دراسات على المكافحة الميكانيكية لخنفساء قلف أشجار الفستق الحلبي في سورية Hylesinus vestitus M. و R. (Coleoptera : Scolytidae)‎

الملخص EN

Twelve experiments were conducted in two regions of Syria (Al-Muselmiya/Aleppo and Morek/ Hama) to study the pistachio bark beetle, Hylesinus vestitus M.&R., response to detached pistachio branches placed at different sites in relation to the pistachio parent tree, as mechanical control method for H.

vestitus.

The experiments were carried out monthly from December 1995 until November 1996 to study the effect of branch location on attracting the H.

vestitus adults.

Results showed that the scolytid beetle was highly attracted to branches located on the middle-periphery of the tree canopy in northern and eastern sites during May in Al-Muselmiya / Aleppo region.

This attractiveness was high during April, May, October and November, to the branches located inside the tree canopy and against the tree main trunk in Morek/Hama region.

At the end of each month,the dry branches should be collected and burned.

Results indicated that mechanical control was sufficient enough to control the pest.
