Disease Carrying Mosquitoes Developing Resistance to Widely Used Mosquito Control Pesticides   (Beyond Pesticides, July 1, 2021) Yellow fever mosquitoes (Aedes aegypti) are evolving resistance to the pyrethroid insecticide permethrin, according to a study published by Colorado State University, highlighting the need to adopt ecologically-based mosquito management. Widespread, intensive use of the pesticide in mosquito control has allowed genetic mutations to persist among these mosquito populations, causing subsequent resistance to permethrin.  Insecticide resistance has been an issue since the introduction of DDT (dichlorodiphenyltrichloroethane) in the 1940s.

Threat to Ocean Health: Pesticide Resistant Fish Lice Plague the North Atlantic Ocean   (Beyond Pesticides, June 3, 2021) A report published in Royal Society Open Science finds pesticide-resistant parasitic lice (Lepeophtheirus salmonis) are endangering wild and farmed fish populations in the North Atlantic. Extensive use of pesticides to rid the parasite has led to widespread resistance to multiple pesticides, prompting increasing infection rates among North Atlantic salmon populations.

Scientists Warn of Another Pandemic If Officials Continue to Ignore Explosion of ‘Antimicrobial Resistance’  (Beyond Pesticides, October 16, 2020) The Lancet has published an article that identifies several of the multiple and interacting crises the U.S. and world face, with a focus on another “looming potential pandemic . . . a rise in .e, whose rise threatens the health of people in the USA and globally.” It calls on leaders in the U.S. and beyond, asking that even as they address the current coronavirus pandemic, they also attend to the antimicrobial resistance (AMR) problem, which is a growing threat to public health.

EPA Registers Toxic Pesticide for Use on GE Soybeans without Required Opportunity for Public Comment   (Beyond Pesticides, April 7, 2020)     'Last week, the U.S. Environmental Protection Agency (EPA) registered a carcinogenic herbicide for new uses without following  the required public notification and comment process, the Midwest Center for Investigative Reporting (MCIR) reports. The chemical in question, isoxaflutole, is a broadleaf weedkiller that can now be applied to genetically engineered (GE) soybeans in half of U.S. states. Health and environmental groups are outraged by EPA’s furtive move, accusing the agency of colluding with the pesticide industry.   A 2018 study found no evidence that rotating herbicides is an effective strategy to manage weeds. Farmers with high levels of resistance retain high weed density, no matter what new chemical are thrown at them. In fact, once a weed develops resistance to one herbicide, it is much more likely to develop resistance to other weedkillers.'

Cockroaches Rapidly Develop Resistance to Nearly Every Pesticide, Requiring Alternative Approach   (Beyond Pesticides, July 2, 2019)    'Rotating the insecticides used each month resulted in cockroach populations that were relatively stable or increased, while the treatment with a mixture of pesticides resulted in a population explosion. And researchers found that for cockroaches that survived after an application of one chemical didn’t develop resistance merely to that one chemical or even class of chemicals, they also developed resistance to pesticides in other chemical classes. This occurred even if they had never been exposed to these new pesticides in their life.'    ' In the face of pesticide resistance, integrated measures that focus on structural, mechanical, and cultural pest management practices must become standard practice for this notorious pest.'   article also explains the appropriate approach, and links to alternatives. SNAP Comment: The only astounding thing about this research is that it took so long to be done! Surely, the fact that monthly spraying were needed for the last 60 years at least should have been a hint! especially when studies  have shown for at least 10 years that properly defined and used 'integrated pest management' worked!

Pesticide Use Kills Off Mosquito Predators Faster than Target Mosquitoes   (Beyond Pesticides, June 6, 2019) 'Pesticide use eliminates pest predators and permits mosquito populations to flourish, according to research conducted in Costa Rica by scientists at Utah State University.''Pristine areas had 58% fewer mosquitoes than the chemical-dependent orange groves surveyed. Moreover, chemical-dependent groves have zero damselfly predators within any bromeliad plant sampled; none at all. While organic orange groves have lower levels of damselflies detected than pristine areas, they still contain a viable population of the species...Discussions with conventional farmers in the region reveal that the organophosphate insecticide dimethoate has been used for up to several decades to manage psyllid pests...To determine whether pesticide resistance is involved, researchers tested and compared mosquitoes from chemical-intensive groves and pristine areas. Mosquitoes within chemical-dependent groves are able to endure significantly higher levels of pesticide exposure, up to ten times (10x) more than mosquitoes find in pristine areas.

Is Your Yoga Mat or Gym Breeding Antibiotic Resistant Bacteria?  (Beyond Pesticides, January 2, 2019)  'Every antibacterial chemical tested by researchers showed up in every facility investigated. Gyms, rooms with higher moisture levels, and those with carpeted flooring all had elevated levels of antibacterials compared to other facilities...Most concerning is the finding that the number of microbes with antibiotic resistant genes was higher in facilities with elevated concentrations of triclosan and its chemical cousin triclocarban. And the type of resistance microbes display is not limited to triclosan—they exhibit a diverse range of resistance measures. “Those genes do not code for resistance to triclosan,” Dr. Hartmann clarifies. “They code for resistance to medically relevant antibiotic drugs.”'

Pesticide Use Found to Surpass ‘Planetary Boundaries’ for Resistance   (Beyond Pesticides, November 16, 2018)    Pesticides and biocides used to control bacterial infections in humans and weeds and pests in agriculture are surpassing ‘planetary boundaries’ within which human civilization can continue to rely on these biocides.

Weeds on Missouri Cropland Found To Be Resistant to Six Different Herbicides  (Beyond Pesticides, August 2, 2018) 'Weed scientists from the University of Missouri (UM) have just published evidence of a water hemp population resistant to six different herbicides. The study is sending shock waves throughout the chemical-intensive agricultural community, particularly in light of the plant’s resistance to 2,4-D.'  This woud certainly affect the effectiveness of 'Enlist Duo, developed by DowDupont in an attempt to address widespread weed resistance to glyphosate. Enlist Duo is an herbicide containing both glyphosate and 2,4-D, and is intended to be sprayed only on crops genetically engineered (GE) to tolerate exposure to both chemicals. However, with growing reports like this, many farmers may begin to rethink their approach.'

Lice Found Resistant to Common Insecticide Treatment  (Beyond Pesticides, August 20, 2015) Just as children go back to school, research finds that lice in 25 of 30 states in a U.S. study have developed resistance to common over-the-counter treatments like permethrin, calling into questions the justification for exposing children to a neurotoxic and carcinogenic pesticide and elevating the need to consider nontoxic alternatives....Classified as a synthetic pyrethroid insecticide, permethrin is “likely carcinogenic” and a suspected endocrine disruptor, immunotoxic, neurotoxic, and highly toxic to fish, aquatic animals, and bees. Dr. Yoon and his colleagues describe the threefold mutations that lice have developed over time due to the constant use of synthetic pyrethroid insecticides. This new finding builds on his team’s previous research, which found that 99.6% of lice are resistant to chemical treatment, adding weight to the fact that chemical treatments not only are unnecessary given effective least-toxic alternatives, but also are not able to provide the lice control that manufacturers claim.
