Abstract
Honeybees
are the most numerous and significant among insect pollinators, but despite their significance their
potential role in increasing the reproductive success of threatened European
orchids remains largely unexplored. In this study we
aim to evaluate the effect of apiary proximity on the fructification rate of
the rare and endangered Adriatic Lizard Orchid (Himantoglossum adriaticum
H. Baumann). To do so, first we
quantified the reproductive success (fruit set) of the Adriatic Lizard Orchids
in a Hungarian population in close proximity to a honeybee apiary at Nagytevel.
Then we compared the reproductive success in this population to the
reproductive success in 3 other Hungarian, 4 Croatian populations (observed
during the same year, 2013) and further 4 populations from Hungary (studied in
previous years, 1992–2011) with no apiaries in the close proximity of these. The
realised 61.7 % fruit set at Nagytevel is the highest reproductive success ever
recorded for this species. The importance of apiaries is further emphasised by
the fact that the reproductive
success of Lizard Orchid individuals decreased significantly with increasing
distance from the apiary. Our results provide empirical support for the
conservation importance of apiculture and suggests promising results for
practical application of apiaries in the conservation of of deceptively pollinated orchids characterised by
lower fruit set (e.g. Orchis, Anacamptis, Himantoglossum).
