Abstract

A study was conducted to determine the optimum container size and rearing density to economize and optimize the mass rearing of Oenopia conglobata (Linnaeus, 1758) (Coleoptera: Coccinellidae) during 2017 in Şanlıurfa, Turkey. The experiment consisted of three types of containers of varying size (106, 310 and 785 ml, regarded as small, medium and large, respectively) and four different rearing densities of O. conglobata (1, 5, 10 and 20 larvae/container, regarded as low, moderate, medium and high rearing density, respectively). Oenopia conglobata was fed with the eggs of Ephestia kuehniella Zeller, 1879 (Lepidoptera: Pyralidae) throughout the study. The highest (100%) larval survival rate was recorded for all containers with low rearing density, whereas the lowest (31.5-35.0%) larval survival was observed in medium containers with medium and high rearing density. Medium containers at low rearing density had the shortest larval development period (8.6 d), while the shortest pupal development period (4.3-4.4 d) was in medium and large containers at medium and moderate density, respectively. The highest rearing cost wascomputed for small and medium containers at low rearing density, whereas the lowest rearing cost was incurred with largecontainers at high rearing density. Considering the survival rates, development periods and economic cost incurred; large containers with high rearing density is recommended for the economic and rapid mass rearing of O. conglobata.

Özet

Bu çalışma, 2017 yılında Şanlıurfa ilinde (Türkiye) Oenopia conglobata (Linnaeus, 1758) (Coleoptera: Coccinellidae)'nın laboratuvar koşullarında ekonomik ve hızlı kitle üretimi için optimum kap büyüklüğü ve yetiştirme yoğunluğunu belirlemek amacıyla yapılmıştır. Farklı şekil ve büyüklükte üç farklı kap (106, 120 ve 785 ml; sırasıyla küçük, orta ve büyük olarak isimlendirilen) ve dört farklı O. conglobata yetiştirme yoğunluğu (1, 5, 10 ve 20 larva/kap; sırasıyla düşük, orta, orta-yüksek ve yüksek yoğunluk olarak isimlendirilen) çalışmaya dahil edilmiştir. Oenopia conglobata çalışma boyunca Ephestia kuehniella Zeller, 1879 (Lepidoptera: Pyralidae) yumurtaları ile beslenmiştir. En yüksek (%100) larva canlılık oranı düşük yetiştirme yoğunluğunun denenen tüm kapların interaksiyonunda belirlenirken, en düşük (%31,5-35,0) larva canlılık oranı ise, orta ve yüksek yetiştirme yoğunluğunun orta büyüklükteki kap ile interaksiyonunda kaydedilmiştir. Düşük yoğunluk ve orta boy kap en kısa larva gelişim periyoduna (8,6 gün) sahipken, en kısa pupa gelişim periyodu (4,3-4,4 gün) sırasıyla orta ve orta-yüksek yoğunluğun orta ve büyük kap interaksiyonunda kaydedilmiştir. En yüksek yetiştirme maliyeti, düşük yoğunluğun küçük ve orta boy kap interaksiyonu için belirlenirken, en düşük yetiştirme maliyeti, yüksek yoğunluğa sahip büyük kaplarda olmuştur. Hayatta kalma oranları, gelişme dönemleri ve meydana gelen ekonomik maliyet dikkate alındığında; O. conglobata'nın ekonomik ve hızlı kitle üretimi için büyük kaplarda yüksek yetiştirme yoğunluklu üretim önerilmektedir.
