Neonicotinoid Insecticides Adversely Affect Nervous System Health, According to Study

(Beyond Pesticides, January 19, 2023) Chinese study. 'Research published in Environmental Health Perspectives finds the presence of nine various neonicotinoids (neonics) and six neonic metabolites within human cerebrospinal fluid (CSF)

Researchers collected CSF samples from patients experiencing similar symptoms with a different disease/clinical diagnosis (i.e., “mostly viral encephalitis, encephalitis other than viral encephalitis, leukemia, cerebral hemorrhage, cerebral laceration, urinary tract infection, respiratory failure, pulmonary tuberculosis, and posterior circulation ischemia”). 

Ninety-nine percent of the 314 CSF samples contain at least one neonic. Of the 314 CSF samples, nine percent (28) have a single neonic compound, 84 percent (265) have between 2 and 6, and six percent (19) have between 7 and 10 neonic compounds. Nine of these neonics in CSF samples are nitenpyram (NIT), thiamethoxam, imidacloprid, acetamiprid (ACE), thiacloprid, clothianidin, flonicamid, imidaclothiz, and sulfoxaflor. Additionally, six neonic metabolites are present in CSF: N-desmethyl-thiamethoxam, olefin-imidacloprid, 5-hydroxy-imidacloprid, N-desmethyl-acetamiprid (N-dm-ACE), thiacloprid-amide, and 6-chloronicotinic acid.

Growing Sunflowers Near Honey Bee Colonies Helps Reduce Mite Problems

(Beyond Pesticides, January 18, 2023) Sunflower plantings have the potential to significantly reduce mite infestations in nearby honey bee colonies, according to research recently published in the Journal of Economic Entomology by researchers with the U.S. Department of Agriculture (USDA).

For every doubling of sunflower crop production, models employed show a nearly 1/3 decrease in varroa mite infestation. For the fall pollen feeding experiment, colonies fed sunflower pollen saw a 2.75 fold reduction in the intensity of Varroa infestation compared to the artificial pollen treatment. For the spring feeding, Varroa was found in only one-third of hives sampled. Neither the fall nor spring feed experiment, or the individual caged bee experiment saw a significant effect on viral loading or Nosema prevalence, however.

Pesticides Not Only Linked to Parkinson’s Disease Development, But Accelerating Disease Symptoms

(Beyond Pesticides, January 12, 2023) Exposure to certain pesticides among individuals diagnosed with Parkinson’s disease (PD) can increase the risk of symptom progression. According to a study published in Science of the Total Environmentnearly 20 percent of pesticides associated with the onset of PD also increase the risk of faster decline in motor and non-motor function.   Using a geographic information system (GIS) tool to gather information on ambient exposure to pesticides in residences and workplaces via California Pesticide Use Report records and land use records. The researchers examine the association between 53 pesticides with links to PD onset to determine PD symptom progression for five years and 2.7 years (respectively) for two patients.   

Of the pesticides with links to PD onset, ten or ~18.8 percent (i.e., copper sulfate pentahydrate, 2-methyl-4-chlorophenoxyacetic acid MCPA dimethylamine salt, tribufos, sodium cacodylate, methamidophos, ethephon, propargite, bromoxynil octanoate, monosodium methanearsonate MSMA, and dicamba) have associations with faster symptom progression. 

SNAP comment:  dicamba is used in most lawn care herbicide formulations. There are currently 83 copper sulfate, 95 MCPA , 4 ethephon,107 dicamba,and 0 tribufossodium cacodylate, methamidophos, propargite, bromoxynil octanoate, monosodium methanearsonate MSMA products registered in Canada although some have been historically registered.

Neonicotinoid Insecticides Add to the Growing List of Chemicals that Transfer between Mother and Fetus

(Beyond Pesticides, January 4, 2022) A study published in Environmental Science and Technology finds neonicotinoids (neonics) and their breakdown products (metabolites), like other chemical pesticide compounds, can readily transfer from mother to fetus. 

 Levels of five neonics (acetamiprid, imidacloprid, clothianidin, thiacloprid, and thiamethoxam) and two metabolites of acetamiprid and imidacloprid were measured.

The most abundant neonic in mothers’ serum (MS) and cord serum (CS) samples is imidacloprid, whereas acetamiprid’s metabolite is the most abundant in CS and MS. Both parent and metabolite neonics have a high ransplacental transfer efficiencies (TTE), with imidacloprid having the highest transfer rate (1.61). Even the neonic with the lowest TTE of 0.81, thiamethoxam, is within the high TTE range, indicating proficient placental transfer of these chemicals from mother to fetus. Researchers identify that transplacental transfer of these chemicals mainly occurs through passive mechanisms depending on chemical structure.

