Isle of Wight Disease in Hive Bees. D7 
Eggs were found in the parent stock (DEP) on 14th June, and the queen 
of the first swarm (DES 1) began to lay on the 15th. 
The queen in the second swarm was long in being mated, and was balled 
by the bees on 28th June, A black virgin queen was introduced on the 30th 
June, and she began to lay in due course. The other two queens were as 
yellow as pure Italians, and the young bees were also light coloured. 
The population of the parent stock was much depleted by the double 
swarming, and further, on 23rd June, foul brood was found to be present. 
This was a variety which attacks the larve before sealing, and attempts were 
made to treat the infected cells with dilute formalin. This treatment was 
successful so far in that the disease appeared to be checked, but unfortunately 
the queen was lost either during the manipulation, or poisoned by the formalin 
vapour. Queen cells were made from the brood in the hive and a black queen 
was produced, which ultimately began to lay. The stock was now very weak 
in numbers but was active in raising brood, in defending the hive against 
robbers, and in carrying pollen. 
Up to 4th September it could not be said that there were any symptoms 
in the apiary of Isle of Wight disease. From the nature of the experiment 
here being recorded, a specially close watch was kept for indications of its 
appearing. Only at one period were suspicions aroused. The month of July 
was very wet and must have been very trying to the bees. On the 25th, a 
few “crawling” bees were seen in front of the parent stock and also the first 
Swarm, as well as in front of another stock of black bees not related to the 
bees of the present experiment. And again, on the 31st, it is recorded that there 
were a few “crawlers,” most in front of the first swarm (DES 1). August was 
also a wet month, but nothing of a suspicious nature was noticed. In spite of 
the very adverse circumstances above narrated, all three stocks remained 
perfectly healthy, and up to this date (20th September) the parent stock, 
which is housed in the presumably infected hive, was fed with honey from this 
hive, and was later given some of the original combs, is healthy and, as far as 
the eye can judge, growing in prosperity. 
On 30th September, a lot of driven bees from which the queen had been 
removed was imported from North Wales and added to the little stock (DEP). 
The bees were fed on sugar syrup boiled with vinegar and were packed down 
for winter. | 
On 14th October, the first fine day since the addition of the Welsh bees, 
large numbers of bees were seen out upon the alighting board. This was 
probably related to robbing, which was being actively attempted at several 
hives in the apiary. 
On the 28th December, a mild day, with a few bees offering to fly, the hive
