- 13. 1. Neighbor Relations January 21, 2017 “Did you lose a swarm?” “They’re all over my bird feeder.”
- 20. 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.
- 21. If your colonyhas 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?

- 32. Retrieving Swarms BeeVacuum 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
- 33. 3. Prudent MiteManagement 1. 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 restrictions Rotating protocols
- 34. 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
- 35. Glycerine – OxalicAcid Used in Argentina Very effective Longer term exposure required, slow release Bees must make contact with paper towel Fall meeting – Randy Oliver’s work www.scientificbeekeeping.com
- 36. Recipe Two bottlesfood quality glycerin (Wal-Mart, $3.88) One tub of OA Wood Bleach (Ace Hardware, $8.95)
- 37. Recipe Empty 2bottles of glycerin into a 6” saucepan Refill 1 of these bottles with tap water Heat until 140 to 160 degrees Empty tub of OA, slowly, and stir Keep heat on until 140 to 160 degrees Heat until clear Drop in ½ roll of paper towels
- 41. 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)

- 45. Takes the placeof inner cover
- 46. Late winter foodstores
- 47. Results Added extraprotein (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

- 53. What can Idetect March 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?
- 54. Pesticide Analysis Very expensive($160 per sample) Testing limited Need freshly deceased bees (do not freeze) Pesticides quickly break down
- 55. Drift watch http://mo.driftwatch.org Voluntary registration Needs better participation No enforcement
- 56. End Result Thirteenhives 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
