دراسة العلاقة بين قطر ساق شجرة التين و نسبة الإصابة بحفار ساق التين الكبير Batocera rufomaculata

الملخص EN

The fig stem borer Batocera rufomaculata (DEGEER, 1775) is the most serious pest on fig trees at the coastal area in Syria.

A field study was conducted in five locations to study the correlation between trunk diameter and natural infestation with the pest.

Inspected trees were divided to five groups according to the trunk diameter.

The findings showed that the trees in the groups with stem diameter less than 10cm were free of infestation.

The insect attacked trees in the other groups with stems of more than 10cm diameter and infestation level increased with radial growth of the tree.

The results indicated that the fig stem borer B.

rufomaculata preferred the fig trees with large stem diameter for attack and oviposition and successful development.
