Öğe Effects of Continuous Ligth and Darkness on the Total Lipid Amounts of Achroia grisella (Lepidoptera: Pyralidae)’s Different Ages Adults(Kirgizistan Türkiye Manas Üniversitesi, 2013) Koç, Yesim; Sönmez, EvrimAchroia grisella is a harmful species for combs and it’s larvae are known as causing serious damages in beekeeping. It is important to know the biological characteristics of this insect for biological control and laboratory studies. Photoperiod affects many metabolic and physiological activities of organisms. In this study, were investigated the effect on the amount of total lipid in continuous light and continuous darkness in A. grisella that different age. Studies were carried out under the laboratory conditions at 28 ± 2 ° C temperature and 65 % ± 5 relative humidity. Illumination was done with 40 W fluorescent bulbs in different photoperiod regimes. Calculating the amount of lipids for analysis, van Handel (1985) test was used. Both females and males, the amounts of lipids decreased as the adult aging. Results from this study is show that increase of dark period, caused decrease amounts of lipids. The amount of lipid in females is more than those observed for malesÖğe Farkli Besin Tiplerinin Ephestia kuehniella Zeller (Lepidoptera: Pyralidae)’nin Total Lipit ve Total Yag Asidi Yüzdelerine Etkileri(Bitlis Eren Üniversitesi, 2019) Sönmez, Evrim; Koç, Yesim; Özcan, ÖzgürDenemelerde degirmen güvesi Ephestia kuehniella kullanildi. Denemeler 28°C, 65±5 sicaklik venem sartlarinda ve devamli karanlik kosullarda yapildi. Besin olarak bugdayunu, misir unu, rüseym katkili un ve rüseym kullanildi. Belirtilen besinlerdeyetistirilen larva, pup ve ergin disi ile erkeklerden 3’er tekrar olmak üzere40 birey alindi. Toplamda her bir deneme için 120 birey kullanildi. Toplamlipit ve toplam yag asitlerinin özütlenmesinde Folch ve ark., (1956)’ningelistirdikleri yöntem uygulandi. Denemeler sonucunda en agir larva misirununda, pup rüseym katkili unda, disi bugday ununda, erkek ise rüseymdeyetistirilenlerde bulundu. Total lipit larvada en fazla bugday ununda, pup,disi ve erkekte misir ununda yetistirilenlerde tespit edildi. Total yag asidiise larva ve pupta en fazla misir ununda, disi ve erkekte ise rüseym katkiliunda yetistirilenlerde bulundu. Degerler arasindaki farklar genellikleistatistiksel olarak farkli tespit edildi.Öğe Fen Bilgisi Ögretmen Adaylarinin Hücre Organelleri Konusundaki Kavramsal Anlama Düzeyleri(Karabük Üniversitesi, 2018) Koç, Yesim; Sönmez, EvrimBu çalismanin amaci; Genel Biyoloji I Dersini almis Fen Bilgisi Ögretmen Adaylarinin, hücre organelleri konusundaki kavram yanilgilarini ortaya çikarmak ve bilgi düzeylerini ölçmektir. Bu sekilde hücre ve organelleri konusundaki hangi kavramlarin daha çok akilda kaldigi, hangi bilgilerin unutuldugu tespit edilerek bir takim sonuçlar ve öneriler ortaya çikarilacaktir. Ögrencilerde var olan kavram yanilgilarinin hangi konularda yogunlastiginin belirlenmesi ve hangi konulari ve kavramlari ögrenmekte daha çok güçlük çektiklerinin ortaya konmasi, buna bagli olarak bir ögrenim ortami ve metodu gelistirmek fen bilimleri egitiminde çok önemlidir. Çalisma, Sinop Üniversitesi Egitim Fakültesi Fen Bilgisi Ögretmenligi 3. Sinif’ta ögrenim gören 45 ögretmen adayla gerçeklestirilmistir. Bu arastirmada nitel arastirma yöntemi kullanilmistir. Ögrencilere hücre organelleri konusunda 13 açik uçlu sorudan olusan form uygulanmistir. Elde edilen veriler içerik analiz yöntemiyle analiz edilmistir. Arastirmaya dahil edilen ögrencilerin lisans ögrenimlerinin 2. sinifindaki Genel Biyoloji I dersini almis olmalarina ragmen, özellikle organeller konusundaki bazi önemli kavramlari hatirlayamadiklari veya hatali ve eksik bilgiye sahip olduklari görülmüstür. Elde edilen bulgular göz önüne alinarak var olan eksik veya yanlis bilgilerin düzeltilmesi ve kalici bilgiye ulasmasi için çesitli öneriler verilmistir.Öğe The Effect of Larval Density on Pupation Rate and Time to Emergence from Pupation in $Tenebrio$ $molitor$ Linnaeus, 1758 (Coleoptera: Tenebrionidae) Reared on Two Different Feeds(Sinop University, 2024) Koç, YesimIn our research, the yellow mealworm, $Tenebrio$ $molitor$ L. was used. The effects of two different foods on the pupation rate and time to emergence from pupation of $T.$ $molitor$ at different larval densities were investigated. The experiments were carried out under continuous dark laboratory conditions with a temperature of 27±2?C and a relative humidity of 60%±5%. Two different nutrient and four larval density groups were used in the study. The first nutrient composition consisted of dry yeast and wheat germ (150 gr in total, 1/2) The second nutrient composition consisted of whole wheat flour and corn flour (150 gr in total, 1/1). Insects were bred primarily on the tested nutrient media. Experimental sets were prepared at four different larval densities for both foods. The number of larvae in plastic containers was adjusted to 20, 60, 200 and 600. To ensure equality, all larvae were selected from small larvae. (between 50 mg-120 mg). In our study, pupation rates were high, especially in groups consisting of 20 and 60 larvae. The percentage of pupation decreased at 200 larval densities and sharply decreased at 600 larval densities in both diets. Especially the negative effects of the density are more obvious in the second food. The effects on intensity were more pronounced, especially in pupation of larvae, not in terms of pup time. As a result, it would be advantageous for the larvae density not to be above 200 in terms of getting more yield and increasing the reproduction rate from $T.$ $molitor$, which is demanded in large numbers as live feed. In conclusion, for the production of $T.$ $molitor$, which is commonly used as live feed, it is preferable to have a larval density below 200 in order to get a higher yield and better reproduction rates.
