Economic effect of the citrus red mite (Acari: Tetranychidae) on southern California coastal lemons



Economic effect of the citrus red mite (Acari: Tetranychidae) on southern California coastal lemons



Journal of Economic Entomology 85(5): 1926-1932



In a 2-yr study, we found no significant relationship between the variation in density and duration of citrus red mite, Panonychus citri (McGregor), populations peaking at > 19 adult females per leaf and variation in total yield, size, or grade of lemon fruit. No effects of high mite populations in the first year were evident upon crop yield, grade, or size in the second year. The conventional treatment threshold for P. citri on lemon has been two adult female mites per leaf. These data do not support the premise that growers who observe that threshold are achieving an economic return.
