Abstract
BACKGROUND: The Asian citrus psyllid, Diaphorina citri (Hemiptera: Psyllidae), is the most destructive pest of citrus in Florida. The development of insecticide resistance in several populations of D. citri has been documented. There is an urgent need to develop and integrate novel tools for the successful management of D. citri and also to prevent the development of insecticide resistance. RESULTS: The effects of a relatively newer chemistry, cyantraniliprole, against D. citri were investigated. The contact toxicity of cyantraniliprole was 297-fold higher against D. citri than its primary parasitoid, Tamarixia radiata (Hymenoptera: Eulophidae). D. citri settled and fed less on cyantraniliprole-treated plants than controls at concentrations as low as 0.025 and 0.125 µg AI mL⁻¹ respectively. D. citri egg production, first-instar emergence and adult emergence were significantly reduced on plants treated with 0.25, 0.02 and 0.25 µg AI mL⁻¹ of cyantraniliprole, respectively, when compared with control plants. Under field conditions, foliar and drench treatments with cyantraniliprole (1436.08 g ha⁻¹) reduced numbers of D. citri adults and nymphs, as well as of a secondary pest, citrus leafminer, Phyllocnistis citrella (Lepidoptera: Gracillariidae), more than a standard insecticide. CONCLUSIONS: These results suggest that cyantraniliprole should be a valuable new tool for rotation into D. citri management programs. For insecticide resistance management, cyantraniliprole may be particularly useful for rotation with neonicotinoids. In addition, cyantraniliprole was much less toxic to T. radiata than to D. citri and thus may have less impact on biological control than other currently used broad-spectrum insecticides, such as organophosphates and pyrethroids.
