    Effects of Tanacetum cadmeum ssp. orientale (Compositae)’ EtOAc extract fractions on feeding behaviour of Spodoptera littoralis (Lepidoptera: Noctuidae)
    (Uludağ Üniversitesi, 2009) Susurluk, Hilal; Gürkan, Mehmet Oktay
    The antifeedant activity of Tanacetum cadmeum ssp. orientale (Compositae) against third instars larvae of Spodoptera littoralis Boisd. (Lep: Noctuidae) was evaluated using lettuce leaf disk bioassay. In the experiments, ethyl acetate (EtOAc) extract fractions of aerial parts of T. cadmeum ssp. orientale showed limited antifeedant activity with 24 h values of 17.64, 23.62, 6.97, 5.69 and 7.8% for fractions 1, 2+3, 4, 5 and 7, respectively. Any fraction did not deter feeding by the larvae. Similarly, no statistical differences were observed on body weight between the treated and control larvae after the experiment. In two cases, there was no significant decrease in growth with the shortterm dipping of the fractions to the lettuce disks.

    The impact of technological changes on small and medium enterprises (SMEs) in Turkish agri-food industry
    (Uludağ Üniversitesi, 2009) Parseker, Zeynep; Çetin, Bahattin; Uludağ Üniversitesi/Ziraat Fakültesi/Tarım Ekonomisi Bölümü.
    Food industry, as being one of the most important manufacturing industries, assists the nation to maintain a steady supply of food products. Turkish agri-food industry displayed a significant growth performance in the last few years. This study clarifies some factors influencing the growth of Turkish agri-food industry with the aim of identifying some technological changes and their impact within small-medium food enterprises in the last ten years. Information about these technological changes in Turkish food industry was realized through questionnaires and interviews. Some technological changes were determined as enlarged capacity of utilization and market share, application of Information and Communication Technologies (ICT), expansion of production lines, use of new packaging systems and participation of the work force in process improvement. It was observed that the number of food enterprises, especially small and medium, has gradually increased over the years and tackled with some problems of processing issues, technological expansion varieties, some technological changes and the factors responsible for technological changes in agrifood industries, and also, proposes how to increase the financial base of the small-medium food enterprises.
