The aim of this study was to develop a method for automated discrimination of three honeybee subspecies used for breeding in Poland: A. mellifera carnica, A. m. caucasica and A. m. mellifera. The method developed exploits characteristic venation of forewings. Samples of bees were collected from 1042 bee colonies of the three subspecies. From each of the colonies 20 right forewings were dissecte...
As a part of ongoing cytogenetic studies on the jewel-beetles (Buprestidae, Coleoptera) of Armenia, the male karyotypes and meiosis of nine species (5 genera, 4 tribes, 2 subfamilies) are described, figured and discussed. In Ovalisia nadezhdae Sem., Sphenoptera artemisiae Reitt., Coraebus rubi L., C. sinuatus Creutz., Meliboeus caucasicus Reitt., Agrilus angustulus Ill. Men., A. obscuricollis K...
Elm leaf beetle, Xanthogaleruca luteola (Müller), life and fertility tables were investigated under laboratory conditions (25±2°C, 70±5%R.H. and 16L: 8D), on Ulmus carpinifolia, U.c.var.umbraculifera, U. glabra var. pendula and Celtis caucasica, in spring and summer. Since the experiments were conducted under controlled conditions, feeding on hosts with different nutritional qualities was consi...
Bu çalışmada, ıhlamur (Tilia rubra subsp. caucasica) çiçek ektraktı indirgeyici ve kaplayıcı ajan olarak kullanılarak mikrodalga ile gümüş nanopartiküller (AgNP’ler) sentezlenmiştir. AgNP’lerin optimum üretim miktarını elde etmeyi amaçlayan dört farklı sentez değişkeninin birleşik etkisini araştırmak için Tepki Yüzey Metodolojisinin Yüz Merkezli Merkezi Kompozit Tasarımı kullanıldı. Araştırılan...
