Clinical severity is highly variable in the different subtypes of MMP. Previously, the term cicatricial pemphigoid was used for MMP. Progressive s

Colony Defense,atever the race, large, populous colonies are more aggressive and effective at nest defense than smaller ones. Finally, in any event, there is a high degree of unpredictability that has thus far frustrated a clear-cut ethological analysis.

Also, the presence of modifying genes holds great significance for populations because they may readily respond to selective pressures and thus provide a population with the flexibility needed to respond to changes in the environment (Wri

Swarming, Migration and Absconding,The origins of these traits can be ascribed to differences in climate and predation pressure (Seeley 1985). The honeybee races of Europe have only brief periods favourable for swarming and the establishment of new colonies. Their massive food reserves are conserved and sustain the colonies over wint
