Study Shows the Benefits of Pesticide-free Pollinator Habitat
(Beyond Pesticides, March 17, 2015) Foraging bumblebees would prefer to dodge traffic rather than pesticides and other agricultural chemicals, according to the results of a new study published in the Journal of Insect Conservation. Researchers from Plymouth University in England discovered that the number of bumblebees observed foraging plants along roadsides was over twice the number located in adjacent patches facing agricultural crops. As both native and managed bees continue to decline throughout the globe, this research strengthens calls from farming and environmental groups to improve agricultural practices through increased on-farm diversity, and sharp reductions in the use of pesticides, particularly systemic chemicals such as neonicotinoids. Mick Hanley, Ph.D., lead author of the study, explains, “There have been hedgerows and field boundaries in these locations for centuries, and even if you go back 50 or 60 years, you would not have seen this phenomenon. Both sides of hedgerows would have been flourishing, and bees and other insects would have been numerous on both sides, but that was before an increase in the use of fertilizers.” However, it is likely the use of agrichemicals that has caused such a stark discrepancy between roadside and farm-side habitats. “Now what you see is […]
