Life stage and the environment as effectors of transposable element activity in two bee species

Sarah Signor, George Yocum, Julia Bowsher Published: January, 2022 Abstract Diapause is a complex physiological phenomenon that allows insects to weather stressful environmental conditions. The regulation of diapause is accordingly complex, including signaling pathways that involve both small RNA and mRNA and affect the cell cycle, stress resistance, and developmental timing. Transposable elements, mobile genetic…

Thermal history of alfalfa leafcutting bees affects nesting and diapause incidence

Earls, Kayla, Porter, Monique, Rinehart, Joseph P., and Greenlee, Kendra J. Published: November 26, 2021 Abstract Variable spring temperatures may expose developing insects to sublethal conditions, resulting in long-term consequences. The alfalfa leafcutting bee, Megachile rotundata, overwinters as a prepupa inside a brood cell, resuming development in spring. During these immobile stages of development, bees…
