“…The correct name for this compound is (E)-2-decen-1-yl acetate (J. Millar, personal communication). Veith et al (Veith et al, 1978) first discovered this compound in A. dorsata and A. florea workers, and in both species it elicits aggression when placed on a bait near the nest (Koeniger et al, 1979). Our study tested forager responses, and (E)-2-decen-1-yl acetate repelled foragers from landing on an inflorescence (Table 3, Fig.…”

“…(E)-2-decen-1-yl acetate Blum et al (Blum et al, 2000) reported that the major component of sting shaft extracts of A. dorsata workers was 1-acetox-2-decene [synonymous with the 2-decen-1-yl acetate reported by Koeniger et al (Koeniger et al, 1979) and Veith et al (Veith et al, 1978)].

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.

“…However, the production of eicosenol is vastly reduced (A. florae and A. andreniformis) or completely absent (A. dorsata) in these species. It appears that another compound decenyl-acetate has replaced the function of eicosenol in these species as it has been found in the stings of A. dorsata and A. florae (Veith et al, 1978). We did detect 2-decen-1-yl-acetate in the dried stings of A. andreniformis, A. dorsata and A. florae workers but not in A. mellifera, A. cerana or A. koschevnikovi.…”

“…The role of eicosenol in A. mellifera seems to extend the activity of isopentyl acetate and increase the speed of a defensive response (Koeniger et al, 1979). However, in A. florea and A. dorsata a different low-volatile substance 2-decen-1-yl-acetate appears to perform a similar function to eicosenol (Veith et al, 1978;Koeniger et al, 1979).…”

Setosa membrane structure and occurrence of eicosenol in honeybees (Apissp.)

-Morphological analysis showed that the setosa membrane of workers is reduced in Apis cerana and A. koschevnikovi in comparison to that of A. mellifera. This may be due to different predator pressures among these species. This finding is supported by the marked reduction in the amount of the alarm pheromone eicosenol detected on the sting apparatus (setose area) in A. cerana workers in relation to that found in A. mellifera workers. The setosa membranes of the three open nesting species, A. andreniformis, A. florae and A. dorsata are well developed despite eicosenol being completely absent in A. dorsata and present in only trace amounts in A. florea and A. andreniformis workers. We also confirm that during dissection the internal glands of the sting apparatus do not become contaminated with compounds such as eicosenol, which can be present on the sting surface in high concentrations.honeybee / eicosenol / Dufour gland / defence / alarm pheromone
