摘要: The woolly poplar aphid, Phloeomyzus passerinii (Signoret) (Sternorrhyncha: Aphididae), causes the most damage to poplars in southern Europe and Near East as outbreaks can lead massive mortality mature stands. Previous studies, conducted on cuttings or young trees, showed that resistance varied depending genotype. However, these results did not indicate how aphid populations were affected by tree only partially confirmed field observations. This study investigated effect settlement performance of genotypes belonging Populus × canadensis Moench, interamericana Brockh., nigra L., deltoides Bartram ex Marshall, trichocarpa Torr. & A. Gray Hook. using a single clone. was under three experimental conditions: (i) unrooted cuttings, (ii) potted (iii) trees. rate, larval development fecundity by...
