My camera endoscope ‘Potensic’ arrived by post which enabled me to inspect the inside of the hive Iris without opening it. It comes with a 5 metres flexible tube that can be bent and pushed through the hive entrance. It has a powerful light whose intensity can be adjusted easily by hand. The camera was easy to use and quite effective. It can be joined to a laptop or a smartphone to take still photos or videos. I took a couple of pictures. Sadly, the space between the middle frames looked empty.
The next day as it was sunny and the temperature was hovering around 16 degrees C (60 F), we decided to open up Iris. I was saddened to see just three or four bees inside. The outside frames were full of sealed honey, but no bees.
There was no doubt that they eventually succumbed to the attack by the Asian hornets. There were a few dead bees in the bottom of the hive, plus two dead hornet that had obviously been killed by the brave bees.
The other four hives were still busy, but despite the fact that December has arrived and the night temperatures have been for several nights around zero C, the Asian hornets had not stopped attacking the hives. Amelia and I had searched the countryside around us during our walks but had not found any hornet nests. But our friend Patricia told us a couple of nights ago that on cycling around she had seen a nest. So off we went looking out for it.
There it was just over a kilometre from our house. A nest at a height of some thirty metres from the ground. Now that the trees had lost their leaves the nest was quite visible. I could see the hornets coming and going.
It is important to note that unlike summer bees who live only 6 to 8 weeks, the winter bees live 3 to 5 months while the queen will be laying a very reduced number of eggs. Therefore any attack on winter bees will deplete the colony more rapidly and as we found will be quite disasterous. The other issue we have noted is that there is a misconception that by the end of October, the Asian hornets are all dead and any young queen is hidden in a hollow of a building or a tree until next Spring, when she creates a new colony. We learnt to our horror that even the first week of December, they were attacking the bees.
After our walk in the country, we went over to see our neighbours Annie and Yvon. He is the master of the hunt around here. I showed him the photo and he agreed to come over in the morning with me and do what he could. The next day we went to the site. At that height, it is almost impossible to destroy the nest, but Yvon fired four shots in the middle of the nest, making a few large holes in it. The idea being that the cold will do more damage and the birds will start attacking the nest, thus hastening its demose. Firing into their nest is considered by many to be dangerous, ineffective and certainly should not be attempted in the summer time.
You can see one hornet near the top right hand side, and the nest entrance underneath where the hornets enter and leave. It was a desperate attempt at a desperate situation.
This week the daytime temperatures have really climbed and Amelia and I have managed to have out lunch out in the garden. She even shed her fleece!
The other four hives have been showing a great deal of activity, as you can see in this short video clip.
We felt sorry for the bees that were crowding around the entrance reducer of their hives. They were busy bringing in pollen and naturally nectar.
Amelia felt really sorry for the girls and she asked me to take off the entrance reducer of Viollet, since we have not seen any hornets in the last couple of days. Amelia has always had a soft spot for Viollet.
Some of the bees had huge sacs of pollen. I can assume that although it was sixth of December, the hives still had brood.
We are fotunate that throughout winter there are still enough flowers for the girls to visit and bring in the nectar and pollen. Gorse is a favourite at the moment, the photograph below was taken on the 7 December 2016.
Meanwhile. Viollet had finished her 2.5 Kilogram bag of fondant, so we replaced it at the same time as removing her entrance reducer.
One final observation. When we returned from the UK in early November, we were devastated to see that despite the warm sunny days, the bees were mostly stuck inside their hives and reluctant to come out to face the hornet attack. Panic and stress is as bad for the bees as it is for us. So, although we sadly lost Iris, we are so glad that now the other four hives appear to be strong and all of them flying in and out in great numbers and are bringing in pollen. We hope that the bees and all of us will have a good end to this year, or as the French say: ‘Une bonne fin d’année’. An early Merry Christmas to everyone. – Kourosh
