1. Neighbor Relations January 21, 2017
“Did you lose a swarm?”
“They’re all over my bird feeder.”

2. Swarm Prevention Excessive feeding may cause congestion
Lack of empty drawn comb
Competition between incoming nectar and brood
Imbalance of too many young bees to older bees
Inferior queens (perhaps due to age)
Easiest solution: Add more hive bodies and gently intersperse empty frames into brood nest.
![Page 21: Emba 2017 05-10](https://reader031.vdocument.in/reader031/viewer/2022022415/5a64920c7f8b9a88568b4bdd/html5/thumbnails/21.jpg)
If your colony has swarmed… Option 1: Cut out all but one, maybe two swarm cells
and leave hive intact.
Option 2: Divide up the frames with swarm cells into nuc boxes. Reduce the swarm cells to one, maybe two, cells per nuc box.
Key: do you know the difference between swarm cells and supersedure cells?

Retrieving SwarmsBee Vacuum highly recommended
Vacant hive body with drawn comb*
Solid bottom highly preferred by bees
A drop (only one) of swarm lure
Inner cover with extended lip
Queen catcher to hold queen
*means extra equipment on hand

3. Prudent Mite Management1. Do I need to treat for mites?
Assessment tools and timing (late July)
2. How do I want to manage my bees?Integrated Pest Management (IPM)
What kind of bees did I acquire? (genetics)
3. Timing of application and restrictionsRotating protocols
![Page 34: Emba 2017 05-10](https://reader031.vdocument.in/reader031/viewer/2022022415/5a64920c7f8b9a88568b4bdd/html5/thumbnails/34.jpg)
Late Summer – Mite Treatments
Oxalic Acid (organic, inexpensive, approved)
1. Vaporization (sublimation) Very effective on the mites
Tough on the bees
Application precautions (respirator mask)
2. Dribble Method – Dr. Marion Ellis, U of NE Not as effective on the mites
Easier on the bees
Very safe for beekeepers
Both methods: Quick and easy, broodless period
![Page 35: Emba 2017 05-10](https://reader031.vdocument.in/reader031/viewer/2022022415/5a64920c7f8b9a88568b4bdd/html5/thumbnails/35.jpg)
Glycerine – Oxalic Acid Used in Argentina
Very effective
Longer term exposure required, slow release
Bees must make contact with paper towel

4. Feeding Bees Last fall – timely rains, good foraging, heavy hives
Warm winter – heavier consumption
Early spring – hungry hives
too cool to feed syrup (50 degrees)
Candy boards (cooked)
Sugar Bricks (5# sugar to ½ cup water)
Ted’s Mush (1 cup water, 4# sugar)
“Mountain Camp” method (dry sugar)

ResultsAdded extra protein (Dadant’s AP23)
10 cups to 40 lbs sugar
Candy readily consumed
Colonies survived
Hives did not brood up until I started 1:1 syrup
SHB not a problem until rain seeped in

What can I detectMarch 24th – too wet to spray (?)
No crop or pests to spray (?)
Anhydrous Ammonia for corn (?)
Hives sit within 40 yards of rail road line
Power line company had trees trimmed
Water drainage plentiful – runoff (?)
Plain vandalism?
![Page 54: Emba 2017 05-10](https://reader031.vdocument.in/reader031/viewer/2022022415/5a64920c7f8b9a88568b4bdd/html5/thumbnails/54.jpg)
Pesticide AnalysisVery expensive ($160 per sample)
Testing limited
Need freshly deceased bees (do not freeze)
Pesticides quickly break down
![Page 55: Emba 2017 05-10](https://reader031.vdocument.in/reader031/viewer/2022022415/5a64920c7f8b9a88568b4bdd/html5/thumbnails/55.jpg)
Drift watchhttp://mo.driftwatch.org
Voluntary registration
Needs better participation
No enforcement

End ResultThirteen hives affected– all queen right
Populations obviously diminished
Fed 1:1 syrup
Four weaker hives continued to decline
Stronger hives made a recovery
Nine hives seem to be making a comeback
![Page 57: Emba 2017 05-10](https://reader031.vdocument.in/reader031/viewer/2022022415/5a64920c7f8b9a88568b4bdd/html5/thumbnails/57.jpg)
