A new small iridescent virus from grubs of Phyllophaga anxia (LeConte) (Col., Scarabaeidae)
View through CrossRef
AbstractPhyllophaga anxia iridescent virus (PaIV) is reported from Phyllophaga anxia (LeConte) grubs in southern Quebec. It is the first naturally‐occurring viral disease of P. anxia and the first record of an iridovirus infection in North American scarabaeid beetles. Although intrahemocoelic injection of 2 to 3 μl of purified PaIV produced a high percentage of grub mortality in the laboratory, PaIV appeared to have little significance as a natural regulator of P. anxia and allied species in the field.ZusammenfassungEin bisher unbekanntes Irideszenz‐Virus aus Larven von Phyllophaga anxia (LeConte) (Col., Scarabaeidae)Die Verfasser berichten über das Auftreten des Phyllophaga anxia Irideszenz‐Virus (PaIV) südlich von Quebec, das aus Larven von Phyllophaga anxia (LeConte) gezogen wurde. Dieses ist die erste natürlich auftretende Viruserkrankung von P. anxia und der erste Bericht einer Irideszenz‐Virose bei nordamerikanischen Scarabaeiden. Bei intracölonaler Injektion von 2 bis 3 μl gereinigtem PaIV starb eine hohe Anzahl von Larven. PaIV scheint aber im Freiland wenig Einfluß als natürlicher Regulator von P. anxia und verwandten Arten zu haben.
