My feeders are described as the rapid English type by Thorne's. They are very sturdy white plastic with a central dome which sits on the hole on the crown board. The dome is covered by a transparent cup which allow the feeding bees to be observed. Each feeder holds about 6 liters of solution.
The 9 kg sugar is given over a period of about 5 days in three lots: 4kg, 3 kg, and finally 2 kg. These quantities are dissolved respectively in 2520 ml , 1890 ml , and 1260 ml warm water. If the water used is about 1/3 boiling and 2/3 cold water the final temperature is about 30 °C. This warm syrup is readily welcomed by the bees. The first lot is given to be bees late in the evening otherwise the bees may go looking around the apiary for this new source of nectar; this could encourage robbing.
It is remarkable how quickly this syrup is taken down and stored. The feeding is usually over in 5 days. The bees will readily clean up the last remaining syrup in the feeder if the cup is removed.
Formic acid treatment for varroa
After feeding the colonies are treated for varroa with formic acid.
The method is described under
(Varroa 2) and some results shown in
(Varroa 3)
Requeening
After the varroa treatment any requeening can conveniently takes place at this time
(see Requeening.)
The Queen and egg laying
The rate at which the queen lays her eggs decreases rapidly at this time. So the bees spend a shorter time on brood rearing and put more energy in preparing for winter. The brood frames are now filled with winter stores. This characteristic of the black bee gives them an advantage in that all pollen and nectar is stored. The lack of brood at this time can be somewhat deceptive for the inexperienced beekeeper in so far it might be concluded that the colony is queenless. This lack of brood, however, triggers the bees in their transformation to the winter state.
Pollen and Nectar and the Winter Worker
In these three months the bees bring in copious amounts of pollen in preparation for winter. Nearly all of this pollen is eaten by the bees by October and stored in their bodies as fats and protein. Winter bees so produced are physiologically different to the summer bee; so that by springtime they are still capable of looking after the new brood i.e. acting as nurse bees.
To be more explicit the summer worker bee from emerging as a grub to leaving the hive 13 days later as a forager goes through a series of hive tasks. The winter worker on the other hand has the job of seeing the colony through the long cold winter at the end of which it is able to multitask i.e. take on anyone of the hive tasks.
Surplus pollen at this time is stored during the winter in the comb and covered over with honey before each cell is capped; the honey preventing the pollen from going moldy. This pollen is essential being used in the spring to feed the new brood.
The nectar from the ivy being especially rich is eagerly sought out by the bees in October; the pollen is a bright yellow.
