Vrste kukaca koje oštećuju industrijsko drvo u Zapadnoj crnomorskoj regiji u Turskoj

Insect species collected in log depots in Western Black Sea Region of Turkey were identified. The study covered two years, 2015 and 2016, in 21 log depots in seven provinces (Duzce, Bolu, Zonguldak, Bartin, Karabuk, Kastamonu and Sinop). The study area was divided into three sub regions and each sub region was analyzed for insect species, their prevalence and intensities. Overall, four orders, 22 families, 74 genera and 57 species were described in log depots of the study area. Sub region 1 (Düzce-Bolu) showed the highest diversity in terms of insect species and sub region 2 (Zonguldak-Bartin) had the lowest diversity. Dorcus parallelipipedus Linnaeus, 1758 (Coleoptera: Lucanidae) and Rhagium inquisitor Linnaeus, 1758 (Coleoptera: Cerambycidae) were found in all provinces studied. Based on wood species analysis, Scots pine wood had the highest diversity in insect species, followed by fi r, oak and beech. The study also described some important wood-destroying insect species from the families Anobiidae, Buprestidae and Cerambycidae. Buprestis dalmatina (Mannerheim, 1837) (Coleoptera: Buprestidae), Leptura aurulenta (Fabricius, 1792) (Coleoptera: Cerambycidae) and Stictoleptura scutellata (Fabricius, 1781) (Coleoptera: Cerambycidae), all wood-destroying insect species, were identified for the first time in the Western Black Sea Region of Turkey.U sklopu istraživanja identificirane su vrste kukaca koje su prikupljene na stovarištima trupaca u Zapadnoj crnomorskoj regiji u Turskoj. Studija se provodila tijekom dvije godine, 2015. i 2016., na 21 stovarištu u sedam pokrajina (Duzce, Bolu, Zonguldak, Bartin, Karabuk, Kastamonu and Sinop). Područje istraživanja bilo je podijeljeno u tri podregije u kojima su analizirane vrste kukaca, njihova prevalencija i intenzitet. U skladištima trupaca na istraživanom su području ukupno opisana četiri reda, 22 porodice, 74 roda i 57 vrsta kukaca. U podregiji 1. (Düzce-Bolu) primijećena je najveća raznolikost vrsta kukaca, a u podregiji 2. (Zonguldak-Bartin) zabilježena je najmanja raznolikost. U svim istraživanim pokrajinama pronađeni su Dorcus parallelipipedus Linnaeus, 1758 (Coleoptera: Lucanidae) i Rhagium inquisitor Linnaeus, 1758 (Coleoptera: Cerambycidae). Na temelju analize različitih vrsta drva zaključeno je da je borovina imala najveću raznolikost vrsta kukaca, a slijedile su jelovina, hrastovina i bukovina. U studiji su također opisane neke važne vrste kukaca koji razaraju drvo, a pripadaju porodicama Anobiidae, Buprestidae and Cerambycidae. Kukci vrsta Buprestis dalmatina (Mannerheim, 1837) (Coleoptera: Buprestidae), Leptura aurulenta (Fabricius, 1792) (Coleoptera: Cerambycidae) i Stictoleptura scutellata (Fabricius, 1781) (Coleoptera: Cerambycidae) također razaraju drvo i prvi su put zabilježeni u Zapadnoj crnomorskoj regiji u Turskoj

Visionary Leadership Phenomenon in School Management

The aim of this study is to examine the concept of vision and visionary leadership, of which importance is being understood more and more in the management of educational institutions, and to reveal the positive differences between school administrators with visionary leadership characteristics. In the study, which was designed as a review article, the concepts of leader, manager, vision, and visionary leader were considered in the literature, and the features of visionary leadership, which are open to change and innovation, constantly improving themselves, inspiring the people they work with, guiding them, walking the path together and helping them when necessary, realizing the goals determined have been revealed. Therefore, it has been revealed that visionary school administrators are more peaceful and happier with the internal and external stakeholders they work with in their institutions, they move more confidently to the place where they are thought to be in the future determined for the institution, and that their institution is more preferable than the equivalent institutions around it. Besides, it has been indicated that the school includes innovative educational practices and student-centered studies, supports pluralistic participation in all areas, and shares its authority by giving responsibility. In this regard, the necessity of making legal arrangements that will reveal visionary leaders is an inevitable requirement for the future of the country and the accomplishment of the institutions

The effect of log seasonality on the reproductive potential of Monochamus galloprovincialis Olivier (Coleoptera : Cerambycidae) reared in black pine logs under laboratory conditions

WOS: 000251725200007Monochamus galloprovincialis (Olivier) is the vector of the pinewood nematode, Bursaphelenchus xylophilus (Steiner and Buhrer) Nickle, in Europe and Asia. Reproduction is probably the most important event in the life history of insects and may be affected by a number of factors, such as seasonal changes in larval or adult nutrition. In this study the effect of season on the reproductive potential of M. galloprovincialis females reared in black pine logs was investigated by constructing fertility tables for each of 43 pine logs that differed only in the season that they were cut. Population parameters were compared among 3 seasonal cohorts. The intrinsic rate of increase and related population parameters of the beetles that emerged from autumn logs were mostly higher than for beetles that emerged from spring and summer logs. These results suggest that seasonal differences in the nutritional quality of the logs (for immature development) and pine twigs (for adult feeding) may have caused the observed differences in M. galloprovincialis survival and reproduction