Study Connects Neonicotinoids to Liver Damage Ignored by EPA

(Beyond Pesticides, January 11, 2022) Neonicotinoid insecticides can have detrimental effects on liver health, according to research published in the Journal of Hazardous Materials. (Chinese study)

 Scientists determined the amount of eight neonicotinoids in bile samples, including acetamiprid, clothianidin, dinotefuran, imidacloprid, imidaclothiz, nitenpyram, thiacloprid, and thiamethoxam.  

Researchers found that neonicotinoids are neither metabolized by the liver nor excreted by urine. Of all samples taken, at least one neonicotinoid was detected in 99% of individuals tested. However, different neonicotinoids were found to act in different ways. While the detection of acetamiprid was low (1% of samples), 97% contained nitenpyram. The widely used insecticide dinotefuran was detected in 86% of bile. Detections did not appear to differ between participants of different health backgrounds.(cancer vs control).

The results led scientists to believe that neonicotinoids found in bile will eventually be absorbed again by the intestines, make their way into blood, and eventually one’s liver. Biomarkers tested, such as cholesterol, bilirubin, and bile acids, were found to correlate with higher concentrations of certain neonicotinoids. Of the various neonicotinoids, dinotefuran, thiamethoxam, and clothianidin were found to pose the greatest risk to liver health.

Pollinator Decline Leads to Crop Losses, Malnutrition, and Highest Threat to Low-Income

(Beyond Pesticides, January 10, 2023) Pollinator losses are responsible for reducing the global production of nuts, fruits, and vegetables by 3-5%, and this loss of healthy, nutrient-dense food is resulting in over 425,000 excess deaths each year, according to research published late last year in Environmental Health Perspectives.

Insecticidal Bed Nets Contribute to Resistance in Bed Bug Populations

(Beyond Pesticides, January 5, 2022) The use of insecticidal bed nets (IBNs) to prevent mosquito bites in malaria-endemic communities can result in resistance developing in secondary pests like bed bugs, according to research published in Parasites and Vectors. Decreased efficacy against bed bugs and other non-mosquito pests may result in misuse of both mosquito adulticides and bed nets, hampering efforts to stop the spread of malaria and other insect-borne disease.

Survey Technique Increases Agricultural Resiliency and Protects Pollinators; Higher Species Diversity in Organic

(Beyond Pesticides, December 21, 2022) Imagine plucking a flower and being able to find out every insect that recently visited that plant. By evaluating the environmental DNA (eDNA) left behind by insect pollinators alongside visual assessment surveys, a new study is providing an innovative way for farmers to improve pollination and protect on-farm biodiversity.   Scientists also conducted visual monitoring, whereby an observer stood between two orchard rows and recorded all flower visitors within roughly eight feet of themselves. The two methods of observation provide somewhat differing, yet complimentary results.

Integrated Weed Management: Biological Control Options (SK Prairie Conservation Action Plan -PCAP) 40 minute Youtube video.

Speaker: Sheena McInnes, Frenchman - Wood River Weed Management Area and SODCAP Presentation summary: The presentation will be mostly a video introduction of two grazing experts speaking on using cows and goats to control weeds.

Lee Sexton started with sheep but found goats more effective and acceptable to SK cattle producers for integrated weed management as they mostly don't eat grass. Lee mentions Leafy Spurge control. He assesses the site and can train his goats to eat the target weeds. sextongc@icloud.ca 

Ralph Corcoran is a trained in holistic manager with cattle and is using the approach to rehabilitate the pastures on his farm. He has had success with controlling absinthe, burdock, thstle and even some leafy spurge by intensively grazing at the right time and rotation. Sheep or goat following cattle work good on Leafy Spurge. "With small paddocks, you can fix one problem at a time. it really works well." Stop the overgrazing. rlcorcoran@sasktel.net

Mother and Child Health: Learning Disorders and Prenatal Pesticide Exposure Study Results Released

(Beyond Pesticide, December 20, 2022) A meta-analysis published in Chemosphere finds prenatal pesticide exposure, or pesticide exposure during pregnancy has a positive association with autism spectrum disorder (ASD) and attention deficit/hyperactive disorder (ADHD). Particularly, exposure to chemical classes organophosphate (OP) and pyrethroid (PYR) insecticides, in addition to the mother’s age during pregnancy (≥30 years old), increased the risk factor of ASD. ADHD risk increases among offspring whose mothers encounter organochlorine pesticides (OCPs) during gestation.

