TL;DR: Analysis of the honey produced in hives as well as the stored pollen loads help to evaluate the sources of nectar and pollen used by honey bees and their behavioural pattern in the selection of preferences for certain plants as food.
Abstract: Gathering information on the bee foraging plants in a given area is of primary importance in the development of any apiculture industry. Analysis of the honey produced in hives as well as the stored pollen loads help to evaluate the sources of nectar and pollen used by honey bees and their behavioural pattern in the selection of preferences for certain plants as food. Our previous melissopalynology study focused on the analysis of the Omani honey from hives in 14 locations of Muscat and the Al Batinah regions. Our current study examines the pollen pellets collected from those same areas. A total of 249 pollen pellets from 22 honeycombs that were collected by Apis florea and Apis mellifera honeybees were processed and the pollen types were identified using light and scanning electron microscopy. Each pollen load was designated as a unifloral, bifloral or multifloral type. Each plant taxon identified was categorized as being utilized by honeybees for pollen only, nectar only or for both pollen and nectar. A...

TL;DR: Apis florea took an inadvertent leap onto the African continent and was detected in Khartoum, Sudan, for the first time in 1985 and has been gradually expanding its territory to the whole of Sudan and to neighbouring countries.
Abstract: Apis florea took an inadvertent leap onto the African continent and was detected in Khartoum, Sudan, for the first time in 1985 (Lord & Nagi 1987; Mogga & Ruttner 1988). The occurrence of these bees in Africa is very likely via global transportation. Since then, A. florea has been gradually expanding its territory to the whole of Sudan (Moritz et al. 2010) and to neighbouring countries. Moreover, in Asia A. florea has been steadily expanding westwards, and it is now well established in the Middle East (Hepburn et al. 2005; Haddad et al. 2009).

TL;DR: It can be concluded that body weight and morphometric characteristics of dwarf honey bee workers were significantly affected by geographic origin.
Abstract: a b s t r a c t here we performed a morphometric analysis of dwarf honey bee ( apis florea f.) workers from saudi arabia, and we detected morphometric variations within the species in the Jubail and al-ahsa provinces of this region. between the two provinces, Jubail is further north and is closer to sea level, and data showed that during the collection period, Jubail experienced significantly higher humidity. compared to workers from the Jubail province, workers from al-ahsa province showed significantly higher body weight, measured head appendage characteristics, wing characteristics (apart from hindwing width), leg characteristics, and length and width of the 3 rd abdominal sternite and 1 st wax mirror. body weight as found to be significantly positively correlated with all determined characteristics, except for flagellum length, hindwing width, 3 rd tergite length, and lengths of the 4 th tergite and sternite. it can be concluded that body weight and morphometric characteristics of dwarf honey bee workers were significantly affected by geographic origin. the morphometric measurements were within the range reported from most previously examined countries.

TL;DR: Field investigations were carried out to determine the diversity and relative abundance of various honeybee species during 2011 and 2012 and found the majority of specimens were from Apis cerana F. cerana, which is found in most parts of Pakistan but no specimen was observed in the study area.
Abstract: Field investigations were carried out to determine the diversity and relative abundance of various honeybee species during 2011 and 2012. Total 184 samples were collected from 10 different localities in Murree and its vicinity. The majority of specimens (n=156, 84.78%) were from Apis cerana F. The ratio of Apis mellifera L. was 13.04% (n=24) and only 2.17% (n=4) honeybees belonged to Apis dorsata F. Although Apis florea F. is found in most parts of Pakistan but no specimen was observed in the study area.

TL;DR: In this article, an ultrastructural study on the antenna of two open-nesting worker honey bees was conducted and the results showed that the antennal form as well as the sensilla arrangement was adapted to the pheromone perception need of regarding a particular species.
Abstract: Antenna of honey bees is geniculate and has been known to possess a wide variety of sensilla. The sensilla are sensitive to odor, temperature, humidity, air pressure and gustatory stimuli. In the present investigation, ultrastructural study on the antenna of the two open-nesting worker honey bees- Apis florea F. - the dwarf honey bee and A. dorsata F. - the giant honey showed considerable amount of variation in the types and distribution pattern of sensilla in the two species. The antennal form as well as the sensilla arrangement has been suggested to be adapted to the pheromone perception need of regarding a particular species.

