This was a great honour to Hungary because it has been a sign of recognition of the pollination research being made in this country. The Sympo­sium was the 8th world conference on pollination ecology as a part of a series of international symposia held first in Copenhagen, Den­mark (1960), thereafter in London, UK (1964), Prague, Czechoslova­kia (1974), University of Mary­land, USA (1978), Versailles, France (1983), Tilburg, The Ne­therlands (1990), and Lethbridge, Alberta, Canada (1996). The 8th meeting was organised under the auspices of the International Com­mission of Plant Bee Relationships (ICPBR), a scientific member of the International Union for biolo­gical Sciences and it was a great pleasure that the International So­ciety for Horticultural Science (ISHS) also accepted the Symposi­um as its official scientific meet­ing. The international recognition of the insect pollination research in Hungary, however, goes back over a long period, since it was initiated with studies on the pollinating wild bees of Lucerne when Z. Boj­tos, a plant breeder, encouraged an entomologist, L. Móczár, to study the problem in the mid-fifties. The specific structure and the density of Lucerne pollinating wild bees as well as their flower visiting and tipping speed on Lucerne were dis­covered. This research was conti­nued and developed in Hungary by P. Benedek in the late sixties who discovered that there were some typical flight period patterns among wild bees and each of them represented a separate group of species having been adapted to dif­ferent sections of the seasonal suc­cessions of the blooming flora. He also discovered the relationship of wild bees to Lucerne and other available pollen sources. The ef­fect of different environmental conditions on the density and the specific structure of wild bee po­pulations in Lucerne fields was also studied in detail and the long term impact of a changing agricul­ture on the specific structure and the density of wild bees pollinating Lucerne was also recognised. Later on he also studied the polli­nating wild bees of cultivated vet­ches as well as of red clover. In the early seventies bee pollination stu­dies of P. Benedek and his research team were extended to other field crops also, including winter rape, sunflower and seed onion, and also some studies were made with some fruit tree species and small fmits. As a result of these studies a book was written on the “Pollinati­on of Crops by Honeybees” (Meg­­porzás mézelő méhekkel, 1974, authors: Benedek - Manninger - Virányi) as a synthesis of the world literature and the results of the re­search made in Hungary. Trials were made to solve the propagati­on of the Lucerne leaf cutting bee in Hungary by S. Manninger in the seventies and also the nest parasi­tes of this wild bee species were investigated in Hungary. Intensive research on the bee pollination of fruit crops was initi­ated by P. Benedek, J. Nyéki and M. Sotész in the late seventies. They established a fruit tree polli- Continued on page 22. Figure 1.
