They broke cluster and went into one of my traps so I got them back so all's well that ends well I guess.

MB is correct, but I would give them 3 days if the question was, "How long before a new beek should be able to find any queen cell that has been started". :wink:

Thanks for this - its good to have the 'for people like me who have no idea what they're doing' answer along with the expert answer.

I guess anything is possible Jim....but there were 2 distinct clusters up in this tree 40 feet up maybe 10 feet apart they swarmed out maybe 1.5 hours apart....no way to get to them to retrieve the. One of the clusters has now dissipated and the other didn't seem to grow so I don't think they merged so they either went back to the hive or moved off I couldn't tell which but the other is still there.....I set up an additional swarm trap and have heavy scout activity at both traps....and several empty hive boxes that have frames in them in storage so will most likely get them back its just odd the sequence of events.

I guess all these unexpected occurrences are part of working from home and having the home yard hives outside my window....looking at the hives now nothing is out of the ordinary so if I hadn't seen it happen i would be clueless to the events ever occurring ;-P

One possible cause of the alarming bee mortality we are witnessing is the use of the very active systemic insecticides called neonicotinoids. A previously unknown and harmful effect of neonicotinoids has been identified by researchers at the Mainz University Medical Center and Goethe University Frankfurt. They discovered that neonicotinoids in low and field-relevant concentrations reduce the concentration of acetylcholine in the royal jelly/larval food secreted by nurse bees. This signaling molecule is relevant for the development of the honey bee larvae. At higher doses, neonicotinoids also damage the so-called microchannels of the royal jelly gland in which acetylcholine is produced. The results of this research have been recently published in the eminent scientific journal PloS ONE.
"As early as 2013, the European Food Safety Authority published a report concluding that the neonicotinoid class of insecticides represented a risk to bees," said Professor Ignatz Wessler of the Institute of Pathology at the University Medical Center of Johannes Gutenberg University Mainz (JGU). "The undesirable effect of neonicotinoids now discovered is a further indication that these insecticides represent a clear hazard to bee populations and this is a factor that needs to be taken into account in the forthcoming reassessment of the environmental risks of this substance class." Working in collaboration with Professor Bernd Gr?newald of the Bee Research Institute at Goethe University Frankfurt, Professor Ignatz Wessler and his team uncovered this previously unknown damaging effect of neonicotinoids that impairs the development of honey bee larvae.
Wessler and Gr?newald were able to directly demonstrate that neonicotinoids reduce the acetylcholine content of the larval food produced by nurse bees. Acetylcholine is a signaling molecule produced in the microchannels of the royal jelly gland of nurse bees. Comparable to neonicotinoids, it stimulates the nicotinic acetylcholine receptors that are also present in this gland.
"In lab tests we artificially removed acetylcholine from the larval food and the result was that bee larvae fed with this died earlier than bee larvae that received food containing acetylcholine," explained Wessler. In order to examine the effect of neonicotinoids on the acetylcholine content in the jelly in more detail, bee colonies were exposed to various concentrations of neonicotinoids in flight tunnels (clothianidin: 1, 10 and 100 μg/kg glucose solution; thiacloprid 200 and 8800 μg/kg). "This exposure led to a reduction in the acetylcholine content of the jelly. Thus we were able to demonstrate that the field-relevant dose of the neonicotinoid agent thiacloprid (200 μg/kg) significantly reduces acetylcholine content by 50 percent. On exposure to higher doses, we were even able to verify that acetylcholine content can be reduced by 75 percent. Exposure of the bees with the higher doses results in serious damage to the microchannels and secretory cells of the jelly gland," emphasized Professor Ignatz Wessler. "Our research results thus confirm that the neonicotinoids can jeopardize the normal development of honey bee larvae."
The EU came to a similar conclusion back in December 2013 and imposed temporary restrictions on the use of three neonicotinoids, i.e., clothianidin, imidacloprid, and thiamethoxam. It had already been reported in several scientific publications that high but not lethal doses of various neonicotinoids could be associated with the falls in the populations of wild bees, bumblebees, and queen bees. Also reported were abnormalities in breeding activity and impaired flight orientation in the case of honeybees. However, at the time there were critics of these reports who pointed out that, among other things, the researchers had used high, non-field-relevant doses of neonicotinoids and had carried out their experiments under artificial laboratory conditions. Moreover, the proponents of the use of neonicotinoids cited other possible causes of bee mortality, for example, the proliferation of the varroa mite and other pathogens.

We were able to requeen a laying worker hive by placing a mated queen into a push in cage. We did not shake out the hive. After 4 days the workers had burrowed under and we're taking care of her. We also used this method to requeen a hive where the queen didn't return from her mating flight. I highly recommend it, as the queen can start laying and emit her pheromones prior to her release and I believe has a higher rate of acceptance.

FARMING & COUNTRY LIFE / Re: Water pump questions for orchard
« Last post by jvalentour on June 27, 2016, 01:06:01 PM »
I wanted to follow up on this topic.
I have been researching methods to water my orchard and found this on youtube,  
I'd like to know if anyone has tried something like this and how good the results were if they did.

FARMING & COUNTRY LIFE / Horse manure in the garden
« Last post by jvalentour on June 27, 2016, 12:59:22 PM »
I picked up half a bucket load (500lbs) of horse manure from my neighbor yesterday.  It was entirely black with some weeds growing on top.  She had a green pile on the other side of the barn and says she turns the piles routinely.
Can I put the black manure directly into my garden to amend the soil or do I need to mix it first with soil then add to garden?
