The noninclusion virus of Panonychus citri (McGregor) distributed in orange trees by spraying distilled aqueous suspensions of triturated diseased mites. A 0,01% concentration produced as high an incidence of disease as a 0.1% concentration, and applications after sundown were not more effective than applications during a sunny day. The application of suspensions of diseased mites buffered at pH 6.0 produced nearly twice the incidence of infection as a comparable unbuffered suspension. Release of infected mites obtained in the field from an area known to harbor an active epizootic into an apparently virus-free grove produced more than twice the incidence of infection as the release of laboratory-reared and infected mites. Epizootics of the disease developed in all experimental groves.
