[Objectives]   To determine the preferences of adult Bradysia odoriphaga for different organic fertilizers and thereby provide a scientific basis for choosing fertilizers to control this pest. [Methods]   Preferences of adult B. odoriphaga for different organic fertilizers were assessed in indoor controlled experiments, Y-tube experiments and field experiments. [Results]  The relative preference for different organic fertilizers was as follows: soybean meal matrix > animal manure > poultry manure > sesame oil residue > quail manure > plant ash. There was a positive preference for soybean meal matrix and animal manure but a negative preference for quail manure, composted quail manure and plant ash. Moreover, oviposition and numbers of larvae produced on the latter three fertilizers were significantly less than on the control. [Conclusion]  Using composted poultry manure and plant ash as fertilizers when adult B. odoriphaga are present could not only improve the efficacy of controlling this pest but also increase crop yield.
