No evidence that reproductive bumblebee workers reduce the production of new queens
Article Abstract:
The hypothesis that reproductive activity in bumblebee, Bombus terrestris, workers does not reduce the production of new queens is tested. The findings indicate that there was no significant difference in queen productivity between colonies with reduced or normal levels of egg-laying or aggressive workers.

A test of information use by reproductive bumblebee workers
Article Abstract:
The hypothesis of Bourke and Ratnieks are tested by adding male larvae greater or less than 10 days old to each member of nine pairs of Bombus terrestis. The conclusion states that workers have access to information that would allow taking reproductive decisions enhancing their inclusive fitness.

Social parasitism by male-producing reproductive workers in a eusocial insect
Article Abstract:
Efforts made to examine how eusocial bumble bee produce adult male offspring in unrelated, conspecific colonies is studied. Their faster reproductive capabilities and more aggressiveness than the resident workers are also researched.
