AbstractThe response of larvae and adults of Tenebroides mauritanicus (L.) to methyl bromide at reduced pressures is complex. Four zones of differing susceptibility were found : (1) at 15–30 mm. Hg pressure high mortalities were due more to desiccation than the action of the fumigant; (2) at 30–50 mm. low mortalities coincided with loss of visible activity; (3) at 50–175 mm. increased activity and high mortalities occurred; (4) from 175 mm. to atmospheric pressure activity was normal and mortalities declined. In zones (2) to (4) the responses were independent of humidity. Larvae of Tenebrio molitor L. gave responses similar to those in zones (2), (3) and (4) but at different pressure ranges.
