Abstract
Bactericera cockerelli (Šulc) is a common pest of solanaceous crops largely known for vectoring "psyllid yellows" in potatoes. In recent years, however, this pest has attracted considerable attention for vectoring Zebra Chip, a devastating bacterial disease that was first reported in the United States in 2004 and has spread across the southern and northwestern states, causing significant economic losses to potato growers and the industry. Management of the disease is mainly achieved by reducing the psyllid population using insecticides, including pyrethroids and neonicotinoids; however, new insecticides with different modes of action are needed to avoid the acquisition of resistance. In the current study, the immediate and residual effects of conventional and new materials were tested under greenhouse conditions against adults and nymphs. Cyantraniliprole at a high rate and spinetoram showed the highest immediate and residual activity against adults, whereas cyantraniliprole and oxamyl (low and high rates) were effective against nymphs, with no differences between rates. Soil applications of cyantraniliprole, oxamyl, and imidacloprid were still toxic to adults and nymphs 7 and 14 d after treatment. Also, cyantraniliprole and tolfenpyrad were detrimental to psyllid reproduction. The incorporation of new chemistry in rotation programs may provide a useful management tool against this pest.
