The Asian citrus psyllid, Diaphorina citri Kuwayama, vectors the bacterium Candidatus Liberibacter asiaticus, causal agent of Huanglongbing, one of the most serious diseases of citrus in the world. The vector and disease are now present in Mexico and threaten the citrus industry. In the state of Sonora, the citrus industry is important economically and socially. Until now, Huanglongbing has not been reported in the state, but the insect vector has been present since 2006. In southwestern Sonora, an area-wide program was established to manage the Asian citrus psyllid and reduce risk of Huanglongbing. The program requires efficient and efficacious sampling for control decisions. A study comparing yellow sticky card trap and stem-tap sampling methods for monitoring adults was used to select the best method for the Asian citrus psyllid area-wide program in the region. Data showed both methods were efficacious for sampling abundance of Asian citrus psyllids, but may be used for different objectives; yellow sticky traps would be better for extensive monitoring while stem-tap sampling is more precise for use in making control decisions.
