Description
APMoV belongs to the Comovirus genus, members of which are typically beetletransmitted. An isolate of APMoV from Capsicum was shown to be transmitted byDiabrotica balteata and the virus has been experimentally transmitted by D. viridula. Diabrotica spp. are prevalent in regions where the virus is found. APMoV is also readily transmitted by contact between plants but is not transmitted by true seed. Three serologically related but distinguishable strains have been identified: the type strain (C- and M-isolates) and strains H and B. APMoV causes mosaic and mottle symptoms in most Peruvian potato cultivars. Sensitive cultivars may react with initial systemic top necrosis, stunting and leaf deformations. Under cool conditions, plants may develop yellow spotting, blotching or more generalized yellowing on leaves
