Abstract

Second screen use is becoming increasingly popular among young people. Türkiye can be expressed as a place where the use of devices such as TV, phone, tablet and computer is widespread. This study, which is based on the uses and gratifications approach, seeks answers to the following questions: a) which devices are used as second screens, b) with which TV programs they are used, c) with what kind of motivations they are used by Generation Z members who still watch TV. We collected data from university students using a questionnaire and the convenience sampling method, which is a type of non-probabilistic sampling, through SPSS. The data showed that Generation Z primarily uses smartphones as second screens, and only a few use second screen applications on their mobile phones. Music programs are the most popular thematic programs watched together with the second screen. Women tend to use their second screens for watching series and shopping. Generation Z prefers using a ‘smartphone with computer’ as a second screen. Future studies could investigate the motivations of students and academics to use second screens in distance education. Additionally, future studies can investigate the usage habits of second screens in second language learning. [ABSTRACT FROM AUTHOR]

Abstract

Recent research shows that Dicranumspecies can be used to ameliorate the negative effects of honeybee bacterial diseases and that novel compounds isolated from these species may have the potential to treat bacterial diseases. This study aimed to investigate the efficacy of Dicranum polysetumSw. against American Foulbrood using toxicity and larval model. The effectiveness of D. polysetumSw. ethanol extract in combating AFB was investigated in vitro and in vivo. This study is important in finding an alternative treatment or prophylactic method to prevent American Foulbrood disease in honey bee colonies. Spore and vegetative forms of Paenibacillus larvaePB31B with ethanol extract of D. polysetumwere tested on 2040 honey bee larvae under controlled conditions. Total phenolic and flavonoid contents of D. polysetumethanol extracts were determined as 80.72 mg/GAE(Gallic acid equivalent) and 303.20 µg/mL, respectively. DPPH(2,2-diphenyl-1-picrylhydrazyl) radical scavenging percent inhibition value was calculated as 4.32%. In Spodoptera frugiperda(Sf9) and Lymantria dispar(LD652) cell lines, the cytotoxic activities of D. polysetumextract were below 20% at 50 µg/mL. The extract was shown to considerably decrease infection in the larvae, and the infection was clinically halted when the extract was administered during the first 24 h after spore contamination. The fact that the extract contains potent antimicrobial/antioxidant activity does not reduce larval viability and live weight, and does not interact with royal jelly is a promising development, particularly regarding its use to treat early-stage AFB infection.

Abstract

Malacosoma neustria (Linnaeus, 1758) (Lepidoptera: Lasiocampidae), Avrupa, Asya ve Kuzey Afrika'ya dağılmış dünya çapında bir zararlıdır. Elma, armut, erik, söğüt ve meşede ekonomik kayıplara neden olur. Bu çalışmada, Türkiye'nin Orta Karadeniz Bölgesi’nde bulunan Samsun'dan 2015-2016 yıllarında toplanan M. neustria larvalarından bakulovirüs izole edilmiştir. Ölü larvalardan elde edilen oklüzyon badilerin (OB) elektron mikroskobu analizi, çoklu nükleokapsidlere sahip yeni bir izolat (ManeNPV-T4) olduğunu gösterdi. Kimura iki-parametre analizi ve filogenetik ağaç, ManeNPV-T4 izolatından elde edilen kısmi lef-8, lef-9 ve polh genlerinin birleştirilmiş nükleotit ve amino asit dizilerine dayanarak, diğer 51 baculovirüsünki ile karşılaştırıldı. Üçüncü evre M. neustria larvalarına uygulanan insektisidal aktivite testleri sonucunda %48 ile %100 arasında ölüm gözlendi. ManeNPV-T4'ün M. neustria için LC50 değeri 0,78 x 103 OB/ml olarak belirlendi. Ek olarak, viral izolat Spodoptera exigua (Hübner, 1808) (Lepidoptera: Noctuidae), Lymantria dispar (Linnaeus, 1758) (Lepidoptera: Erebidae), Hyphantria cunea (Drury, 1773) (Lepidoptera: Arctiidae) ve Helicoverpa armigera (Hübner, 1805) (Lepidoptera: Noctuidae) larvaları üzerinde %50’den düşük ölüm oranı oluşturdu. Sonuç olarak, bu yeni nükleopolihedrovirüs M. neustria ve diğer lepidopter larvalarına karşı da enfektiviteye sahiptir., Malacosoma neustria (Linnaeus, 1758) (Lepidoptera: Lasiocampidae) causes economic losses in apple, pear, plum, willow, oak and other economically important trees. In this study, an alphabaculovirus was isolated from the larval population of M. neustria from Samsun in the central Black Sea Region of Turkey between 2015 and 2016. Electron microscope analysis of occlusion bodies (OBs) obtained from dead larvae showed that the nucleocapsids of a new isolate (ManeNPV-T4) are multiply enveloped. The Kimura two-parameter analysis and the phylogenetic tree were performed based on concatenated nucleotide and amino acid sequences of the partial lef-8, lef-9 and polh genes from ManeNPV-T4 isolate compared to those of other 51 baculoviruses. Insecticidal activity tests against third instar M. neustria larvae produced 48 to 100% mortalities. The LC50 of ManeNPV-T4 was 0.78 x 103 OBs/ml in M. neustria. Additionally, the isolate caused mortalities lower than 50% in Spodoptera exigua (Hübner, 1808) (Lepidoptera: Noctuidae), Lymantria dispar (Linnaeus, 1758) (Lepidoptera: Erebidae), Hyphantria cunea (Drury, 1773) (Lepidoptera: Arctiidae) and Helicoverpa armigera (Hübner, 1805) (Lepidoptera: Noctuidae) larvae. Consequently, the new nucleopolyhedrovirus is infectious on M. neustria larvae and other lepidopterans.
