April 9, 2019 Minutes

About 120 beekeepers attended the April 2019 meeting at the Oaks at Salem.

Before the meeting, new beekeepers met with Jeremy Hays to go over different methods for feeding bees.

At 7 pm, the beekeeping equipment silent auction began. A variety of items were available including extractors, bottles, books, hive bodies and an observation hive.

The meeting was called to order at 7:30 pm by president Ken Cobb.

After recognizing visitors and new members, it was reported that about 10 swarms have been caught through the WCBA swarm list since the last meeting with more on the way.

April Maness was recognized for her generosity in allowing us to use her beautiful facility for our meetings. The club will provide her and her son each with a nuc of bees to replace the ones they have lost.

Jeremy Hays repeated a call for volunteers to help when we meet at the Oaks at Salem in the summer to help with parking, set up and take down.

Announcements

Certified Beekeeper Program: If you have taken the written portion of the certified beekeepers test, don’t forget to attend a Hands on the Hive for the practical part. Once you pass both parts and successfully keep bees for 4 months you will receive your Beekeepers Certificate.

Carpenter Bee Study – Dr. Elsa Youngsteadt is interested in soliciting volunteers in Raleigh, Cary, or Garner with carpenter bee infestations to place 20 handcrafted benches with different wood types for the study. This is a 5 year committment. For details contact

NCSBA Request – Charles Heatherly needs volunteers to create a display of foods pollinated by bees and other helpers for a tour of the NCSU Bee Lab by legislators. if you are interested in helping.

Speakers Committee – WCBA is looking into getting a renowned speaker to come to our area as a speaker. Justin Wahrenburg, Jeremy Hays and Beth Harris are on the committee. If you would like to join the committee or suggest a speaker, contact Beth.

The next meeting will be held May 14 at the Wake County Commons Building. The beginner workshop will focus on swarm and space management. The meeting speaker will be Kenneth Edmonds of Thermal Hive Industries on the topic of Varroa IPM.

At 7:45 the floor was turned over to Jeremy Hays to introduce the speaker.

Speaker – Joe Milone

Joe Milone, a graduate student at the NCSU Bee Lab presented “Realistic Peticide Exposure and its Effects on Queen and Larval Survival”

He discussed honey bee exposure to pesticides and chemical through a variety of sources, how they enter the hive via wax and bee bread, and their effects on the queen and larvae.

Instead of focusing on just one chemical, he looked at the spectrum of pesticides bees are exposed to and their added effect on hive survival. Joe reminded us that “the dose makes the poison”. He combined the dose and toxicity of various pesticides to create a Hazard Quotient to easily estimate risk. His data shows that commercial hives have a much higher HQ than hobbyists.

In another project he looked at both the genetic susceptibility and exposure together and their effect on Queen development and survival. He compared 8 different stocks from the US with different exposures to pesticides via wax and food. He looked at not how exposure affects the queen herself but the downstream effects in a hive. In general, more managed groups were more susceptible.

Conclusions from the study are

  • Breeding may have unintended effects. Strengthening one characteristic might lead to weakening of others
  • Not all honey bees are the same. Pay attention to stock origin when studying pesticide tolerance.
  • Need to compare detoxification mechanism between groups.

Final take-aways are

  • Multipesticide research is important for honey bee stressor research!
  • Queens can have down stream effects resulting from exposure
  • Genetics play a role in exposure tolerance and breeding programs may have unintended consequences.

After the talk Joe answered questions. The meeting adjourned at 9 pm.
