Investigations on gallery patterns of the Almond bark beetle (Scolytus amygdali Guerin-Méneville 1847) (Coleoptera, Curculionidae) in Tunisia

Scolytus amygdali Guerin- Méneville, 1847, Tunus'da önemli ekonomik bitkilere zarar yapan bir kabuk böceğidir. Tür; Scolytus mediterraneus gibi meyve ağaçları üzerinde zarar yapan diğer kabuk böceklerine morfolojik olarak benzemektedir. Türlerin ağaçlar üzerinde meydana getirdikleri larva yollarını birbirlerinden ayırt etmek de oldukça güçtür. Bu detaylı çalışma kabuk altındaki böcek hasarı ve galeri sistemleri hakkında daha fazla ayrıntı vermek amacıyla Tunus merkez bölgesinde gerçekleştirmiştir. Zarar görmüş Badem dallarındaki ana ve larva yenik yolları incelenmiş ve ölçülmüştür. Scolytus amygdali galeri sistemlerindeki ölçümler ve yenik şekillerinin ayrıntıları; Tunus'ta meyve ağaçlarına saldıran kabuk böceklerinin teşhisini kolaylaştıracağı düşünülmektedir.

Tunus ta Badem yazıcı böceği (Scolytus amygdali Guerin- Méneville, 1847) (Coleoptera, Curculionidae)'nin galerileri üzerine araştırmalar

The Almond bark beetle Scolytus amygdali Guerin-Meneville, 1847 is a serious beetle that can affect important economic crops in Tunisia. The species is morphologically similar to other bark beetles attacking fruit trees such as Scolytus mediterraneus. The gallery systems of both species are also generally hard to differentiate. A detailed study about gallery systems has carried out in the central region of Tunisia in order to give more details on beetle damage under the bark. Maternal and larval galleries from infested branches of almond were examined and measured. It is hoped that these details of the shape and measurements of the gallery systems of Scolytus amygdali will facilitate the identification of infestations of almond bark beetles attacking fruit trees in Tunisia.
