Though a contributing factor, farmer-applied pesticides are not the primary cause of honeybee colony loss in Virginia, according to Virginia Tech scientists Richard Fell and Carlyle Brewster.
The scientists recently took wax, pollen, and bee samples from more than 110 hives across the state and have analyzed about half of them for pesticide residues.
“We did not find excessive amounts of agricultural pesticides in the hives, but we did find a significant amount of beekeeper-applied miticide,” said Fell, professor emeritus of entomology in the College of Agriculture and Life Sciences.
Intended to kill the invasive, parasitic varroa mite, miticides can also be damaging to bees. Fell urged beekeepers to sample their colonies to determine mite infestation levels before treating. If treatment is necessary, beekeepers should use a miticide that does not cause residue problems, such as formic acid.
As more information emerges on the spread of the Zika virus, Fell also encouraged the public to be mindful that mosquito pesticides are toxic to honeybees and should only be applied when absolutely necessary.

The Zika virus has quickly become a major health threat, and researchers at Virginia Tech are looking for ways to curtail its spread.

The virus, which is primarily spread to humans by the bite of an infected mosquito, has been passed on to a growing number of Americans since early 2016, and the World Health Organization has declared it a Public Health Emergency of International Concern.
Biochemist Zhijian “Jake” Tu is one of several Virginia Tech researchers zeroing in on the Zika virus. Tu is studying genes that turn biting female mosquitoes into males, and he is exploring genetic strategies to stop the transmission of the Zika virus by reducing the number of female mosquitoes. Male mosquitoes do not bite and are harmless to humans, while female mosquitoes bite humans to get the blood they need for egg production.

In Virginia Beach, raising awareness in public schools about the importance of environmental sustainability is a city goal. With nearly 68,000 school-age children in Virginia Beach Public Schools and only one horticulture class offered in Virginia Beach Public Schools and one college Horticulture program regionally, it’s impossible to provide sustainable horticulture education to every student.
Virginia Beach Cooperative Extension sought to fill some of that gap, through five events that succeeded in reaching over 6,200 students.
First and second graders in public schools throughout Virginia Beach participated in Ready, Set, Grow, which taught the importance of plants and how they grow.
Junior Master Gardener Camp taught environmental awareness to underserved youth through Parks and Recreation’s Rehabilitation Program.
Farm Days, sponsored by the Virginia Dare Soil and Water Conservation District, taught students about beneficial insects and habitat preservation.
At the W. W. Moore Juvenile Detention facility in Danville, detained youths are being offered the chance at a green thumb, sponsored by Virginia Cooperative Extension. It’s an opportunity that, for some, can change the course of their future.
Jane Clardy, a former teacher and founder of the facility’s 10-week horticulture program, ran into a former detainee and student, who landed a recurring construction job but had hopes of a future in landscaping.
“He told me he always shows his horticulture certificate when he applies and is interviewed,” Clardy said of the encounter. “He told me his goal is to one day be his own boss and have a landscaping company. I smiled for two straight hours after seeing him.”
The program focuses on basic knowledge related to how plants grow, effective plant care strategies, and the importance of proper plant management practices. Holding these basic skills helps make the youth more attractive to an employer in plant nurseries, lawn care companies, and various grounds maintenance careers.
Applications for the 2017 New River Valley Master Gardener training program are due by Dec. 19.
Are you looking for a way to improve your community through volunteer service? Do you have an interest in horticulture? Do you enjoy sharing your knowledge? If the answer to all of these questions is yes, being a Virginia Cooperative Extension Master Gardener may be right for you.
Applications that can be found online are now being accepted for the New River Valley Master Gardener training program and are due by Dec. 19. Applicants must be able to attend a 60-hour training course and complete 50 hours of volunteer service with Virginia Cooperative Extension during their first year.
The cost for the 60-hour course is $150, which covers the “Virginia Master Gardener Handbook” textbook and other training materials.
The training course will be held from March to May on Tuesday and Thursday afternoons from 1– 4 p.m. at the Hahn Horticulture Pavilion at Virginia Tech. Students will get an equivalent of three college credits worth of knowledge from classes taught by Virginia Tech professors and Virginia Cooperative Extension agents.
