Pyrethroid Comments- Act Today! DDL. Midnight July 7th
We apologize for the late notice of this ACTION, as the deadline for comments to EPA is Friday, July 7 at midnight. The PSC computer was hacked, held for ransom, wiped clean, then restored—but it delayed getting this information to you.
Send your comments today concerning the registration review of pyrethroids. We make it easy for you by providing the link, and text to copy and paste into the online EPA docket comment section.
Pyrethroid Research shows:
o These products are highly toxic to bees;
o During 2015, pyrethroids were applied to over one million acres of orchards alone, 9a as well as millions of acres of soybeans, sunflowers, alfalfa, and other crops;
o The repellency aspect of pyrethroids alters foraging behavior in honey bees;
o Sub-lethal exposure to pyrethroids impacted bee behavior over a 24-hour period;
o Pyrethroid-treated bees traveled 30-71% less than control bees;
o Esfenvalerate and permethrin decreased social interaction time between 43% and 67%;
o Permethrin exposure contributed to bees spending five times more in the food zone; 10
o Inadequate data exists on honey bee exposure to pesticides from the use of commercial formulations, bottle mixes, and common tank mixes in experiments instead of active ingredients, with a special assessment of co-formulants (quantitative exposure and effects);
o The air matrix within the colony must be explored in order to complete current knowledge on honey bee pesticide exposure;
o Pyrethrins alone provide limited crop protection because they are not stable;
o Pyrethrin toxicity increases with higher water temperatures and acidity;
o Natural pyrethrins are contact poisons, but can be detoxified by the insect. “To delay the enzyme action so a lethal dose is assured, micro-encapsulation (zeon technology) is commonly used, this significantly alters the RT25 breakdown.” 15 Microencapsulation creates RT25s measured in days, not hours. Additionally, applicators commonly add other classes of pesticides to the tank which significantly alter the toxic profile (Extension Toxicology Network, Cornell University, 3/94);
o Pyrethrins may be harmful for up to seven days; 11.9 hours in water, 12.9 hours on soil surfaces;
o In the absence of light, pyrethrin breaks down more slowly in water taking 14-17 days to degrade; if the water is acidic pyrethrin did not readily degrade;
o Half-lives of pyrethrin in sediment are 10.5-86 days.

Create one powerful, influential, fully staffed national organization
Many organizations across North America and around the world have been working tirelessly to enhance pollinator stewardship and survival. Consider supporting them in honor of their commitment and devotion in taking initiative to implement change to support the preservation of pollinators. The Bee Audacious conference, although not an official ‘organization’ was an exemplary initiative, of a “collaborative working conference using dialogue to envision bold evidence-based ideas through which honey bees, other bees, beekeepers and pollination managers could prosper.” It was held in Marshal, CA December 11-13, 2016.
The Bee Audacious participants acknowledged the hard work happening in North America and around the globe to protect pollinators. They also noted the excess and duplication of ‘save the pollinator’ initiatives that are competing for money to fund stewardship and research. As mentioned in the previous newsletter, audacious ideas called for a national organization or alliance with a two-pronged approach:
• “A National Pollinator Alliance would centralize efforts and develop a unified message for lobbying and public outreach that would address issues common to all bees (wild and managed)”
• “A Bee Corps focused on assisting beekeepers (commercial and small scale).” (p.58)
Let’s look at some of the organizations in the United States that currently fit the criteria the Bee Audacious groups agreed were essential to enhancing communication and collaboration in the pollinator protection and beekeeping industry. These organizations are making inroads at the local, state and federal levels. They are doing important work on behalf of beekeepers and pollinators.
What is killing the bees?
Neonicotinoid insecticides are used to manage insect pests on fruits and vegetables that also rely on pollination. In addition, these crops frequently neighbor and are rotated with large acreage field crops containing neonicotinoid seed treatments such as corn, resulting in potential non-target exposure of honey bees to insecticides. This video highlights current efforts by Purdue entomologists—Ian Kaplan, Christian Krupke, Rick Foster—through a USDA-SCRI (specialty crop research initiative) grant to evaluate the impact of neonicotinoids on managed and wild pollinators of cucurbits in the Midwestern U.S. and determine how best to balance pest management with conserving pollinator health.

“Physiological thermal limits predict differential responses of bees to urban heat-island effects”
Authors: April L. Hamblin, Elsa Youngsteadt, Margarita López-Uribe and Steven D. Frank, North Carolina State University, Published: June 21, Biology Letters, DOI: 10.1098/rsbl.2017.0125
Changes in community composition are an important, but hard to predict, effect of climate change. Here, we use a wild-bee study system to test the ability of critical thermal maxima (CTmax, a measure of heat tolerance) to predict community responses to urban heat-island effects in Raleigh, NC, USA. Among 15 focal species, CTmax ranged from 44.6 to 51.38 °C, and was strongly predictive of population responses to urban warming across 18 study sites (r2 = 0.44). Species with low CTmax declined the most. After phylogenetic correction, solitary species and cavity-nesting species (bumblebees) had the lowest CTmax, suggesting that these groups may be most sensitive to climate change. Community responses to urban and global warming will likely retain strong physiological signal, even after decades of warming during which time lags and interspecific interactions could modulate direct effects of temperature.

In an effort to track this problem and gather better data, the Bee Informed Partnership, Michigan State University, and the University of Maryland – College Park have launched MiteCheck. The program allows beekeepers to report mite counts and infestations — and to track geographic trends in mite populations.

Pollinator Stewardship Council Technology updates
Due to our computer being hacked, held for ransom, wiped clean, then restored, locked out of our Facebook page (and Facebook itself provides NO customer service to assist), and malware on our website (also cleaned, and now fully protected)—we have made some technological changes.
