TL;DR: The genome sequence of the honeybee Apis mellifera is reported, suggesting a novel African origin for the species A. melliferA and insights into whether Africanized bees spread throughout the New World via hybridization or displacement.

TL;DR: Overall, gene repertoires suggest that the route to advanced eusociality in bees was mediated by many small changes in many genes and processes, and not by notable expansion or depauperation.

TL;DR: There is no single road map to eusociality; independent evolutionary transitions in sociality have independent genetic underpinnings and these transitions do have similar general features, including an increase in constrained protein evolution accompanied by increases in the potential for gene regulation and decreases in diversity and abundance of transposable elements.

TL;DR: It is shown here that silencing of vitellogenin expression causes a significant increase in JH titer and its putative receptor, which corresponds to a dynamic dose–response.

TL;DR: As reproduction includes a variety of specific behaviors, including migration and diapause, JH has come to function as a master regulator in insect reproduction and the peak of pleiotropy was definitely reached in insects exhibiting facultative polymorphisms.
