Abstract

Spiral gall aphid is considered as an important pest of black POPLAR, P. nigra in Iran. Activity of the pest deforms leaves petiole to spiral shape gall. Consequently, early defoliation of infested trees occurs in mid summer. In 2000- 2001, ten Populus nigra CLONES already planted in randomized complete block design (5 and 6 years olds), were subjected to sampling procedures. In each experimental plot from 25 existing POPLAR trees, nine which placed in the middle of plots were studied. In mid summer, four branches of every POPLAR tree (120 centimetres) were cut and number of aphid galls was recorded. The branches were selected from four geographical directions of trees. All branches were selected from the same height of POPLAR trees. Analysis of variance of obtained data revealed a significant difference (a=5%) between tested CLONES. While, no significant difference was observed among the geographical directions of trees. The results also showed that CLONES Populus nigra 56/52 and Populus nigra 62/154 had the maximum and minimum pest densities, respectively. Furthermore, natural enemies of this pest in ZANJAN climate are parasitoid wasps Aphelinus flaviventris and bug predator Anthocoris minki.
