And yet, the following suggests that this trait has not been enhanced in Australia bees.
my comments...
First you would need to know the original level of hygienic behavior and what might have been the natural or background level of hygienic to determine if any success or progress had been made. Secondly if there is no or little economic incentive to encourage folks to select for this characteristic then most folks will not place much effort into any ultimate and/or long term goal.
