This study identifies a conserved cold stress syndrome in insects, showing that hyperkalemia and ion homeostasis failure define chill tolerance across species and stress conditions.

This study uses thermal death time models to analyze cold stress resistance across Drosophila species, finding that cold tolerance decreases with colder winter environments and that TDT curves provide predictive insights into insect cold resistance.

This study uses gas exchange measurements to assess growth, energy use, and body composition of black soldier fly larvae on diets with different protein-to-carbohydrate ratios.

This study examines how imbalanced essential amino acid diets affect growth, metabolism, and energy use in black soldier fly larvae, finding reduced growth and increased metabolic costs.

This study examines how Na+/K+-ATPase activity maintains muscle membrane potential in Drosophila species under different temperatures, finding that cold-tolerant species retain this electrogenic effect while sensitive species lose it.

This study shows that endogenous circannual cycles drive seasonal cold hardening in temperate ants, independent of environmental cues, by modulating cold tolerance and metabolomic profiles.
