(Beyond Pesticides, April 7, 2026) In the International Journal of Molecular Sciences, a study of gestational (during pregnancy) exposure to the neonicotinoid insecticide thiacloprid shows epigenetic effects (alterations in genes without altering underlying DNA) within prostate tissues. To analyze the role of gene expression in subsequent generations after initial thiacloprid exposure, the authors exposed pregnant outbred Swiss mice to the insecticide in order to assess the offspring for multiple generations. As a result, the researchers from the UniversitĂ© de Rennes in France state, “Our study revealed that exposure to thiacloprid induces [cell] proliferation and is associated with epigenetic alterations in the sperm of genes important for prostate development.” Increased cell proliferation in the prostate can cause the development of conditions such as benign prostatic hyperplasia (BPH) and prostatic intraepithelial neoplasia (PIN), and lead to prostate cancer. The study also finds elevated levels of specific biomarkers within the prostates of both the first and third generations, including phosphorylated histone H3, a marker crucial for cell division. Hox gene expression in both generations was also impacted, which plays a role in prostate development, based on the altered DNA methylation (abnormal changes) in the sperm of the analyzed mice. “In this study, we […]

(Beyond Pesticides, March 4, 2026) In the International Journal of Epidemiology, researchers from France assess the risks of kidney cancer with a wide range of agricultural activities and tasks, finding that occupational exposure heightens kidney cancer risk. In studying participants from the French AGRIculture and CANcer cohort (AGRICAN) with incident kidney cancer, elevated risks of disease development between 25-56% are documented for both men and women engaging in agricultural activities. In men, the authors find increased kidney cancer in those “working with rapeseed and sunflowers, and tasks related to other crops such as corn, wheat/barley, beet, and tobacco.” In women, an increased risk is noted for winegrowers and corn growers. “Pesticide use (on fields and/or seeds) was associated, for both sexes, with these crops, showing exposure-response relationships with crop area and work duration,” the researchers state. This study, of a large cohort of agricultural workers, highlights the disproportionate risks of adverse kidney health to farmworkers directly handling pesticides or encountering pesticide residues on recently treated products. According to the World Cancer Research Fund, kidney cancer is the 14th most common cancer worldwide, affecting men more often than women. Kidney cancer incidence and mortality have increased globally, with various causes, such […]

(Beyond Pesticides, February 10, 2026) Species that are integral to pest management allow for crucial ecosystem services that negate the need for pesticides in agricultural or land management practices. In a study published in Agriculture, Ecosystems & Environment, researchers from France find pesticide-free fields promote carabid beetles and spiders, generalist arthropod predators that consume slugs, aphids, and mites, that in turn support healthy, organic systems. The study findings highlight the importance of utilizing farming practices that promote biodiversity and foster natural enemy populations as a pest management strategy.  “In this study, we assessed the assemblages of emerging and circulating ground-dwelling carabids and spiders during four months in a continuous mosaic of pesticide-free winter-sown crops under contrasted tillage regimes (minimum vs. conventional tillage) and sown flower strips bordering fields,” the authors describe. They continue: “We detected clear patterns, with high in-field carabid and spider overwintering densities than in adjacent flower strips… Our results also demonstrate the key role of pesticide-free fields under minimum tillage, acting both as a high-quality overwintering site for some dominant carabid species and as a source habitat, as several predator species activity-density responded positively to the increased area of minimum tillage fields in the surroundings.” Background […]

(Beyond Pesticides, December 5, 2025) A study published this month in Environmental Pollution analyzes the role of neonicotinoid insecticide exposure on bird populations, finding a significant negative effect of imidacloprid use on insectivorous bird abundance. In comparing the effects of the insecticide imidacloprid on bird abundance in France before and after the 2018 ban, the researchers show a weak recovery of bird populations after 2018. The persistent nature of imidacloprid, however, as well as the continued use of other petrochemical pesticides that have adverse effects on bird species, continues to impact populations of all types of birds and other wildlife, leading to cascading impacts on biodiversity.   “Our study shows that imidacloprid is a major covariate of the abundance of birds, in addition to other pesticides that are also negatively related to bird populations, and that these effects are not uniform across species,” the authors report. They continue in saying that the relationship between neonicotinoids and bird abundance varied across bird diets, as “the abundance of insectivorous birds was consistently lower under increasing pesticide use, in particular imidacloprid.” Background As shared in the study and on Beyond Pesticides’ Birds page, bird species can be exposed to pesticides directly through ingestion […]
