Investigation of Correlation of Syrup Sugar Content with Colony Traits and Syrup Consumption in Bumblebee

Öz

This study was carried out to research the effects of feeding with syrup containing different amount of sugar on egg laying and colony foundation success and other colony development traits in bumblebees. For this purpose, 80 Bombus terrestris queens, which hibernated and were got ready to egg laying were used. Queens were randomly divided into four groups that each of them containing 20 queens. Four syrup containing different amount of sugar (35, 45, 55 and 65 brix degree) were tested in each group. Queens and colonies in all groups were also fed ad-libitum with the same fresh thawed pollen. According to results, syrup sugar content affected the colony foundation performance of queens in B. terrestris. However, syrup sugar content had no significant effect on the number of individuals produced and other colony development characteristics. In addition, the increase of sugar content of syrup reduced the amount of syrup consumption.

Bombus Arılarında Şurup Şeker İçeriği ile Koloni Özellikleri ve Şurup Tüketimi Arasındaki İlişkinin İncelenmesi

Öz

Bu çalışma bombus arılarının kitlesel üretiminde farklı şeker içeriğine sahip şuruplar ile beslemenin ana arıların yumurtlama ve koloni oluşturma başarısı ve yetiştirilen kolonilerin gelişim özellikleri arasındaki ilişkiyi araştırmak amacıyla gerçekleştirilmiştir. Bu amaçla diyapoz dönemini tamamlamış ve yumurtlamaya hazır 80 adet Bombus terrestris ana arısı her grupta 20 adet olacak şekilde rastgele 4 gruba ayrılmıştır. Her bir grupta sırasıyla 35, 45, 55 ve 65 briks derecesi olmak üzere 4 farklı şeker içeriğine sahip şurup denenmiştir. Bütün gruplarda ana arılar ve koloniler şeker şurubu ile birlikte taze dondurulmuş polen ile ad-libitum olarak beslenmişlerdir. Sonuçlara göre B. terrestris arısında şurup şeker içeriğinin ana arının koloni oluşturma oranını etkilemektedir. Ancak şeker şurubu konsantrasyonunun üretilen birey sayıları ve diğer koloni gelişim özellikleri üzerine önemli bir etkisinin olmadığı belirlenmiştir. Ayrıca şurup şeker içeriğinin artması şurup tüketimini azaltmıştır.
