Abstract:

Objective　To explore the on-site fly control effects of a new biological agent, Echo, in animal farms. Methods　Echo, chlorbenzuron, pyriproxyfen, a mixture of Echo with chlorbenzuron, and a blank control were sprayed at the same concentration onto feces in a laboratory simulation and in the field. Results　After treatment with Echo for 12 days, compared to the control group, the emergence rate of flies from the feces exposed at 24 h, 48 h and 72 h, decreased by 96.2%, 64.4% and 86.7%, respectively. After treatment with Echo and the mixture of Echo and chlorbenzuron for 7 days and 12 days in the field, the density of fly larvae decreased by 56.2% and 65.5%, respectively. After treatment with Echo for 12 days, fly density decreased by 71.2% compared to the control. After treatment with the Echo and chlorbenzuron mixture for 12 days, fly density decreased by 55.2% compared to the control. Fly density also decreased by 74.5% after treatment with Echo for 6 h in the field. Conclusion　The Results　show that Echo was effective in deodorization, inhibition of fly breeding and reduction of fly density.
