Bombus Arılarında Tarlacı İşçi Arıların Entomopatojen Funguslara Maruz Kalması Kolonideki Diğer Bireyleri Nasıl Etkiler?

lecani strain V1-1 and % 1.5 Paecilomyces fumosoreus strain PFs-1) on Bombus terrestris workers was investigated under controlled laboratory conditions. Workers were exposed to recommended doses of entomopathogenic fungi by topical application and dry film method. Of the 30 workers in each colony, 15 of them were marked in blue and 15 of them were marked in red on their thorax. While the blue marked workers were put back to their own nests without any application, red marked workers were put back after entomopathogenic fungi exposure. Thus, it was investigated whether the entomopatogenic fungi exposure of some workers in B. terrestris colonies causes death or not in (i) in exposed workers (ii) in other workers in the same colony, and (iii) in workers that emerged after entomopathogenic fungi application in the same colony. Results showed that death values for all three cases were low level to adversely affect the colony development.
