چکیده    Population trends of grape root phylloxera were carried out in highly infested field in husban, madaba district in 2005. mean numbers of eggs and mobile stages, showed a peak in early july. eggs started to appear in late may, and nymphs started to appear in late june. numbers of all stages started to decrease in early august .galls were noticed on examined roots in 2005 as compared with the 2004 season. there were significant differences among pesticide soil treatments for all stages in the two applications. the least mean numbers were found in imidacloprid followed by thiomethoxam with no significant differences. the mean numbers in the above two treatments were significantly different from oxamyl and the control treatments. generally, there were no significant differences between the effects of soil pesticide treatment on different yield parameters. taking into consideration the non significant differences between imidacloprid and thiomethoxam treatments, and the slight difference in the cost of the two insecticides in the present jordanian market, they can be used successfully for controlling grape phylloxera
