So I've looked through the literature and I found a review article saying all of this and more. It was written by a group of respected physicians from American and French hospitals and it clearly supported the widely held belief that you should drink two to three litres of water a day.
This is a common occurrence to have your brood chamber become honey bound during the main nectar flow. A typical hive body will have a brood cluster in the middle and the outside frames will contain honey. A honey bound hive happens when brood begins to emerge, it is replaced with nectar.
The Africanized honey bee was first introduced to Brazil in the 1950s, in an effort to increase honey production; but, in 1957, 26 swarms accidentally escaped quarantine. Since then, the species has spread throughout South America, and arrived in North America in 1985. Hives were found in south Texas of the United States in 1990.
