The survey was conducted during the period 2019-2022 in the vineyard areas of Diyarbakır, Mardin, Elazığ, Batman, and Şanlıurfa provinces. Studies were carried out to identify parasitoids of the wood-tissue pest Chlorophorus damascenus, which has recently become a problem in vineyard areas that are old and exposed to stress factors. Dolichomitus populneus (Ratzeburg, 1848) (Hymenoptera: Ichneumonidae), and Iphiaulax impostor (Scopoli, 1763) (Hymenoptera: Braconidae) were obtained from Chlorophorus damascenus. C. damascenus was a new host for D. populneus
The Examination of the Relatıonship Between Nomophobia, Coping With Stress and Perceived Social Support Levels of Adolescent Students
Yüksek Lisans TeziBu araştırmanın amacı ergenlerin nomofobi, algılanan sosyal destek ve stresle başa çıkma düzeyleri
arasındaki ilişkiyi incelemektir. Bu amaçla araştırmanın çalışma grubunu 2020-2021 eğitim öğretim
yılında Şanlıurfa ili merkez ilçelerinin çeşitli ortaokul ve liselerinde ve farklı sınıf düzeylerinde
öğrenimine devam eden 553‟ü (%69,7) kız, 240‟ı (%30,3) erkek olmak üzere toplam 793 öğrenci
oluşturmuştur. Katılımcıların kişisel bilgilerini belirlemek amacıyla "Kişisel Bilgi Formu‟, nomofobi
düzeylerini belirlemek amacıyla "Nomofobi Yaygınlığı Ölçeği", algılanan sosyal destek düzeylerini
belirlemek amacıyla "Çok Boyutlu Algılanan Sosyal Destek Ölçeği‟ ve stresle başa çıkma düzeylerini
belirlemek amacıyla da "Ergenler İçin Başa Çıkma Ölçeği" kullanılmıştır. Verilerin analizinde
değişkenler arasındaki ilişkiyi ortaya koymak amacıyla Pearson Momentler Çarpım Korelâsyon Katsayısı
ve ilgili değişkenlerin sosyo-demografik bilgiler açısından incelenmesi amacıyla T Testi ve Anova Testi
kullanılmıştır.
Araştırmanın sonuçlarına göre nomofobi ile aktif başa çıkma arasında negatif yönde düşük düzeyde,
nomofobi ile kaçınan başa çıkma arasında pozitif yönde düşük düzeyde, nomofobi ile olumsuz başa
çıkma arasında pozitif yönde düşük düzeyde anlamlı ilişkiler elde edilmiştir. Ayrıca algılanan sosyal
destek ile aktif başa çıkma arasında pozitif yönde orta düzeyde, algılanan sosyal destek ile kaçınan başa
çıkma arasında negatif yönde düşük düzeyde, algılanan sosyal destek ile olumsuz başa çıkma arasında
negatif yönde düşük düzeyde anlamlı ilişkiler ortaya çıkmıştır.
Nomofobi düzeylerinin cinsiyet, sınıf düzeyi, okul türü, günlük ortalama telefon kullanım süresi
değişkenlerine göre anlamlı şekilde farklılaştığı ancak kardeş sayısı, anne eğitim durumu ve baba eğitim
durumu değişkenlerine göre anlamlı şekilde farklılaşmadığı görülmüştür. Ayrıca algılanan sosyal destek
düzeylerinin yalnızca kardeş sayısı değişkenine göre anlamlı şekilde farklılaştığı ancak cinsiyet, sınıf
düzeyi, okul türü, anne-baba eğitim durumu ve günlük ortalama telefon kullanım süresi değişkenlerine
göre anlamlı şekilde farklılaşmadığı görülmüştür. Son olarak stresle başa çıkmanın alt boyutlarının ise
yalnızca cinsiyet, kardeş sayısı ve günlük ortalama telefon kullanım süresi değişkenlerine göre anlamlı
şekilde farklılaştığı ancak diğer değişkenlere göre anlamlı şekilde farklılaşmadığı görülmüştür.
Araştırmadan elde edilen bulgular ve sonuçlar ilgili literatür ışığında tartışılmıştır.The purpose of this research is to investigate relationship between nomophobia, perceived social support
and the levels of coping with stress of adolescents. For this purpose, 793 high school students (553
(69.7%) female and 240 (30.3%) male students) who continue their education from several high schools
in central district of ġanlıurfa in 2020-2021 academic year constitute the study group of this research. In
this research, Personal Information Form created by researcher, Nomophobia Prevalence Scale for the
datas concerning behavior of nomophobia, Multidimensional Perceived Social Support Scale for the datas
concerning level of perceived social support and Coping For Adolescents Scale for the datas concerning
coping with stress were used for data collection tools. Pearson Moment Correlation Coefficient, T Test,
Anova Test and other variables were used to reveal the relationship between variables in the analysis of
the data.
According to the result of research, it is observed that there are significant relations between the
nomophobia, perceived social support and coping with stress. It is found that there are significant
relations negatively low level between nomophobia and active coping with stress and positively low level
between nomophobia and avoidant coping with stress. Besides, it is found that there are significant
relations positively middle level between perceived social support and active coping with stress and
negatively low level between perceived social support and avoidant coping with stress and negatively low
level between perceived social support and negative coping with stress.
