Effects of a High Vacuum on Insect Mortality1

Abstract
The Madeira cockroach, Leucophaea maderae (F.); the Mexican bean beetle, Epilachna varivestis Mulsant; the house fly, Musca domestica L.; the confused flour beetle, Tribolium confusum Jacquelin duVal; and the Japanese beetle, Popillia japonica Newman, were exposed to pressures of 0.05 to 0.03 mm of mercury for periods of 2 to 64 min. A high mortality occurred for all species at the 64-min exposure level. Weight loss ranged from 14% to 47%. A drop in internal temperature from 26°C to about 10°C was observed in the Madeira cockroach and the Japanese beetle during the 64-min exposure period.
