| dc.description.abstract | In 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. | |
| dc.description.abstract | Arastirmamizda un kurdu $Tenebrio$ $molitor$ L. kullanilmistir. Iki farkli besinin, farkli larval yogunlugunda $T.$ $molitor$’ un pupalasma orani ve pupadan çikis süresine etkisi arastirilmistir. Denemeler, sicakligi 27±2?C ve nisbi nemi %60±5 olan devamli karanlik laboratuvar kosullarinda yapilmistir. Arastirmada iki farkli besin tipi kullanilmistir. 1. besin; bugday rüseymi ve kuru mayadan olusurken, 2. besin; tam bugday unu ve misir unun (esit miktarda) dan olusmustur. Öncelikle denenen besin ortamlarinda böcekler yetistirilmistir. Her iki besin için de dört farkli larva yogunlugunda deney seti hazirlanmistir. Plastik kaplarda larva sayisi, 20, 60, 200 ve 600 olacak sekilde ayarlanmistir. Biyolojik testlerde 50 mg-120 mg arasi küçük larvalar tercih edilmistir. Pupalasma yüzdesi her iki besinde de 200 larva yogunlugunda azalmis, 600 larva yogunlugunda ise keskin bir düsüs olmustur. Özellikle yogunlugun ortaya çikardigi negatif etkilerin 2. besinde daha bariz ortaya çiktigi tespit edilmistir. Pup süreleri bakimindan degil, özelikle larvalarin pupalasmasinda yogunluktaki etkiler daha bariz olmustur. Sonuç olarak, canli yem olarak çok fazla sayida talep gören $T.$ $molitör$ den daha fazla verim almak, üreme hizini arttirmak bakimindan larva yogunlugunun özellikle 200 ün üzerinde olmamasi avanvajli olacaktir. | |
