Message:
Abstract:
Camarotoscena fulgidipennis Loginova is considered as an important sucking pest of poplars in Iran. During 1991-1992, damage rate of C. fulgidipennis was evaluated on 15 native & exotic poplar species and clones in Alborz Research Center of Karaj Experimental species include: Populus trichocarpa Torr., Populus simonii Carr., Populus ciliata Wall, Populus nigra L. and Populus alba L.. A randomized complete block design with 3 replications was applied. Each block included 25 seedlings. Buffers were ignored and 6 seedlings were examined for psyllid damage at 15 day intervals starting in mid-June until late September. In order to sample, damage of leaves percentage were estimated on seedling. A numbering method was applied (0-4) to measure damage rate. Data were analyzed by MSTAT- C software and Duncan test (α=1%) was applied to compare the means. Based on two years results, there was significant difference (α=1%) between poplar species and clones. In 1991, of all poplar clones, P. nigra 42.78, P. nigra 47.3 and P. nigra 56.33 followed by P. nigra 56.32 and P. nigra 42.53 showed high damage. In 1992, mentioned clones and P. trichocarpa placed in one group had the highest damage. Based on the results, there were no damage on P. alba, P. ciliata, as well as the other clones of P. nigra.
