Worker bumble bees help determine which baby bee will become queen

Phys · · 823 words · By Katie Bohn

Researchers at Penn State have discovered that worker bumble bees influence whether larvae become queens by passing juvenile hormone through the food they provide. The study indicates that this process is decentralized and linked to the colony's aging process, rather than a top-down hierarchy.

“The study, published in the journal Insect Biochemistry and Molecular Biology, explored why some bumble bee larvae become workers and others become queens, despite coming from the same eggs.”
SINGLE SOURCE
The claim is explicitly stated in the Mirage News article. While other search results discuss bumblebees generally, only this one source confirms the specific study in 'Insect Biochemistry and Molecular Biology' regarding larvae caste determination.
