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.

This research was performed to determine the breeding activities of small ruminant husbandry enterprises and their general problems in central district of Van. Research material has been created 168 small ruminant firms in the villages of the central district of Van. Coming together in the form of small family-run business that operates form the common herd (84.5 %). In respect to using the shepherd, a member of family is selected as shepherd in family run while temporary or permanent shepherds are procured according to number of herd in common lot. According to survey result, average milk production per the farming of small ruminant is determined as 38.89 kg. Cultivators have expectations such as free veterinary service, long-term credit, supply of breeding animals and products in the price stability from government. The most important issues of sheep and goat farming are the difficulty of finding shepherd, lack of veterinary services, lack of demand for field this operation of young people and the rapid increase of migration to big
