Bombus Arısı (Bombus terrestris) Kolonilerinde Üretilen Farklı Kast Gruplarının Kanat Damar Özellikleri

Abstract

Bombus arılarında bazı türler belirgin morfolojik özellikleri sayesinde birbirinden ayrılabilirken, bazı türlerin tanımlanmasında morfolojik özellikler yeterli değildir. Kanat damar özelliklerinin kullanılması arı tür veya alt türlerinin tanımlamasında kullanılan önemli yöntemlerden birisidir. Bombus terrestris kolonilerinde yaşam döngüsü boyunca (i) işçi arılar, (ii) genç ana arılar, (iii) kurucu ana arı tarafından yumurtlanan haploid yumurtalardan üretilen erkek arılar ve (iv) işçi arılar tarafından yumurtlanan haploid yumurtalardan üretilen erkek arılar olmak üzere 4 farklı kast grubuna ait bireyler yetiştirilmektedir. Bu çalışmada B. terrestris kolonilerinde üretilen bu 4 farklı kast grubuna ait bireylerin kanat damar özellikleri incelenerek bu özelliklere ait değerler belirlenmiştir. Bu kapsamda araştırmada 160 adet (her bir kast grubu için 40 adet) birey kullanılmıştır. Çalışma kapsamında belirlenen her bir özellik için gruplar arasında görülen fark istatistiki olarak önemli bulunmuştur (P<0.05). Çalışma sonuçları bombus arılarının kanat özellikleri ile ilgili gelecekte yapılacak çalışmalara kaynak oluşturacak niteliktedir.

WING VEIN CHARACTERISTICS OF DIFFERENT CASTE GROUPS PRODUCED IN BUMBLEBEE (Bombus terrestris) COLONIES

Abstract

Some species of bumblebees can be discriminated from each other based on distinct morphological features, while for some species, morphological characteristics are not sufficient for identification. The use of wing vein characteristics is one of the important methods used in the identification of bee species or subspecies. In Bombus terrestris colonies, individuals belonging to four different caste groups are grown throughout the life cycle, namely (i) worker bees, (ii) young queen bees, (iii) male bees produced from haploid eggs laid by the founding queen, and (iv) male bees produced from haploid eggs laid by worker bees. In this study, wing vein characteristics of individuals belonging to these 4 different caste groups produced in B. terrestris colonies were examined, and values for these characteristics were determined. For this purpose, 160 individuals (40 for each caste group) were used in the study. The difference between the groups for each characteristic determined in the study was found statistically significant (P<0.05). The results of the study are of a nature to contribute to future research on wing characteristics of bumblebees.
