A comparison of the poisoning incidents in honeybee populations in Germany from 1996 to 1998 shows that the damages mainly had been distributed to three cultures: fruits and potatoes in 1996, rape in 1997 and 1998. The clarification of the incidents showed that there had been a main reason for the poisoning in each culture and year. The incidents in fruit cultures of 1996 were caused by the misuse of Fenoxycarb at the beginning flowering period and the incidents in potatoes were caused by the application of organophosphorous compounds to honeydew. The incidents in rape in 1997 and 1998 were caused by a combination of Pyrethroids classified as not hazardous for bees with fungicides of the group of Ergosterol-Biosynthesis-Inhibitors (EBI). The development of the incidents show that poisoning incidents may always arise in cultures, where they are not expected. An actual and complete information of the farmers by the plant protection service and a correct promotion for the products by the approval holders may prevent a great part of the incidents. An overview about the long-term development of the poisoning incidents in Germany shows that the number of incidents in the years 1996 to 1997 remained an a low level with less than 100 incidents per year and this will continue in 1999 too. In contrast to this the number of honeybee populations has slightly increased up to 1.05 Mio populations. Overall it must be stated that the number of incidents by deliberate poisoning is too high and that the number of incidents to which there is no further information on the reason seems to be increasing
