摘要：It has been found that animal feeds like crushed barley, crushed gram and wheat bran can be effectively disinfested by fumigation with 3:1 mixture of ethylene dichloride and carbon tetrachloride at a dosage of 2.5 gallons per 1,000 cuft. The lowest average atmospheric temperatures, at which the fumigation for 48 hours and for 72 hours was found effective, were 28.6 and 24.15 degree celcius respectively. It was also found that the order of susceptibility of the three test insects, viz. Tribolium castaneum Herbst, Trogoderma granerium Everts and Latheticus oryzae Watrh and their various stages varied considerably. in all cases, adults and pupae were found to be more susceptible than larvae.
