  • Abstract By using chemical pesticides, the harmful of pests on crops was well controlled and the loss of agricultural economy was decreased. However massive use of chemical pesticides caused environmental damage, unbalance of ecosystem and threatened human health. Recently, biological control agents were developed, which consisted of bacteria, fungi, viruses, protozoa and microbial metabolites, having ability to kill pests and germs or to regulate plant growth. In the present work crab shells were treated with acid and alkali to remove calcium salts and proteins. After being dissolved in concentrated hydrochloric acid and then diluted into ice water, suspended chitin solids were formed. When the fungus was cultured on chitin containing agar medium, the formation of clear zone revealed that chitinase had been produced. The submerged fungal culture can be served as biological control agent, killing pests and plant pathogenic fungi.
