Post-fumigation productivity ofTrogoderma granariumEverts (Coleoptera: Dermestidae)

Abstract

AbstractThe productivity of adults ofTrogoderma granariumEverts was reduced following fumigation of the larvae with high dosages of carbon tetrachloride, ethylene dibromide or phosphine. Carbon dioxide, ethylene oxide, methyl bromide, methyl iodide and trichloroethylene had little influence on the productivity. From 0 to 23 % of surviving larvae diapaused compared with 3 % of untreated ones.
