Millions of honeybees were exterminated in South Carolina this week after an attempt to kill mosquitoes possibly carrying the Zika virus went wrong.

Dorchester County officials aerially sprayed a pesticide called naled early Sunday morning, resulting in the death of millions of honeybees and other pollinators. Due to concern regarding four travel-related cases of Zika reported in the county, the chemical was sprayed over 15 square miles in order to eradicate mosquitoes that may further spread the virus. Naled has been used in the United States for over 50 years but has a contested reputation nationwide. The pesticide was banned in the European Union in 2012 after it was deemed to have a “potential and unacceptable risk” to human health and the environment. Conversely, naled has been approved by the U.S. Environmental Protection Agency (EPA) since 1959 and is sprayed over 16 million acres of U.S. land each year.

The scene painted by beekeeper Juanita Stanely was bleak. “On Saturday, it was total energy, millions of bees foraging, pollinating, making honey for winter,” she said in an interview with CNN on Monday, “Today, it stinks of death. Maggots and other insects are feeding on the honey and the baby bees who are still in the hives. It’s heartbreaking.”

Stanley, co-owner of Flowertown Bee Farm and Supply, said that she lost 46 hives and nearly 3 million bees on Sunday with no warning. She explained, “…when they sprayed by trucks; they told me in advance, and we talked about it so I could protect my bees. But nobody called me about the aerial spraying; nobody told me at all.” The pesticide application was the first aerial spray in the area in over 14 years. Dorchester County Administrator Jason Ward said that attempts were made to notify the public about the aerial spraying through an alert on its website posted two days before spraying. He added that county officials also reached out to beekeepers that were on the local mosquito control registry, but that one country employee failed to follow notification procedure.”He made a mistake in terms of going down his list, and failed to call,” Ward said.

Had she been warned, Stanley said that she would have told officials to do their spraying at night.” ‘Do it at night when bees are done foraging,’ I would have told them,” she said, tears filling her eyes, “But they sprayed at 8 a.m. Sunday, and all of my bees were out, doing their work by then.” Though county officials have publicly apologized, they maintain that the pesticide was used as directed. “We followed that recommendation,” said Ward, “which is also the policy laid out by the state, using a pesticide the state has approved for use.”

Dr. Dennis vanEngelsdorp, a bee researcher at the University of Maryland, said that there are ways to eradicate infected mosquitoes without killing invaluable pollinators. He said the issue reaches beyond honey bees, “If you’re killing honeybees, you’re killing a lot of other non-honeybee pollinators, too, and those populations could take a long time to recover.”

University of Iowa receives funding to study, monitor Zika virus

Iowa is among 39 other states and territories to receive more than $16 million from the Centers for Disease Control and Prevention to monitor and study the Zika virus.

Though the amount of funding was not specified, the University of Iowa is the agency within the Hawkeye State that will receive money to study Zika. The UI is the only university to receive funding as state departments of public health were awarded the funds in the other states and territories.

The funding will “establish, enhance, and maintain information-gathering systems to rapidly detect microcephaly – a serious birth defect of the brain – and other adverse outcomes caused by Zika virus infection.” The funding is temporarily being diverted from various public health resources until congress approves of specific moneys for Zika.

Within weeks of the first reported cases of Zika in the United States, officials with the University of Iowa’s State Hygienic Laboratory (SHL) and the Iowa Department of Public Health “were preparing for the worst.” As of May 19, the SHL had tested nearly 200 specimens, most of which were determined to be negative. In addition to six specimens that tested positive for Zika, there were two reports of Dengue virus but zero reports of Chikungunya. Chikungunya and Dengue – both of which are vector-borne similar to Zika – and their impact in the Hawkeye State were discussed during the 2014 Iowa Climate Science Educators Forum.

The first travel-related case of Zika virus in Iowa was reported on February 19 of this year. Since then, eight other case of Zika have been reported. All reports of Zika in Iowa have occurred in adults who had recently traveled to Central or South America or the Caribbean and none of the women who reported the virus were pregnant at the time. The Iowa Department of Public Health provides weekly updates about Zika on its website.