Denying Science, Manufacturing Doubt: Monsanto/Bayer’s Promotion and Defense of Glyphosate/Roundup

(Beyond Pesticides, December 16, 2022) A report released last week — Merchants of Poison: How Monsanto Sold the World on a Toxic Pesticide — exposes not only Bayer/Monsanto malfeasance in its “promotion” of its glyphosate-based herbicide products, including the notorious Roundup®, but also, the broader landscape of corporate efforts to white- or green-wash products that companies know are harmful to people and the environment. The report was issued by U.S. Right to Know (USRTK, a nonprofit investigative research group focused on promoting transparency for public health), Friends of the Earth (FOE), and Real Food Media. It carries the pithy subtitle, “A case study in disinformation, corrupted science, and manufactured doubt about glyphosate,” a description cited by the Friends of the Earth press release as “at the core of the pesticide industry’s public relations playbook.”

Ultraviolet Light Researched as a Pest Control Technique

(Beyond Pesticides, December 14, 2022) Ultraviolet (UV-C) light has the potential to successfully manage mite (Tetranychus urticae) populations without reducing yields or resorting to toxic pesticides, according to research published by scientists at University of Florida. “Since very few miticides (sprays) are currently effective in suppressing twospotted spider mites in strawberries, the use of UV light provides an effective physical control method that can be used in fields and in high-tunnel strawberry production systems,” says study author Sriyanka Lahiri, PhD. The findings provide an encouraging technique for farmers, but further investigation is needed to observe the success of this approach in other cropping systems.

Estrogen-Mediated Cancers in Humans Have Links to Endocrine Disrupting Pesticides

Estrogen-Mediated Cancers in Humans Have Links to Endocrine Disrupting Pesticides

(Beyond Pesticides, December 13, 2022)  Adding to the science, a review published in Environmental Exposure, Biomonitoring and Exposure Assessment highlights how specific estrogen-mimicking pesticides increase the risk of disease, particularly hormone-related cancers among women (i.e., breast, ovarian, endometrial cancer) and men (i.e., testicular, prostate cancer). Like pesticides, endocrine disruptors are xenobiotic (i.e., chemical substances foreign to an organism or ecosystem). 

Pesticides are one of the most potent xeno-estrogenic compounds, as estrogenic strength and environmental half-life exceed those of other xeno-estrogenic compounds. Focusing on organochlorine pesticides (OCs), the study evaluates the chemical effects on the physiological (anatomic) system to increase cancer risk. Using human studies, researchers assessed how estrogen-medicated cancer develops in women and men. Various OCs, including aldrin, dieldrin, endosulfan, HCH, DDT, 2,4,5-trichlorophenoxyacetic acid, phenoxy acid herbicides, and methoxychlor, have associations with hormone-related cancers. 

Despite the ban on many OCs across the globe, these chemicals remain in the environment. Many OCs can exist in the body for at least three to six years, in soil for decades, and in water for at least a century. Moreover, consumption of food and water resources contaminated with OCs can cause these chemicals to bioaccumulate in the body, resulting in the biomagnification of OCs.

Ocean Health: Environmental Pollutants Threaten Humpback Whale Reproduction and Offspring

(Beyond Pesticides, December 6, 2022) Persistent organic pollutants (POPs)—including banned pesticides—present a health risk to humpback whales (Megaptera novaeangliae), according to a study published in Environmental Pollution. Regarding female humpback whales, levels of POPs in blubber are higher in juveniles and subadults than in adults, primarily from the transference of contaminants from the mother to her calf. Organochlorine compounds (OCs), such as organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs), are well-known persistent organic pollutants. 

Overall, the most abundant POPs are PCBs, followed by DDTs and chlordane. PCB levels are above the estimated threshold for adverse health effects.   This report demonstrates that exposure to chemical contaminants adversely impacts marine mammal health globally. The study notes specific long-term health concerns among the humpback whale population not described in previous reports, including reproductive toxicity, immune dysfunction, and increased susceptibility to disease.

This article also lists other studies listing chemicals that contaminate marine mammal species BPA (plasticiser), the pesticides triclosan and atrazine, and “inert” ingredients from pesticide products

Pest Management Regulatory Agency 2020 2021 Annual Report (Health Canada, 2021)

'Sales of pest control products in Canada have increased from 101.1 million kg of active ingredients (kg a.i.) in 2014 to 121.3 million kg a.i. in 2018 (Figure 2). In 2018, 71.1% of pesticide sales in Canada were agricultural sector products (Figure 3), whereas 24.3% were non-agricultural sector products, and 4.5% were domestic sector products. Figure 2. Quantity of pesticides sold in Canada (2014–2018)  Glyphosate remained the top active ingredient sold in Canada in 2018 (Table 1). Six of the top 10 active ingredients sold in 2018 had been among the top 10 selling active ingredients since 2014. These top 10 active ingredients accounted for 68.7% of all pesticides sold in Canada in 2018. (p.11)

SNAP Comment: An pesticide use increase of 16.65% in the active ingredient glyphosate use in 5 years. Lots of interesting gems in this report
