Apis florea is a single-combed, open-nesting, dwarf honeybee indigenous to Asia. In common with other species of this genus, A. florea is highly polyandrous, and is therefore predicted to curtail worker reproduction by mutual policing mechanisms that keep worker reproduction at an extremely low level. Policing mechanisms could involve destruction of workers' eggs or offspring, or aggression toward those workers that are reproductively active. We show that in A. florea, worker-laid eggs are eliminated approximately twice as fast as queen-laid eggs, indicating that A. florea uses oophagy of worker-laid eggs as a mechanism of worker policing. Genetic analysis of four colonies indicated that all males produced were sons of queens, not workers. Dissections of 800 workers, from four colonies, did not reveal any significant levels of ovary activation. These results suggest that worker policing is an effective component of the mechanisms that maintain worker sterility in this species. Furthermore, they suggest that worker policing via oophagy of worker-laid eggs is pleisiomorphic for the genus. 相似文献

All honeybee species make use of the waggle dance to communicate the direction and distance to both food sources and potential
new nest sites. When foraging, all species face an identical problem: conveying information about profitable floral patches.
However, profound differences in nesting biology (some nest in cavities while others nest in the open, often on a branch or
a cliff face) may mean that species have different requirements when dancing to advertise new nest sites. In cavity nesting
species, nest sites are a precise location in the landscape: usually a small opening leading to a cavity in a hollow tree.
Dances for cavities therefore need to be as precise as possible. In contrast, when the potential nest site comprises a tree
or perhaps seven a patch of trees, precision is less necessary. Similarly, when a food patch is advertised, dances need not
be very precise, as floral patches are often large, unless they are so far away that recruits need more precise information
to be able to locate them. In this paper, we study the dance precision of the open-nesting red dwarf bee Apis florea. By comparing the precision of dances for food sources and nest sites, we show that A. florea workers dance with the same imprecision irrespective of context. This is in sharp contrast with the cavity-nesting Apis mellifera that increases the precision of its dance when advertising a potential new home. We suggest that our results are in accordance
with the hypothesis that the honeybees’ dance communication initially evolved to convey information about new nest sites and
was only later adapted for the context of foraging. 相似文献

The Red Dwarf honeybee (Apis florea) is one of two basal species in the genus Apis. A. florea differs from the well-studied Western Hive bee (Apis mellifera) in that it nests in the open rather than in cavities. This fundamental difference in nesting biology is likely to have implications
for nest-site selection, the process by which a reproductive swarm selects a new site to live in. In A. mellifera, workers show a series of characteristic behaviors that allow the swarm to select the best nest site possible. Here, we describe
the behavior of individual A. florea workers during the process of nest-site selection and show that it differs from that seen in A. mellifera. We analyzed a total of 1,459 waggle dances performed by 197 scouts in five separate swarms. Our results suggest that two
fundamental aspects of the behavior of A. mellifera scouts—the process of dance decay and the process of repeated nest site evaluation—do not occur in A. florea. We also found that the piping signal used by A. mellifera scouts to signal that a quorum has been reached at the chosen site, is performed by both dancing and non-dancing bees in
A. florea. Thus, the piping signal appears to serve a different purpose in A. florea. Our results illustrate how differences in nesting biology affect the behavior of individual bees during the nest-site selection
process. 相似文献

The dwarf honeybees Apis florea and Apis andreniformis are sympatric in Southeast Asia. We examined undisturbed nests of both species finding that heterospecific workers are present
in some nests at low frequency. This suggested that workers may enter heterospecific nests as a prelude to reproductive parasitism.
To test this hypothesis, we created mixed-species colonies and determined the reproductive response of workers within them
based on molecular markers. In queenless colonies, workers of both species activated their ovaries at equal frequency. However,
the majority species, A. florea, had complete reproductive dominance over A. andreniformis, most likely because the A. florea workers recognised and removed heterospecific larvae. In queenright mixed-species colonies, workers responded to heterospecific
signals of the presence of the queen and did not activate their ovaries. Thus, despite predictions from kin selection theory
that workers would benefit from parasitising heterospecific nests, we find no evidence that selection has established a parasitic
strategy in these sibling species. 相似文献

Workers of the Asian hive bee, Apis cerana, are shown to have relatively high rates of worker ovary activation. In colonies with an active queen and brood nest, 1-5% of workers have eggs in their ovarioles. When A. cerana colonies are dequeened, workers rapidly activate their ovaries. After 4 days 15% have activated ovaries and after 6 days, 40%. A cerana police worker-laid eggs in the same way that A. florea and A. mellifera do, but are perhaps slightly more tolerant of worker-laid eggs than the other species. Nevertheless, no worker's sons were detected in a sample of 652 pupal males sampled from 4 queenright colonies. A cerana continue to police worker-laid eggs, even after worker oviposition has commenced in a queenless colony. 相似文献

We studied nest site selection by swarms of the red dwarf honeybee, Apis florea. By video recording and decoding all dances of four swarms, we were able to determine the direction and distances indicated
by 1,239 dances performed by the bees. The bees also performed a total of 715 nondirectional dances; dances that were so brief
that no directional information could be extracted. Even though dances converged over time to a smaller number of areas, in
none of the swarms did dances converge to one site. As a result, even prior to lift off, bees performed dances indicating
nest sites in several different directions. Two of four swarms traveled directly in what seemed to be the general direction
indicated by the majority of dances in the half hour prior to swarm lift off. The other two traveled along circuitous routes
in the general direction indicated by the dances. We suggest that nest site selection in A. florea has similar elements to nest site selection in the better-studied Apis mellifera. However, the observation that many more locations are indicated by dances prior to lift off also shows that there are fundamental
differences between the two species. 相似文献
