Researchers Delve into Role of Gut Bacteria in Insect Resistance to Pesticides

(Beyond Pesticides, May 9, 2018) An insect’s gut microbiome plays an important role in conferring pesticide resistance, according to a new review published in the Annals of the Entomological Society of America. “Whether you’re looking at agricultural pests, household pests like cockroaches, or medical pests like disease-carrying mosquitoes, insects are great at adapting to whatever we throw at them, especially when it comes to different chemicals,” said lead author Jose Pietri, Ph.D to Entomology Today. The review adds to the numerous ways pests can evade the effects of chemical agriculture, reinforcing calls from recent studies showing that the best method of addressing this issue is to simply stop using synthetic pesticides and employ alternative pest management practices. The authors identify two overarching methods through which microbes help confer resistance to toxic pesticides. The first involves the pest accepting a physiological trade-off, where a pest is able to better withstand an insecticide at the cost of losing its ability to regulate certain gut bacterium. For instance, diamondback moths resistant to fipronil and chlorpyrifos are found to contain higher levels of Lactobacillales, Pseudomonadales, and Xanthomonadales bacteria than non-resistant moths. While this trade-off affects the fitness of the organism, alterations of the bacterial […]

It is an honor to work with you, the members and network of Beyond Pesticides

Thank you for your support and collaboration. Onward in 2018! (Beyond Pesticides, December 22, 2017)  We deeply appreciate your donation to our program in 2017 and it is easy to donate HERE. Year in Review At Beyond Pesticides, we collaborate with organizations and advocate across the country to get our message out on the threat that pesticides pose to human health and the environment. We support local action to stop this threat. And, we assist communities nationwide with the adoption of organic management practices that are more effective and protective than chemical-intensive practices. The partnerships that have been established are, at a more rapid pace, resulting in the adoption of land management practices that are supported by Beyond Pesticides’ strategic vision for a world free of toxic pesticides. Information for Action Beyond Pesticides expanded its role in the forefront of pesticide and organic advocacy with our Action of Week  and Q&A of the Week, in addition to our Daily News, which identifies and delves into key science, policy, and actions that inform local action. The Summer issue of our journal, Pesticides and You, highlighted David Montgomery’s talk at Beyond Pesticides’ National Forum on the importance of soil microbiota and gut microbiome to healthy ecosystems […]

Farmers’ Greater Risk of Diabetes Linked to Pesticide Exposure

(Beyond Pesticides, September, 2017) A recently released report, Gallup-Sharecare State of Well-Being: The Face of Diabetes in the United States, looks at high diabetes rates across various U.S. demographic groups, including those in farming. People working in the transportation sector registered the highest incidence of diagnosed diabetes at 10.6%. But those working as farmers and fishermen came in second, with 8.5% reporting a diagnosis of the disease. Based on a self-reporting survey, The Face of Diabetes in the United States did not differentiate between Type 1 diabetes (which typically manifests in childhood or young adulthood) and Type 2 diabetes (which commonly emerges in adulthood). It did, however, consider lifestyle risk factors that can influence development of each form of the disease. The “farmer and fisher” folks placed more-or-less in the mid-range among all occupations vis-à-vis several of the lifestyle factors that can impact development of the disease (smoking, diet, and obesity), and a bit higher in alcohol consumption, but in fact, reported more exercise than any other category of worker. These data points would seem to suggest that farmers would be at less risk than those in some other occupational categories. For instance, those working in “installation and repair” reported […]

Beyond Pesticides Journal Articles Link Pesticides to Soil Microbiota and Gut Microbiome Poisoning and Resulting Diseases

(Beyond Pesticides, August 15, 2017) With increasing scientific understanding about the importance of beneficial bacteria in soil and the human body —microbiota in the soil and microbiome in the human gut, the summer 2017 issue of Beyond Pesticides’ journal, Pesticides and You, publishes two critical articles to advance the importance of community discussion and action on organic and sustainable practices. The lead article, Sustaining Life: From Soil Microbiota to Gut Microbiome by professor of geomorphology (University of Washington) and author David Montgomery, PhD, contains excerpts from Dr. Montgomery’s talk to Beyond Pesticides’ 35th National Pesticide Forum, documenting the importance of soil microbiota to healthy soil, resilient plants, and sustainability. His piece explains the essentiality of bacteria in the human gut to a healthy life, with profound implications for both agriculture and medicine. Dr. Montgomery points to a “bonafide scientific revolution” in recognizing the failure to nurture the ecosystem in nature and the human body and the associated adverse health effects resulting from pesticide use –21st century diseases, including asthma, autism, bacterial vaginosis, cardiovascular disease, cancer, Crohn’s disease, depression, inflammatory bowel disease, leaky gut syndrome, multiple sclerosis, obesity, Type 1 and 2 diabetes, and Parkinson’s. Also in the Journal, Monsanto’s Roundup (Glyphosate) […]
