The honeybee waggle dance, through which foragers advertise the existence and location of a food source to their hive mates, is acknowledged as the only known form of symbolic communication in an invertebrate. However, the suggestion, that different species of honeybee might possess distinct 'dialects' of the waggle dance, remains controversial. Furthermore, it remains unclear whether different...

Apis mellifera jemenitica Ruttner (= yemenitica auctorum: videEngel 1999) has been used in apiculture throughout the Arabian Peninsula since at least 2000 BC. Existing literature demonstrates that these populations are well adapted for the harsh extremes of the region. Populations of Apis mellifera jemenitica native to Saudi Arabia are far more heat tolerant than the standard races often import...

objective(s):previous studies demonstrated a functional similarity between vertebrate and honey bee nervous systems. the aim of the present study was to compare the effects of heroin and iranian street kerack, a combination of heroin and caffeine, on sensory threshold and locomotor activity in honey bees. materials and methods: all drugs were given orally to honey bees 30 min before each experi...

b a ckground: the varroa destructor mite is considered as a major pest of honey bees apis mellifera . the rapid spread of varroa mites among bee colonies may be due to several factors, including drifting of infested bees, movement of bee swarms, and robbing of weakened colonies. disease spread and predisposing the infested bees to other diseases lead to high economic losses in beekeeping indust...

Abstract In honeybees, the mechanism of sex determination depends on genetic variation at complementary determiner ( CSD ) locus, which has a large allelic diversity. this study, we examined population structure and diversity within highly variable region HVR in five Apis mellifera subspecies, addition to Buckfast unknown mixed ancestry bees. We sequenced 329 drones, 146 from Algeria A. m. inte...

Bees of the genus Apis are important foragers of nectar and pollen resources. Although the European honeybee, Apis mellifera, has been well studied with respect to its sensory abilities, learning behaviour and role as pollinators, much less is known about the other Apis species. We studied the anatomical spatial resolution and absolute sensitivity of the eyes of three sympatric species of Asian...

Rearing techniques are important to determine a successful honey bee production. Queen cell cup size may affect the acceptance rate of grafted larvae and queen’s size, which in turn influence quality colonies. The present study compared effect different queen sizes (8.0 vs 9.0 mm diameter) on morphometric characteristics bees. Sixty-five were each treatment. Larvae transfer was carried out five...

Apis mellifera venom is one of the best characterized venoms among Hymenoptera, yet relatively little is known about venom belonging to other species in the genus Apis. Melittin, one of the most important bioactive peptides, has been isolated and characterized in A. mellifera, Apis cerana, Apis dorsata and Apis florea, while apamin has been only characterized in A. mellifera and A. cerana. At p...

Nosema diseases is known to have two infecting Apis mellifera, Nosema apis and Nosema ceranae. Historically N. apis was known to be well established pathogen of A. mellifera. Whoever N. ceranae was frequently reported to infect the honeybees during the last decade. Both N. apis and N. ceranae are now thought to be widespread across the world. Honey bees are also found to be co-infected with bot...
