[Dynamics of grape berry moth( Lobesia botrana Sch) and mechanism of it's control in the middle region]

-grape berry moth is consider from the main pests that affected the crop of grapes in Syria and cause great economic losses. The experiments were conducted in three sites in the middle region of Syria (Zydal, Abudali and Kfram) during the years 2008-2009 to study the dynamics of this insect by means of pheromone traps. Readings were taken regularly to pheromone traps for the number of males that captured and draw charts by which to identify the possible start of insect activity and to identify the number of generation in various locations. The number of generations of the insect in the 2008 season reached to five generations in Zydal and Abudali sites and to four generations in Kfram site, but in the 2009 season, the number of generations reached to four generations in Zydal and Abudali sites and three generations in Kfram site. Calculated the amount of accumulative temperature necessary to start the activity of the insect and to each generation where: the first generation started when the accumulative temperature was 144 ± 1.4 degree – days and the first peak occurred at 200.5 ± 10.6 degree-days while the second-generation needed 618.5 ± 6.7 daily temperature degree and reached its peak at 834 ± 0.7 ° degree-days, The third generation began when the accumulative temperature was 1231 ± 1.4 degree-days and reached its peak at accumulative temperature 1464 ± 5.7 degree-days , the fourth generation began at 1879.5 ± 6.4 degree-days and reached its peak at accumulative temperature 2088 ± 66.5 degree-days and the fifth generation began when the accumulative temperature was 2651 degree-days and reached its peak when the accumulative temperature was 2710. Grape berry moth needed to 72.3 ± 1.3 degree-days from the beginning of flying to laying eggs. Through a comparison between the two species Alpetamouni and Halawani in terms of its tolerance to the infection grape berry moth, The results show that, Alpetamouni species more tolerance to the infection by butterfly of grapes than Halawani species Pheromone traps showed more effective in control the -grape berry moth during the first and second generation The pesticide Deflubenzuron gave killing percentage of the larvae of -grape berry moth 82.8% and the pesticide Chlorpyrifos48%w/v gave killing percentage reached to 93.9% .
