Colony relatedness in aggregations of Apis dorsata Fabricius (Hymenoptera, Apidae)

Summary:Apis dorsata colonies often form dense aggregations, with over 100 colonies sometimes seen in the same tree. Reasons for these aggregations are unknown, but one reasonable hypothesis is that colonies form a related family group. Here we show that 7 adjacent colonies sampled from a single branch of a tree (near Alor Setar in northern peninsular Malaysia) containing over 120 colonies were not related as mother/daughter. Thus the notion that aggregations arise through splitting of the… 

Mating frequency in Apis florea revisited (Hymenoptera, Apidae)

Effective and actual mating frequency of Apis florea queens was estimated using 92-159 worker pupae from each of five colonies, showing that the effective mating frequency is similar to that found in the rest of the genus.

Genetic structure of an Apis dorsata population: the significance of migration and colony aggregation.

The results suggest that there is significant population structuring between geographical regions, although the level of structuring caused by aggregation exceeds the differentiation attributable to geographic region.

Entomology: Giant honeybees return to their nest sites

The Asian giant honeybee Apis dorsata forms massive single-comb colonies which usually hang from a tree branch or the eaves of buildings. Although colonies regularly migrate over many kilometres, we

Genetic structure of Malaysian Apis dorsata aggregations in Marang district (Terengganu)

The genetic relatedness of A. dorsata aggregations are addressed with a preliminary study on local populations in Malaysia and showed that adjacent aggregations were genetically different and had enough time for establishing the colonies to produce honey.

Very high paternity frequency in Apis nigrocincta

The paternity frequency of A. nigrocincta is significantly higher than in all other species tested except A. dorsata and A. laboriosa, the only Apis species for which paternity frequency has not been estimated.

Genetic structure of nest aggregations and drone congregations of the southeast Asian stingless bee Trigona collina

The genetic structure of a population of 27 colonies and three drone congregations of Trigona collina in Chanthaburi, Thailand suggests that movements of drones and possibly movements of reproductive swarms among colony aggregations provide two mechanisms of inbreeding avoidance.

Genetic reincarnation of workers as queens in the Eastern honeybee Apis cerana

The appearance of queen cells in two colonies of the Eastern honeybee Apis cerana that no longer contained a queen or queen-produced brood to rear queens from are reported, the first example of thelytoky in a honeybee outside A. mellifera.

Genetic Relatedness of Low Solitary Nests of Apis dorsata from Marang, Terengganu, Malaysia

The finding of an appreciable level of intercolonial relatedness between several pairs of nests in this pioneer study indicated that a comprehensive study with a larger sample size of solitary nests found throughout the region would be necessary to provide concrete proof for the hypothesis that the honey hunters in Marang district of Malaysia repeatedly harvest the same nest located at a different site and at different time during the same honey harvesting season.

Apis dorsata Honey Hunting and Honey Trading in Mondulkiri (Eastern Cambodia)

The Asian giant honey bee, Apis dorsata F., builds its massive single comb open nest under tree branches, cliff overhangs or eaves of urban structures to follow flower blooms.

A scientific note on the mating frequency of Apis dorsata

This paper aims to demonstrate the efforts towards in-situ applicability of EMMARM, which aims to provide real-time information about the honey bees of Thailand in the summer of 2006.



Colony aggregations in Apis mellifera L.

It is likely that existing colonies attract swarms and that swarms may not always travel far from the natal nest in an environment that is replete with nesting sites.

Levels of Polyandry and Intracolonial Genetic Relationships in Apis dorsata (Hymenoptera: Apidae)

Pupae and adults of 4 Apis dorsata F. dorsata colonies from northern Thailand were collected in liquid nitrogen, and microsatellite genotypes at 3 loci determined for 42-194 workers per colony, and the queen genotype was inferred.

Spatial distribution and nesting biology of colonies of the African honey bee Apis mellifera scutellata (Hymenoptera: Apidae) in Botswana, Africa.

No differences were found between the Okavango and neotropical colonies in nest density, cavity volume, total comb area, or the proportions of comb devoted to worker brood production, food storage or drone rearing, and the aspects of nesting biology examined appear to have remained largely unchanged from the ancestral African condition during the colonization of Central and South America.

Precise assessment of the number of patrilines and of genetic relatedness in honeybee colonies

It is shown that the genetic structure of the A. mellifera colony remained largely unchanged over time as long as the colony is headed by the same queen, and the genetic diversity within the colony provided a good estimate of the genetic Diversity of the local honeybee population.

Extended survival of the parasitic honey bee mite Tropilaelaps clareae on adult workers of Apis mellifera and Apis dorsata

It is now clear that the highly pestiferous T. clareae could easily survive even the longest of international airline flights.

Biogeography and Taxonomy of Honeybees

The Genus Apis is a Polymorphic Species with an Unusual Range of Adaptation and the Races of the Near East (Irano-Ponto-Mediterranean Area).

Colony Defense Strategies of the Honeybees in Thailand

Each species' colony defense system consists of numerous interwoven lines of adaptation, including nest site, nest architecture, colony population, labor allocation to defense, age polyethism schedule, colony mobility, and worker morphology, physiology, and behavior.

Observations and Experiments on Migration and Dance Communication of Apsis Dorsata in Sri Lanka

SummaryApis dorsata has a regular annual cycle of migration in Sri Lanka. In February the colonies are spread throughout the coastal plains and the North Central Region. In June and July they migrate

Chelex 100 as a medium for simple extraction of DNA for PCR-based typing from forensic material.

The extraction of DNA from semen and very small bloodstains using Chelex 100 is as efficient or more efficient than using proteinase K and phenol-chloroform extraction and DNA extracted from bloodstain seems less prone to contain PCR inhibitors when prepared by this method.
