Swarm Trap - May 12th 2023

On Friday, May 12th

• 2:00 PM - active scouting at one swarm trap, zero scouting at other traps 
• 3:00 PM - very active scouting at one swarm trap, zero scouting at other traps
• 6:24 PM - air is thick with bees
• 6:48 PM - the majority of bees settled on the outside of the swarm trap and began to move in
• 8:23 PM - bees reversed and are on the outside of the trap

On Saturday, May 13th

• setup 8-frame deep box near the swarm trap; in the last photo, check out the homemade rectangular UV-reactive blue 8-frame entrance
• add a queen excluder beneath the deep box
• spray the bees with sugar water
• carefully lower the swarm trap
• carefully walk the swarm trap to the deep box
• spray the bees with sugar water
• brush bees into the deep box
• add frames
• move the pheromone lure from the swarm trap to the landing board
• add an inner cover and telescoping lid
• after 2 hours, all the loose bees have reoriented to their new home

On Sunday, May 14th

• add a gallon pail feeder with 32 ounces of 1:1 syrup

I'm guessing that 

• the swarm was hanging very close to their preferred swarm trap, and the scout bees ignored my other swarm traps
  
• this swarm contains more than 1 queen

moving swarm to 8-frame equipment

Today I moved the swarm to 8-frame equipment. In one week, all 5 frames had similar new comb construction on the plastic starter strips. 

I moved the swarm lure to the 8-frame landing board, and the remaining bees entered the 8-frame equipment in under 2 hours - I did not bump bees off the swarm trap. In the last photo, notice the homemade rectangular UV-reactive blue 8-frame entrance.

The bees returned with cream-colored Tulip Poplar pollen and slowly consumed 1:1 syrup.

Swarm Trap - March 28th 2023

The moment I've been waiting for!

On February 20th, I set out two 40-liter swarm traps hanging from crepe myrtle limbs.   Each swarm trap contains:

• 5x deep frames with plastic starter strips
• UV-reactive blue swarm trap entrance
• synthetically produced Nasonov pheromone
  

In another 3 days, scout bees visited the swarm traps.  Though I waited for 33 more days before a swarm would select one of the swarm traps.

From mid-February to early March, Atlanta's maximum temperatures were warmer than expected. On February 21st, the high temperature was 21°F above maximum normals (1991-2020).   

On March 7th, pollen counts soared to 3937 - outdoor surfaces were covered with yellow pollen (pine, oak, sweet gum, hackberry, and birch).    Walking the dog, I discovered bees (mining, carpenter, and European honey) visiting crabapple tree flowers on my street - thanks to Trees Atlanta.

I set 4 hanging swarm traps on 3 properties in my neighborhood, each with: 

• UV-reactive blue swarm trap entrance
• synthetically produced Nasonov pheromone

2 of these traps are on my property and conveniently located where I can watch the swarm trap entrance and the behavior of scout bees from a window. See the video and read page 62 of Honeybee Democracy describing scout bees.

So far, the traps did not attract a swarm - my swarm trap hopes rest with a return to more normal temperatures after this week of frigid spring weather.

Impact of UV-Induced Blue Florescence Entrances concludes:

• UV-reactive blue swarm trap entrances nearly doubled the number of scout bees observed over the control
• Swarms selected the trap with the UV-blue entrance over the control 100% of the time

 method and materials:

• conducted from May to August in 2020 and 2021 in western New York
• 1.25 inch (3.2 cm) circular entrance hole
  
• 1.59 cubic ft (45 liter) cavity volume
• 4 frames without comb + 1 frame with some comb
  
• attached to a tree at a height of 8-10 feet
• 3 locations facing an open field with bee forage
• 2 traps per location 200 feet apart with a 3D printed trap entrance using 1) UV-reactive blue filament or 2) white filament (control)
  
• swarm lure spray applied weekly
• weather permitting, 1 location included scout bee counting between 11:30am-4:00pm
