Tüketicilerin Çirkin (Mükemmel Olmayan) Meyve ve Sebze Tüketimine Yönelik Tutum ve Davranışlarının Belirlenmesi: Bornova İlçesi Örneği

Çirkin gıda şekil, boyut ve renk farklılıkları gibi kusurlar nedeniyle standart dışı olan meyve ve sebzeleri kapsamaktadır. Tüketicilerin bu ürünlere yönelik tutum ve davranışları ürün kayıpları açısından tüm dünyada önemli hale gelmiştir. Bu çalışmanın amacı İzmir ili Bornova İlçesi’nde tüketicilerin çirkin meyve ve sebze tüketme eğilimleri ile bu ürünlerin tüketimine ilişkin tutum ve davranışlarını belirlemektir. Araştırma verileri 110 tüketici ile yüz yüze görüşülerek yapılan anketlerden elde edilmiştir. Satın alma eğilimini etkileyen tüketici tutum ve davranışlarının belirlenmesinde Beşli Likert Ölçeği kullanılmıştır. Araştırma sonuçlarına göre çirkin meyve sebze satın alma eğilimini etkileyen en önemli faktörün fiyat olduğu saptanmıştır. Bu ürünlerin fiyatlarının standart görünümlü ürünlerin fiyatlarından daha ucuz olmasının tüketim eğilimini arttırması beklenen en önemli unsur olduğu belirlenmiştir. Bu nedenle, çirkin (mükemmel olmayan) meyve ve sebzeler, perakende satış yerlerinde ayrı tezgahlarda ve daha düşük fiyatlarla satılabilir.

Determination of Biological Properties of Plutella xylostella (Linnaeus, 1758) (Lepidoptera: Plutellidae)

Plutella xylostella (Linnaeus, 1758), the diamondback moth is an important pest in Brassicae cultivars in the world. However, description regarding different biological stages and information about performance parameters of P. xylostella are important to survey in fields and design an effective management. In this study, wild population of diamondback moth was adapted on white cabbage then cauliflower, broccoli and white cabbage leaves were tested under laboratory conditions at 20±2°C, 50% relative humidity and 16:8 (L:D) photoperiod. The development times were 23.41±0.38 days on white cabbage, 25.12±0.56 days on cauliflower and 26.05±0.56 days on broccoli leaves. The generation times were 25.03±0.42 days on cauliflower, 29.99±1.49 days on broccoli and 30.47±1.04 days on white cabbage leaves. The eggs were laid individually or in the shape of small groups on the host leaves. There were 4 instars based on molting and head capsule diameters of all tested hosts. In this study, durations of larval stages, the number of laid eggs, larval sex differentiation and fitness parameters of the diamondback moth were determined on cauliflower, broccoli and white cabbage host plants.
