Abstract:The khapra beetle, Trogoderma grananum Everts, was first found established in California in 1953 and was subsequently detected in Arizona and New .Mexico, as well as in Baja California, Mexico, but has not been found in other states. In connection with the suppression program in progress since 1955, an experimental culture of khapra beetle has been reared in the laboratory under quarantine conditions to develop information as rapidly as possible concerning the biology and control of this insect. Data given here concern food preferences, effect of environmental conditions on the biology of the beetle, and the reaction of starved larvae to low temperatures and fumigation. Results of experiments arc given for contact insecticides as grain protestants. Data are presented on fumigation studies as follows: (1) penetration of methyl bromide into the soil;(2) effect of exposures of 2, 8, 24, and 8 hours and temperatures of 50, 70, and 90. on the control of khapra-beetle larvae by the use of acrylonitrile, ethylene chlorobromide, ethylene dibromide, hydrocyanic acid, and methyl bromide; and (3) fumigation of khapra-beetle larvae at 70. with a 24-hour exposure in the presence of no load and of one-half load of wheat of either 7 or 14% moisture content, using acrylonitrile, ethylene chlorbromide, ethylene dibromide, hydrocyanic acid, and methyl bromide.
