesticides\/"}]}},"_links":{"self":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/19046","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/comments?post=19046"}],"version-history":[{"count":18,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/19046\/revisions"}],"predecessor-version":[{"id":19067,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/19046\/revisions\/19067"}],"wp:attachment":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/media?parent=19046"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/categories?post=19046"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/tags?post=19046"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
