Ill ABSTRACT Ph.D. Thesis ECOLOGICAL STUDIES WITH AN EMPHASIS ON THE POPULATION FLUCTUATIONS AND HOST RELATIONS OF BIG BUD MITES [Phytocoptella avellanae (Nal.) and Cecidophyopsis vermiformis (Nal.) (Eriophyoidea: Acarına)] ON FILBERT IN BLACK SEA REGION Sebahat KEÇECİ ÖZMAN Ankara University Graduate School of Natural and Applied Sciences Department of Plant Protection Supervisor: Prof.Dr. Seval TOROS 1995, Page: 186 Jury: Prof.Dr. Seval TOROS Prof.Dr. Neşet KILINÇER Prof.Dr. Osman ECEVİT In this study performed in the Blacksea Region in 1992-1994, life cycles, population fluctuations, seasonal populations of the species in the big buds in which two species were found together, damage types, damage rates, natural enemies, prevalence of P. avellanae and C. vermiformis and resistant and sensitive hazelnut cultivars against these mites were investigated. It was found that P. avellanae had a simple life cycle, nymphae migrated towards healty buds, fed and reproduce in these buds and that generations interfered in each other. It was determined that vagrant form of P. avellanae had a rather complex and different life cycle from P. avellanae. They survive on the vegetative and generative buds and in big buds, continue feeding and reproducing during the year. In addition it was observed that they had two types of nymphae. It was found that C. vermiformis had also a complex life cycle and had two migration periods on spring and autumn. It was determined that they lived inside the buds with P. avellanae and their generations interfered in each other. Besides, C. vermiformis individuals living on generative and vegetative buds were seen.IV Although the number of P. avellanae on newly infested buds was very low in early summer, it was found that they reached maximum population level in the following spring. C. vermiformis inside the summer buds reached the maximum population level in the early autumn while those inside the winter buds reached the maximum level in spring. It was found that C. vermiformis was the dominant species with the beginning of July while the populations of two species were approximately equal in the summer buds in which the both species were found. It was observed that C. vermiformis populations were usually dominant in the spring although the number of C. vermiformis individuals entering into the buds in the autumn was very low in winter. It was determined the P. avellanae caused big bud formation only on the generative buds and didn't cause any damage on the vegetative buds and that vagrants didn't cause the formation of big bud, but they caused dropping of buds and deformations of various plant tissues. It was found that C. vermiformis didn't cause big bud formation but lived inside the big buds formed by P. avellanae. C. vermiformis individuals feeding on vegetative and generative buds were observed. Infested buds which were very small in the early summer, reached maximum size in the next spring. It was found that there was a lineer relation between big bud size and mite population. It was determined that big buds especially develop on the apical buds of the short shoots and in the middle buds of long shoots. All the buds were not infested with C. vermiformis. It was determined that the number of buds infested with P. avellanae were more than the buds infested with the both mites. Damage rates were different between cultivars. It was found that populations of phytoseid mites Amblyseius aberrans Oudemans and Phytoseiulus macropilis (Banks) were high in the buds. Among the hazelnut cultivars, Tombul and Mincane were found as the most susceptible cultivars, while Acı, Kuş and Palaz were the resistant ones.
