POPULATION DENSITY OF THE PEACH FRUIT FLY BACTROCERA ZONATA (DIPTERA: TEPHRITIDAE) AND SOME PLANT SPECIES THAT INFECT IT

This study was conducted in the city of Baghdad in three locations, two locations were in Al-Jadiriya and the third location in the region of Sadr Al-Kanat during the 2017-2018 season. The insect began to appear in the first and second location in Al-Jadiriya on the 1st of April and recorded its first appearance in the third location in Sadr Al-Kanat during the last week of March. The number of insects was characterized by fluctuation between the rise and fall during the months of the year and the highest density of the insect during the autumn months (October and November) and the presence of a few numbers during the winter months (January and February) and the insect has 6-7 generations of the year based on the density of the insect and the length of the generation and its association with the plant family and Femilure attractant was not effective in catching the insect. The rate of ripening of fruits was consistent with fruit maturity. Apricots were infected by 16.6% in June and 46.6% in July, peach infected by June and July by 21.3% and 25.3% respectively, yellow Figs during July and August by 15.3% and 20% respectively, mango during August and September by 18.3% and 36.6% respectively, mandarin during October and November with 21.3% and 26.6% respectively, oranges during November and December by 17.9% and 20% respectively, and sour orange at December by 3.3%.
