Thus, these seed treatments are ineffective and cause more harm than good. It would better serve famers and the environment to actively encourage natural predation, rather than rely on toxic chemicals that only perpetuate the dangerous cycle of pesticide use.<\/p>\n<p>Ms. Douglas\u2019 findings add merit to the influx of research regarding neonicotinoids and their impacts on pollinators and other non-target beneficial species. Neonicotinoids are a relatively new class of insecticides that share a common mode of action that affect the central nervous system of insects, resulting in paralysis and death. While the issue of pollinator declines is diverse and complex, with many factors potentially contributing to the cause, pesticides have consistently been implicated as a key factor, not only through immediate bee deaths, but also through sublethal exposure causing changes in bee reproduction, navigation and foraging. Further research has demonstrated that neonicotinoids create increased vulnerability to diseases through exposure, impact a wide range of habitats, and have persistent, long term implications.<\/p>\n<p>Earlier this year, <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/2015\/02\/neonics-harm-bees-brain-cells-according-to-researchers\/\">researchers found<\/a> that chronic exposure to neonicotinoids increases neuronal vulnerability to mitochondrial dysfunction in the bumblebee. Exposed bees will have greater difficulty, for instance, in recognizing the smell of a flower, or how to find their way back to their colony. In June 2015, <a href=\"http:\/\/www.sciencedirect.com\/science\/article\/pii\/S1226861515000813\">researchers demonstrated <\/a>that honey bees exposed to <a href=\"https:\/\/www.beyondpesticides.org\/gateway\/index.php?pname=imidacloprid.php\">imidacloprid<\/a>, a toxic neonic, are more susceptible to heat shock. Researchers have also found that bees can become <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/2015\/04\/research-finds-bees-prefer-foods-treated-with-bee-killing-insecticides\/\">addicted to neonicotinoids<\/a> in the same way that humans can become addicted to cigarettes. Non-target effects of rampant neonicotinoid use include<a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/2014\/07\/bird-population-declines-linked-to-neonicotinoid-pesticides-adding-to-previous-science\/\"> bird population declines<\/a> and <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/2015\/02\/new-research-links-bee-killing-insecticide-to-monarch-butterfly-deaths\/\">monarch butterfly loss<\/a>. \u00a0More research can be found on Beyond Pesticides\u2019 <a href=\"https:\/\/www.beyondpesticides.org\/pollinators\/research.php\"><em>What the Science Shows<\/em><\/a> page, where studies are listed to highlight the impact of pesticides on these organisms.<\/p>\n<p>The implications of the findings described above only strengthen the need for meaningful policy change on the federal level. <em>Saving America\u2019s Pollinators Act<\/em> \u00a0requires the Environmental Protection Agency (EPA) to suspend the registration of all neonicotinoid insecticides that are registered for use in seed treatment, soil application, or foliar treatment on bee attractive plants, trees and cereals until EPA has fully determined that these toxic chemicals do not cause unreasonable adverse effects on pollinators.  \u00a0You can help to protect America\u2019s pollinators by <a href=\"http:\/\/action.beyondpesticides.org\/p\/dia\/action3\/common\/public\/?action_KEY=14785\">submitting a letter<\/a> to your representative, urging them to support <em>Saving America\u2019s Pollinators Act<\/em>.

However, little is being done at the federal level to protect bees and other pollinators from these pesticides.

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.

This resulted in a loss of crop due to a decline in beneficial insect predators and an [&hellip;]","og_url":"https:\/\/beyondpesticides.org\/dailynewsblog\/2015\/07\/neonicotinoids-harm-beneficial-predatory-insects-through-secondary-poisoning\/","og_site_name":"Beyond Pesticides Daily News Blog","article_publisher":"https:\/\/www.facebook.com\/beyondpesticides","article_author":"https:\/\/www.facebook.com\/beyondpesticides\/","article_published_time":"2015-07-23T05:13:57+00:00","article_modified_time":"2015-07-23T14:00:57+00:00","og_image":[{"url":"https:\/\/www.beyondpesticides.org\/dailynewsblog\/wp-content\/uploads\/2015\/07\/Chlaenius-tricolor-300x225.jpg","type":"","width":"","height":""}],"author":"Beyond Pesticides","twitter_card":"summary_large_image","twitter_creator":"@ByondPesticides","twitter_site":"@ByondPesticides","twitter_misc":{"Written by":"Beyond Pesticides","Est. reading time":"4 minutes"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"Article","@id":"https:\/\/beyondpesticides.org\/dailynewsblog\/2015\/07\/neonicotinoids-harm-beneficial-predatory-insects-through-secondary-poisoning\/#article","isPartOf":{"@id":"https:\/\/beyondpesticides.org\/dailynewsblog\/2015\/07\/neonicotinoids-harm-beneficial-predatory-insects-through-secondary-poisoning\/"},"author":{"name":"Beyond Pesticides","@id":"https:\/\/beyondpesticides.org\/dailynewsblog\/#\/schema\/person\/1b5c0a0981b549cc5b628770073031f4"},"headline":"Neonicotinoids Harm Beneficial Predatory Insects through Secondary Poisoning","datePublished":"2015-07-23T05:13:57+00:00","dateModified":"2015-07-23T14:00:57+00:00","mainEntityOfPage":{"@id":"https:\/\/beyondpesticides.org\/dailynewsblog\/2015\/07\/neonicotinoids-harm-beneficial-predatory-insects-through-secondary-poisoning\/"},"wordCount":906,"commentCount":0,"publisher":{"@id":"https:\/\/beyondpesticides.org\/dailynewsblog\/#organization"},"image":{"@id":"https:\/\/beyondpesticides.org\/dailynewsblog\/2015\/07\/neonicotinoids-harm-beneficial-predatory-insects-through-secondary-poisoning\/#primaryimage"},"thumbnailUrl":"https:\/\/www.beyondpesticides.org\/dailynewsblog\/wp-content\/uploads\/2015\/07\/Chlaenius-tricolor-300x225.jpg","articleSection":["Agriculture","Alternatives\/Organics","Announcements","Chemicals","Habitat Protection","Increased Vulnerability to Diseases from Chemical Exposure","neonicotinoids","Persistence","Pollinators","Take Action","Thiamethoxam","Wildlife\/Endangered Sp."],"inLanguage":"en-US","potentialAction":[{"@type":"CommentAction","name":"Comment","target":["https:\/\/beyondpesticides.org\/dailynewsblog\/2015\/07\/neonicotinoids-harm-beneficial-predatory-insects-through-secondary-poisoning\/#respond"]}]},{"@type":"WebPage","@id":"https:\/\/beyondpesticides.org\/dailynewsblog\/2015\/07\/neonicotinoids-harm-beneficial-predatory-insects-through-secondary-poisoning\/","url":"https:\/\/beyondpesticides.org\/dailynewsblog\/2015\/07\/neonicotinoids-harm-beneficial-predatory-insects-through-secondary-poisoning\/","name":"Neonicotinoids Harm Beneficial Predatory Insects through Secondary Poisoning -

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\/16202","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=16202"}],"version-history":[{"count":9,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/16202\/revisions"}],"predecessor-version":[{"id":16215,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/16202\/revisions\/16215"}],"wp:attachment":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/media?parent=16202"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/categories?post=16202"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/tags?post=16202"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
