Rhopalosiphum rufiabdominale: first records from winter host plants in Europe
Bulletin of Insectology 68 (1), 73-81
Abstract: Aphid species Rhopalosiphum rufiabdominale (Sasaki) has been originally described from Japan where it is heteroecious holocyclic alternating between Prunus spp. and the underground parts of numerous species of herbaceous plants. Current knowledge is that it obligate alternation between winter and summer hosts in the East Asian region only, whilst populations reproducing by means of obligate parthenogenesis are distributed in warmer climates and in glasshouses worldwide. In 2013, two samples of Rhopalosiphum were collected in Bagnolo Mella of Brescia province in northern Italy from Prunus armeniaca (apricot) and Prunus domestica (common plum). The attribution of these two samples to R. rufiabdominale was confirmed both morphologically and by the application of two molecular markers, partial sequences of mitochondrial COI and nuclear EF-1alpha genes. This was the first record of R. rufiabdominale from its winter hosts Prunus spp. outside the East Asian region. Once holocyclic populations may exist in southern Europe, these aphids can inhabit the entire temperate region worldwide because they can thrive harsh winter conditions as overwintering egg.
