Abstract

Abstract: Variation of bacterial communities in the sediment was studied after being treated by preparation of Bacillus.The results showed that the probiotic Bacillus changed bacterial species composition of sediment and increased the number of aerobic bacteria.Shannon-Wiener index was used to analyze the species diversity,it found that diversity index(H),abundance(D) and evenness(J) of three ponds were lower at prophase,all rose at metaphase、anaphase and telophase.However,compared with control pood,bacteria dominanted in experiment ponds changed,the number of Flavobacterium and Cytophaga increased,while the number of Vibrio and Photobacterium reduced relatively,and prawn survival rate,mean weight at harvest and production were improved.

Key words: Liriomyza sativae, Secondary substance, Petroleum spray oil, Parasitoids, Population control
