This study aimed to report this invasive species and its parasitoids on Eucalyptus growing area in Northern Cyprus. G. brimblecombei infested leaves were collected and brought to the laboratory for identification and collection of parasitoids emerged from the pest. In this paper, presence of G. brimblecombei and the parasitoid of the red gum lerp psyllid Psyllaephagus bliteus Riek （Hymenoptera： Encyrtidae） were reported for the first time in Northern Cyprus. Detailed information about the pest and its parasitoids were discussed.展开更多

Data were collected by the way of a self-administered questionnaire with the study sample comprising students from bachelor degree programs. The results of the study offer an important view regarding the motivation for attending cultural tourism among Turkish students. The paper ends with both practical implications for the cultural tourism organizers and some theoretical contribution to the research of cultural tourism.展开更多

For this purpose, samples from five different rock groups including igneous(andesite, granite, andesitic tuff) and sedimentary(limestone, sandstone) exposed in Gümü?hane city which is from mountainous area of north-eastern Turkey, have been compiled. Measurements were taken on the samples left for saturation under laboratory conditions as a result of which the degree of saturation values at the end of these time periods were determined. Similarly, at the end of 48 hours, the samples were left to dry under atmospheric conditions in the laboratory environment and their time dependent degree of saturation were also calculated at different times. The changes as a function of time in the degree of saturation were then examined mathematically using non-linear, exponential and logarithmic functions. Graphs and equations related with the acquired time-degree of saturation values and the correlation coefficient(r) values for these equalities have indicated a high accordance between time and degree of saturation for the studied rock groups. The applied methodology will be beneficial for determining the degree of saturation based on time for engineering studies that will be carried out in similar lithologies.展开更多
