Abstract
The hygienic behavior of honeybees (Apis mellífera) is a mechanism highly influenced by genetic effects that confers resistance against diseases and parasites. The objective of this study was to determine whether climatic, regional and brood quantity influences are related to hygienic behavior in beehives in the state of Jalisco, Mexico. A total of 142 colonies were evaluated by freezing pupae with liquid nitrogen in two climatic zones (mountain and valley). Colonies located in the municipalities of the low zone removed significantly more frozen brood than the colonies located in the municipalities of the higher zone (p 80%). This degree of cleanliness is acceptable for initiating selective breeding projects for highly hygienic bees to improve colony health, which would benefit the beekeeping industry.
