> Now want to try some morphometry and if possible fine tune by a couple of parameters.

Studied extensively in Mexico:

These studies were conducted during the first five years of Africanization and demonstrated the usefulness of using wing length as one of the selection criteria in a breeding program. However, in areas that have been Africanized for some time this association of morphology and behavior may break down. For example, a study that looked at bees from multiple beekeeping operations in Venezuela found ! no correlation between morphometric characters and defensive behavior ! (Collins et al. 1994).
