Abstract: ln the paper ,the effects of atmospheric phenolpolluted mulberry leaf on the growth and development of silk-worm Bombyx moir larvae were studied through simulatedstatic fumigation and natural investigation for polluted mul-berry leaf. The resuIts show that high level atmospheric phe-nol is toxic directly to silkworm Bombyx moir larvae when it isdiffused intermittently into a silkworm rearing room;low levelatmospheric phenol is toxic indirectly to the larvae throughlong term accumulation of phemol in the mulberry leaf. Whilebeing suffered fot the above,the lightly poisoned larvae willshow the sign of poor appetite,disorderly growth and develop-ment of larvae population,grey skin,and decrease in its bodyweight and reduction in mainly economic characteristics, andseriously poisoned larvae will die.

Key words: atmospheric phenol, pollution, silkworm, mulberry leaf, poison, toxicity
