Abstract

Bu çalışmanın temel amacını, sahip olduğu yüksek
protein ve yağ içeri ile özellikle kanatlı ve pet hayvanı beslemede alternatif
bir besin katkısı olarak ön plana çıkan, T.
molitor’un, gelişme ve üreme karakterlerine ait genetik parametrelerin
tahmin edilmesi oluşturmaktadır. Çalışmada son dönem larva ağırlığı (SDLA),
pupa ağırlığı (PA), ergin ağırlığı (EA), pupa olma süresi (PS), pupada kalış
süresi (PKS) ve ergin olma süresi (ES) gelişim özellikleri, familya birey sayısı
(FBS) ise üreme özelliği olarak değerlendirilmiştir. Araştırmada son dönem
larva ağırlığı, pupa ağırlığı ve ergin ağırlığı özelliklerine ait kalıtım derecesi
tahminleri sırasıyla; 0,45, 0,65 ve 0,43 olarak tahmin edilmiştir. Çalışmada
gelişim sürelerine ilişkin kalıtım derecesi tahminleri ise; pupa olma süresi
için 0,27, pupada kalış süresi için 0,91 ve ergin olma süresi için 0,32 olarak
tahmin edilmiştir. Araştırmada familya birey sayısına ilişkin kalıtım derecesi
0,98 olarak tahmin edilmiştir. Bu sonuçlara göre T. molitor’ un gelişim özelliklerinin ıslah potansiyeli olduğu
söylenebilir.

Genetic Parameter Estimates for Growth and Development Characters in Tenebrio molitor (Mealworm)

Abstract

The main aim of this work is to estimate the genetic parameters of T. molitor, which is regarded as alternative nutrition for feeding poultry and pet animals due to its very high protein and fat content. In the study, larvae weight (LW), pupa weight (PW), adult weight (AW), duration of pupa (PT), duration of pupal stay (PST) and the duration of adulthood (AT) were considered as growth performance parameters; whereas the number of individuals in the family (FN) was treated as reproductive characteristic. Estimates of the heritability for larval weight, pupa weight and adult weight characteristics were: 0.45, 0.65, and 0.43, respectively. Estimates of heritability for duration of pupa, duration of pupal stay and the duration of adulthood were: 0.27, 0.91 and 0.32, respectively. The heritability for the number of individuals in the family was estimated to be 0.98. According to these results, it can be said that the developmental characteristics of T. molitor have genetic improvement potential.
