B-biotype Bemisia tabaci have documented very strong ability on host utility and resulted in quite wide host-range, which was regarded probably due to effective detoxified enzymes system including varied enzyme type, and carboxylesterase (CarE) might be considerable among them. In this case, the carboxylesterase activity of B-type whitefly after 48 h host transferring were tested on 56 plant species. The results indicated that OD values of CarE varied significantly, and 3.04 times difference between lowest and highest record. It was as expected that the gradient of OD value showed gradual and smooth, and host plants showed little obvious relationship between species and enzyme activity. However, data indicated that OD values of B-type whitefly from 56 plants closed to normal distribution, which might imply the exist of CarE mean activity mean and still not clear about mechanism and significance. This conclusion need more evidence to extend on other detoxified enzymes.
Keywords:B-biotype Bemisa babaci; Carboxylesterase; host plant
