Bu çalışma ile kitlesel
olarak en yaygın şekilde yetiştirilen bombus arısı türü olan Bombus terrestris işçi arılarının bazı
morfolojik özelliklerinin belirlenmesi ve bu morfolojik özelliklerin hem kendi
aralarında hem de işçi arıların yuvaya taşıdığı polen yükü ile ilişkilerin
araştırılması amacıyla gerçekleştirilmiştir. Çalışmanın ilk aşamasında 100 adet
işçi arının polen
toplama ve taşıma performansını etkileyebileceği düşünülen ağırlık, dil
uzunluğu, ön kanat genişliği, ön kanat
uzunluğu, ön kanat indeksi, femur uzunluğu, tibia uzunluğu, metatarsus
genişliği, metatarsus uzunluğu, arka
bacak uzunluğu ve metatarsus indeksine ilişkin morfolojik özellikleri
belirlenmiştir. İşçi arıların ağırlığı ve dil uzunluğu sırasıyla 0,222 ± 0,005 gram ve 8,080 ± 0,114 milimetre olarak belirlenmiştir. İkinci aşamada ise
araziye yerleştirilen kolonilerin önünden yakalanan polen yüklü 50 adet işçi
arı için belirtilen morfolojik özellikler belirlenmiştir. Elde edilen sonuçlara
göre B. terrestris işçi arılarının
morfolojik özellikleri bakımından önemli varyasyon belirlenmiştir. Ancak polen
yükü ile sadece dil uzunluğu arasında önemli korelasyon hesaplanmış, diğer
belirlenen morfolojik özelliklerinin işçi arıların taşıdıkları polen yükü
üzerine güçlü bir etkisi belirlenmemiştir.

Determination of Some Morphological Characters of Bombus terrestris L. Workers and Effect of Morphological Traits on Pollen Load

Öz

This study was conducted to determine some
morphological traits of Bombus terrestris
workers which is the most widely reared species. The correlation both between
morphological traits and between pollen load and morphological traits of
workers was also investigated. In the first stage of the study, some
morphological traits which may affect the collection and transporting of pollen
such as weight, tongue length, forewing width, forewing length, forewing index,
femur length, tibia length, metatarsus width, metatarsus length, hind leg
length and metatarsal index for 100 workers were determined. The worker weight
and tongue length were determined as 0.222 ± 0.005 gram and 8.080 ± 0.114 millimeters, respectively. In the second stage,
stated morphological traits were determined for 50 workers with pollen load
caught in front of the colonies in the field. According to results, significant
variation was determined in terms of the morphological traits of B. terrestris workers. However, a significant
correlation was calculated for only pollen load and tongue length. No
significant strong effect of other morphological traits on pollen load
transported by workers was determined.