It was found that nomophobia of adolescents differed significantly according to gender, grade level,
school type and daily time of smart phone usage variables but it didn‟t differ significantly according to
the number of siblings and parental education status variables. Besides, it was found that perceived social
support of adolescents differed significantly according to only the number of siblings variable but it
didn‟t differ according to gender, grade level, school type, daily time of smart phone usage and parental
education status variables. Lastly, it was found that lower dimensions of coping with stress differed
significantly according to only gender, the number of siblings and daily time of smart phone usage
variables but it didn‟t differ significantly according to other variables.
Findings from research and results were discussed in the light of the literature
Investigations on biological characteristics of Pseudococcus comstocki (Kuwana) (Hemiptera: Pseudococcidae) on different two mulberry species and different temperatures
Asya kökenli unlubit Pseudococcus comstocki (Kuwana) (Hemiptera: Pseudococcidae) polifag kozmopolit bir türdür. Son yıllarda Avrupa ülkelerinde hızla yayılan bu tür daha geniş bir dağılıma sahip olmaktadır. Bu çalışmada P. comstocki’nin farklı sıcaklık koşullarında (18, 23, 28 ve 20-32°C) ve iki farklı dut türü (Morus alba ve M. nigra) (Moraceae) üzerinde gelişme dönemlerinin süresi, ölüm oranları, üreme kapasitesi, dişi-erkek oranları, termal konstantı ve gelişme eşiğinin belirlenmesi amaçlanmıştır. Çalışma sonucunda M. nigra üzerinde beslenen popülasyonun (rm= 0.123 dişi/dişi/gün; R0= 108.933 dişi/dişi; T0= 38.160 gün; DT= 5.639 gün) M.alba üzerinde beslenen popülasyondan (rm= 0.115 dişi/dişi/gün; R0= 84.281 dişi/dişi; T0= 38.600 gün; DT= 6.032 gün) daha iyi geliştiği tespit edilmiştir. P. comstocki’nin sıcaklığa bağlı olarak gelişimi incelendiğinde türün en hızlı 28°C’de ergin olduğu belirlenmiştir. Zararlının M. nigra’da gelişme eşiğinin (t) 7.87°C, termal konstantının (ThC) K= 513 gün-derece; M. alba’da gelişme eşiğinin (t) 7.76°C, termal konstantının (ThC) K= 518 gün-derece olduğu saptanmıştır.Asiatic originated Pseudococcus comstocki (Kuwana), the Comstock mealybug (Hemiptera: Pseudococcidae) is polyphagous cosmopolite species. Nowadays it is spreading through to Europe and becoming wide distribution. In this study, the developmental time, survival and fecundity of P. comstocki on two mulberry species (Morus alba and M. nigra) (Moraceae) were studied at four different temperatures (18±1, 23±1, 28±1 and 20-32°C) and thermal constant was calculated. According to results, it appears that performance of P. comstocki and, consequently, its population increase were affected by feeding with different mulberry species and at different temperatures, and M. nigra seems to be more likely susceptible to the mealybug than M. alba in each temperatures because it displayed the highest performance on this host plant. The results showed that the population on M. nigra (rm = 0.123 female/female/day; R0 = 108.933 female/female; T0= 38.160 day; DT= 5.639 day) developed better than that on M. alba (rm= 0.115 female/female/day; R0 = 84.281 female/female; T0= 38.600 day; DT= 6.032 day) at 28°C. It was found that there was an inverse relationship between the growth period of the population and the temperature, development of the mealybug becoming fully grown was the fastest on both Morus species at 28 °C. The threshold for development (t) and the thermal constant (ThC) of the mealybug on M. nigra was determined as 7.87 °C, K = 513 degree-days respectively; while on M. alba, these parameters were found to be 7.76 °C and K = 518 degree-days respectively

Effects of diabetes mellitus on left atrial volume and functions in normotensive patients without symptomatic cardiovascular disease
Purpose: Left atrial (LA) size has been shown to be a predictor of adverse cardiovascular outcomes. The aim of the study was to evaluate the direct effect of diabetes mellitus (DM) on left atrial volume and phasic functions by using real-time three-dimensional echocardiography (RT3DE) in a population of patients free of symptomatic cardiovascular disease and hypertension. Methods: Comprehensive transthoracic echocardiographic examination was performed on 40 consecutive patients with DM (20 male, age: 50.5 +/- 7.3 years) and 40 healthy controls (20 male, age: 48.4 +/- 6.7 years). In addition to conventional 2D echocardiographic measurements RT3DE was performed to assess LA volumes and phasic functions. Results: There were no significant difference between groups regarding parameters reflecting LV systolic function as LV diameters and ejection fraction. However, regarding parameters reflecting LV diastolic function; transmitral deceleration time and E/E' ratio values were significantly higher and majority of early diastolic tissue Doppler velocity values were significantly lower in diabetic patients compared with controls. RT3DE demonstrated significantly higher LA maximum and minimum volumes for diabetic patients compared with controls (40.9 +/- 11.9 vs 34.6 +/- 9.3 mL, p: 0.009 and 15.6 +/- 5.9 vs 11.9 +/- 4.6 mL, p: 0.002, consecutively). LA total emptying fraction (TEF), expansion index (El) and active emptying fraction (AEF) were found to be significantly lower in diabetics reflecting depressed LA reservoir and pump functions. There was no significant difference between groups regarding passive emptying fraction (PEF) which is assumed to be a marker of left atrial conduit function. Conclusion: Patients with type 2 diabetes mellitus were found to have increased LA volume and impaired atrial compliance and contractility. Evaluation of asymptomatic diabetic patients by using RT3DE atrial volume analysis may facilitate recognition of subtle myocardial alterations related with type 2 diabetes. (C) 2014 Elsevier Inc.
