Hyalopterus pruni (Geoffr.) appears to be the most important pest of peach and apricot in Egypt. Its bionomics were studied in the field at Dokki in 1965-66 on its alternative food-plant Phragmites communis. There were 42 generations during the year. Development was most rapid (six days for a complete generation) in June-July at an average of about 26-28 deg C and 45-63% R.H.) and slowest (15 days for a complete generation) in January at about 12 deg C and 64% R.H.
