The residual property of DDT as influenced by temperature and moisture

, : The residual property of DDT as influenced by temperature and moisture. Journal of Economic Entomology 42(3): 420-423

Screens treated with 5% DDT in kerosene and held at 37[degree] C in moist conditions showed a marked reduction in effectiveness against house flies over a period of 39 mos., while similar screens held at 23[degree] remained highly effective for the same period. Both high temp. (37[degree] C) and high moisture (60 to 75% R. H.) produced a more rapid reduction in toxicity of DDT than low temp. (23[degree] C) and low moisture (25 to 40% R. H.).
