-The Japanese honeybee, Apis cerana japonica , is regarded as an important pollinator of crops and wild flowers. On the other hand, its gnawing behaviour on lettuce Lactuca spp. results in serious damage to the crop yield. Little is known about the gnawing behaviour of A. c. japonica . In the present study, field experiments were conducted to clarify the seasonality of this behaviour and the preference of A. c. japonica toward lettuce. The rates of lettuce damage by gnawing differed among furrows, and the maximum rate was 17 %, while A. c. japonica showed no preference according to lettuce type. The rate of gnawing behaviour on lettuce 31 days from seeding was significantly higher than that on lettuce at 20 days. Lettuce gnawing of A. c. japonica was not confirmed in spring but was seen in autumn, while there was no visitation to the lettuce by the European honeybee, Apis mellifera . These results suggested that A. c. japonica might require substances produced by lettuce in autumn for overwintering.

“…Comparative information about alarm pheromone responses from multiple bee species is necessary to understand alarm pheromone evolution. In addition, A. dorsata is widespread throughout Asia (Oldroyd and Wongsiri, 2006;Hepburn and Radloff, 2011), where it is an important pollinator of crops (Wongsiri et al, 2001;Partap, 2011) and native plants (Corlett, 2011). Finally, A. dorsata is sympatric with two other native Apis species with which it shares alarm pheromone components (Boch et al, 1962;Morse et al, 1967;Koeniger et al, 1979) and, potentially, alarm information.…”

Social pollinators such as honey bees face attacks from predators not only at the nest, but also during foraging. Pollinating honey bees can therefore release alarm pheromones that deter conspecifics from visiting dangerous inflorescences. However, the effect of alarm pheromone and its chemical components upon bee avoidance of dangerous food sources remains unclear. We tested the responses of giant honey bee foragers, Apis dorsata, presented with alarm pheromone at a floral array. Foragers investigated the inflorescence with natural alarm pheromone, but 3.3-fold more foragers preferred to land on the 'safe' inflorescence without alarm pheromone. Using gas chromatography-mass spectrometry analysis, we identified eight chemical components in the alarm pheromone, of which three components (1-octanol, decanal and gamma-octanoic lactone) have not previously been reported in this species. We bioassayed six major compounds and found that a synthetic mixture of these compounds elicited behaviors statistically indistinguishable from responses to natural alarm pheromone. By testing each compound separately, we show that gamma-octanoic lactone, isopentyl acetate and (E)-2-decen-1-yl acetate are active compounds that elicit significant alarm responses. Gamma-octanoic lactone elicited the strongest response to a single compound and has not been previously reported in honey bee alarm pheromone. Isopentyl acetate is widely found in the alarm pheromones of sympatric Asian honey bee species, and thus alarmed A. dorsata foragers may produce information useful for conspecifics and heterospecifics, thereby broadening the effects of alarm information on plant pollination.

“…In the heavily infested areas, a decrease in the Japanese honeybee population due to overwinter death is a concern. The Asian honeybee A. cerana plays an important role in the pollination of various crops and natural flora and enhances the vibrancy of floral diversity and agricultural productivity (Partap 2011). Japanese honeybees also visit various plant taxa and utilize their pollen (Nagamitsu and Inoue 1999).…”

Tracheal mites, Acarapis woodi, greatly increase overwinter mortality in colonies of the Japanese honeybee, Apis cerana japonica

-This study evaluated the damage caused by the tracheal mite Acarapis woodi to colonies of the Japanese honeybee Apis cerana japonica , by investigating mite prevalence and colony death of the honeybees during winter. Honeybees of 114 colonies were sampled from October to December to detect mite prevalence. The colony death was monitored up to the end of April. The observed mortality due to mite infestation was compared with data from two previous studies about European honeybees. Under normal conditions in the absence of mites, 21 % of intact colonies died during the winter season. However, once the honeybee colonies were infested with A. woodi , the overwinter mortality was drastically increased. The mortality of Japanese honeybee colonies infested with the tracheal mites was higher than that reported historically in European honeybee colonies infested with the mites. Investigation of colony mortality at the apiary level showed that mortality was significantly higher in miteinfested than non-infested apiaries, but there were no significant differences related to the estimated winter air temperature. These results suggest that tracheal mite infestation seriously increases the overwinter mortality of Japanese honeybees.Asian honeybee / tracheal mite / colony death / overwinter mortality
