The conical flask method was used to determine the biological activity of allylisothiocyanate against four storage pests such as corn weevils Sitophilus zeamais( Motschulsky) , Rhizopertha dominica(Fabricius) ,Tribolium castaneum(Herbst) , Liposcelis entomophilus Enderlein.
When the concentration was 0.125-3μg/ml, it had different degrees of biological activity against the four storage pests. Among them, the strongest inhibitory effect was on the grain borer and book lice, whose LC50 were 0.41μg/ml and 0.33μg/ml respectively. When the concentration was 3μg/ml, the fumigation effect on the four storage pests was close to 100%.
Allylisothiocyanate is used in lower dosage than the currently used fumigant aluminum phosphide, is safe for the environment, and has potential use value.
