Type of article: Article

Summary

WHEAT GRAIN INFESTED WITH THE CUCUJID CRYPTOLESTES FERRUGINEUS WAS HELD FOR VARYING NUMBERS OF WEEKS AT TEMPERATURES OF -5, 0, 5, 10 AND 15 DEG C IN SEPARATE TESTS. SURVIVAL OF THE IMMATURE STAGES DECLINED EACH WEEK AT EACH TEMPERATURE. THE LETHAL TIMES LT50 AND LT99 WERE DETERMINED FOR EACH OF THE TEMPERATURES EXCEPT THE LOWEST ONE, FOR WHICH 100% MORTALITY WAS OBSERVED IN 1-2 WEEKS.
