Migrating Giant Honey Bees (Apis dorsata) Congregate Annually at Stopover Site in Thailand

Giant honey bees (Apis dorsata) of southern Asia are vital honey producers and pollinators of cultivated crops and wild plants. They are known to migrate seasonally up to 200 km. It has been assumed their migrations occur stepwise, with stops for rest and foraging, but bivouacking bees have rarely been seen by scientists. Here I report discovery of a site in northern Thailand where bivouacs app...

Intraspecific Aggression in Giant Honey Bees (Apis dorsata)

We investigated intraspecific aggression in experimental nests (expN₁, expN₂) of the giant honey bee Apis dorsata in Chitwan (Nepal), focusing on interactions between surface bees and two other groups of bees approaching the nest: (1) homing "nestmate" foragers landing on the bee curtain remained unmolested by guards; and (2) supposed "non-nestmate" bees, which were identified by their erratic ...

Properties and Antimicrobial Activity of Apis Dorsata Honey from Thailand

Objectives: For Apis dorsata honey, the basic properties, namely the pH, and the total proline, protein and invert sugar contents, were determined. For proteins, the mass weight and partial amino acid sequence of the three major proteins were assayed and homologs screened for. A bioassay for antimicrobial activity was also performed. Methodology: Proline content and the percentage of invert sug...

The Sex Determination Gene Shows No Founder Effect in the Giant Honey Bee, Apis dorsata

BACKGROUND All honey bee species (Apis spp) share the same sex determination mechanism using the complementary sex determination (csd) gene. Only individuals heterogeneous at the csd allele develop into females, and the homozygous develop into diploid males, which do not survive. The honeybees are therefore under selection pressure to generate new csd alleles. Previous studies have shown that t...

Sucrose responsiveness and behaviour in honey bees (Apis mellifera L.)

In dieser Arbeit wird bei der Honigbiene (Apis mellifera L.) analysiert, wie sich die individuelle Empfindlichkeit für Zuckerwasserreize auf verschiedene Formen der Verhaltensplastizität auswirkt. Die Versuche klären insbesondere die Rolle des Belohnungsreizes Zuckerwasser beim assoziativen und nicht-assoziativen Lernen auf. In den Untersuchungen werden Bienen verschiedenen Genotyps, verschiede...
