Entomopathogenic fungi are natural enemies of D. citri adults in Mexico. Natural prevalence (%) of fungi on live adults in central Veracruz (summer) and southern Tamaulipas (fall) were: Hirsutella citriformis (7-35); Isaria fumosorosea (5-15); Lecanicillium (2 in Tamaulipas), and Beauveria (<1). Torrubiella (=Sporothrix) is a hyperparasite of Hirsutella. In inland Tamaulipas only Isaria was found. Entomophthora (<2%), a new report for Diaphorina, was found at Veracruz in October 2012.
