Human association with honeybees is a long one. We have and continue to move bees, beekeeping equipment and the products of bees as we travel. Thus it was not unusual for Brazilian beekeepers to look elsewhere for better adapted bee stock as they

sought to improve beekeeping return in the 1950s. The resulting importation of African bee queens into Brazil would, like our repeated importations of Varroa into countries, prove to be a costly, serious mistake. Africanisation of honeybees in the Americas from Argentina to the south-western USA (with only Chile and a few Caribbean islands as exceptions) has completely changed the culture of raising bees in the Americas. Paradoxically it has also opened new opportunities for rural development using bees.

NEW RESOURCE The Africanised honeybee does represent a ‘new’ resource for rural subsistence farmers campesinos of the Americas. Honeybees are readily available and free as swarms, as bee colonies in trees and caves and for honey hunting. The campesinos are not by tradition keepers of honeybees, traditionally keeping stingless bees. European honeybees seldom
