Abstract
Seasonal flight activity of the scolytid, Scolytus amygdali was
studied by using trap logs on apricot trees at Fayoum Governorate,
during the two seasons 2002 and 2003. It was noticed that in 2002
year, the first occurrence of beetles was around mid March, where the
mean number of trapped beetles was (1 beetle/trap) at daily mean
temperature 19.8oC and 62% R.H. The beetles had four peaks, the
first peak was (4 beetles/trap) in mid June, the 2nd peak was (7
beetles/trap) in late July, the 3rd peak was (5.8 beetles/trap) in mid
September and the 4th peak was (9.4 beetles/trap) in mid November.
In 2003 year, the beetles appeared in late March by (1.4
beetles/trap) at 17.6oC and 58% R.H. The beetles had three peaks, the
1st peak was (1.8 beetles/trap) in late May, the 2nd peak was (4.4
beetles/trap) in late July and the 3rd peak was (10.4 beetles/trap) in
mid November.
Simple correlation between temperature and seasonal flight
activity was highly significant while it was insignificant between
relative humidily and seasonal flight activity during the two seasons
2002 and 2003 years.
