The results of Lycoriella pleuroti Yang et Zhang under natural temperature and controlled humility condition showed,the development temperature of egg,nymphs and pubae was 11.9±0.29℃,8.1±0.59℃and 9.3±1.24℃ respectively,the effective temperature constant was 26.4,145.1,42.1 day-degrees.Under 14.9～25.5℃,the highter of temperature,the shorter was the periods of every worm morphology,the lower of the worm casting off frequency as well as number of adult laying eggs.The egg could not incubate under relatively humility less than 93%,the nymphs and pupae could not survive under relatively humility less than 85%.The relation between relatively humility（RH）and nymphs average life（L）was L=e-1.3419+0.04227RH.The best suitable culture materials were cotton seeds shell and stipe of fruibody.Moreover,the nymph quantity changed with the culture style and culture material differing.
