Dünyada sayıca en çok üretimi yapılan bombus türü olan Bombus terrestris arıları hem doğal de kültüre alınmış çiçekli bitkilerin tozlaşmasına önemli katkılar sunmaktadır. Kontrollü koşullarda B. yetiştiriciliğinde çiftleşme ve diyapoz aşamaları diğer tüm aşamalar gibi kritik öneme sahiptir. Bu aşamaların başarılı olmasında kolonilerin ana arıların beslemesinin payı oldukça fazladır. yetiştirici...

Methylation has previously been associated with allele specific expression in ants. Recently, we found methylation is important in worker reproduction in the bumblebee Bombus terrestris. Here we searched for allele specific expression in twelve genes associated with worker reproduction in bees. We found allele specific expression in Ecdysone 20 monooxygenase and IMP-L2-like. Although we were un...

The cephalic labial gland secretion of Bombus semenoviellus males was analyzed, and its chemical composition is reported for the first time. The secretion functions as sex or marking pheromone. Eighty compounds were identified in the secretion, the main one being all-trans-geranylgeranyl acetate (48%). The same compound was shown to form 87% of the labial gland secretion of B. cullumanus males....

Secretions of three different glands (mandibular gland, labial gland, and Dufour's gland) of virgin queens of five bumblebee species (Bombus lucorum, B. lapidarius, B. hypnorum, B. pascuorum, and B. terrestris) were analysed. Around 200 compounds were identified in the secretions. The compositions of the secretions of labial and mandibular glands were species-specific. Dufour's gland of all spe...
