Description
Ruotong Shen and co-authors report a 2026 study of how mild carbon dioxide levels affect the larger black flour beetle, a stored grain pest spreading worldwide. Grain bulks naturally reach carbon dioxide levels between a quarter and four percent, and such levels might support fumigation or controlled atmosphere treatments. Beetles were raised at five gas concentrations and two temperatures, then compared with controls breathing ordinary air on survival, development, egg laying, and life table measures.
Carbon dioxide in the tested range changed survival and development at both temperatures. Once levels passed a quarter or half percent, generation time, survival rate, egg laying, and population growth measures all shifted significantly. The authors argue these biological responses matter when setting exposure times for gas based pest control. Their results add a reference point for managing this beetle in modern monitored grain stores.
