FIRST REPORT Tuberculatus kuricola IN
CONTINENTAL EUROPE In October 2000 a new aphid was detected on chestnut, Tuberculatus (Nippocallis) kuricola, native to Japan, Korea and Continental China, that affects not only chestnut, but also Quercus spp. So far, it was only detected outside its area of origin, in Madeira Island. Since it was first detected in Pontevedra, more specifically on a Castanea x hybrida stand in Moaña municipality, where sooty mould and early defoliation was observed. Later surveys revealed its presence in more municipalities in the province, both on chestnut and oak, but showing no symptoms. |
