News From Abroad: “Stressed” Bees Cause Colony Collapse?
New research from Queen Mary University of England and Washington University in St. Louis, MO suggests that two to three week old bees have too much pressure. Colonies already stressed by weak hives, low food supply, kill off older bees quickly. This leaves young bees without adequate “in hive” care and forces the young out to forage sooner.
Researchers armed the bees with tracking devices and were able to learn the bees were completing less foraging flights overall and consequently, living shorter lives. This new adaptive behavior is further pulling population numbers down by manipulating the “natural” demographics in the hive caste system.