TL;DR: Studies on the pollination efficiency of honey bees in sunflower (Helianthus annuus L.) revealed that the seeds/ capitulam, 1000 seeds weight, and % crinkled seeds were maximum in six framed Apis mellifera pollinated crop followed by one colony of Apis floreapollinated crop.
Abstract: Studies on the pollination efficiency of honey bees in sunflower (Helianthus annuus L.) revealed that the seeds/ capitulam (1278), 1000 seeds weight (47.3), and % crinkled seeds (8.2) were maximum in six framed Apis mellifera pollinated crop followed by one colony of Apis florea pollinated crop. The six framed Apis mellifera yield in (16.4q /ha -1 ), one colony of Apis florea (15.0 q /ha -1 ), and% seed setting in Apis mellifera (86.9%) crop was significantly higher over the pollination without insects. Although six framed Apis mellifera pollinated crop was statistically at par with one colony of Apis florae pollinated crop but the % of germination was significantly in higher six framed Apis mellifera (94.3%) followed by open pollination (93.5%)

TL;DR: Catecholamines were quantified from an extract of the venom gland and reservoir of three honey bee species using liquid chromatography with electrochemical detection, showing that the quantity of each amino acid in the venoms differed between bee species.
Abstract: SummaryCatecholamine systems play a variety of roles in animals as neurotransmitters, neuromodulators, hormones, paracrine and autocrine factors. Many venoms of widely different animals have evolved to manipulate these systems for both defensive and offensive purposes. Catecholamines are sympathomimetic and comprise of a catechol group derived from the amino acid tyrosine. Physiological and anatomical evidence suggests that certain amino acids act as neurotransmitters of the major excitatory or inhibitory commands in the central nervous system, and also take part in intermediary metabolism. Catecholamines were quantified from an extract of the venom gland and reservoir of three honey bee species, Apis cerana, Apis dorsata and Apis florea using liquid chromatography with electrochemical detection (ECD). The results showed species dependent variation: 1. norepinephrine and dopamine were found in all the three Apis species, with the highest quantity in A. dorsata followed by A. cerana and the least in A. flo...

TL;DR: The success of beekeeping depends upon understanding of the biology and behaviour of honeybees, their management techniques including knowledge of their diseases and enemies for handling them.
Abstract: Asian sub continent is very rich in honeybee diversity having Indigenous honeybees (Apis cerana, Apis laboriosa, Apis dorsata, Apis florea) have co-existed through centuries and kept on going without inter specific transfer of diseases and parasites. The beekeeping is possible in all those areas which have sufficient floral resources. Among these, A. cerana is the only species that can be managed in hives, but the single combs of the other two are collected by honey hunters. The efforts have been made throughout the Asian sub continent to manage the A. dorsata and A. florea. The success of beekeeping depends upon understanding of the biology and behaviour of honeybees, their management techniques including knowledge of their diseases and enemies for handling them.

TL;DR: Results of the study conclude that, 9-ODA is a major sex pheromone component in A. cerana in contrast to 10-HDAIn A. florea queens.
Abstract: Studies were conducted on olfactory learning and memory recall in the drones of Apis cerana and Apis florea through olfactory conditioning. The results showed that, the drones of A. cerana and A. florea learn and recall olfactory memory of queen mandibular odorants, the (2E)-9-oxodecenoic acid, (9-ODA), (2E)-10-hydroxydecenoic acid (10-HDA) and (2E)-9-hydroxydecenoic acid (9-HDA). Drones of A. cerana showed greater response towards 9-ODA in contrast to A. florea drones, towards 10-HDA. However, the drones of both species responded to 9-HDA but, A. florea drones in greater numbers. Results of the study conclude that, 9-ODA is a major sex pheromone component in A. cerana in contrast to 10-HDA in A. florea queens.

TL;DR: The flowers are white sessile small zygomorphic, bilabiate,gullet shaped produced in verticils of terminal or axillary whorals and oriented horizontally to the axis.
Abstract: Leucas aspera is commonly known as Thummi chettu. The plants flower once in a year during September – February. The flowers are white sessile small zygomorphic, bilabiate,gullet shaped produced in verticils of terminal or axillary whorals and oriented horizontally to the axis. The flowers open each day during 6.00-7.30 hours. The open flowers are abundantly visited by honey bees, ants and butterflies for pollen and/ or nectar. The honey bees Apis florea, A.C indica, the digger bee Amegilla sp. Megachile sp. Anthophora zonata are the principal pollinators. During foraging visits of bees gains contact by their notaeum with essential organs and thus promote nototribic pollination. The small bodied Trigona, Ceratina, Apis florea collected pollen sternotribically.

TL;DR: In this article, the authors conducted field experiments on highly cross-pollinated melon (Cucumis melo) and watermelon (Citrullus lanatus) in order to understand how bee species with different pollination efficiencies displace each other from floral resources.
Abstract: Pollen deposition, a surrogate for bee efficiency, becomes increasingly important during their interspecific interactions. We conducted field experiments on highly cross-pollinated melon (Cucumis melo) and watermelon (Citrullus lanatus) in order to understand how bee species with different pollination efficiencies displace each other from floral resources. We observed significant displacement of less abundant but more efficient bees by the more abundant but less efficient bees in both crops, which mayleadtodeficientpollination.Wedidnotfindsignificantrelationshipof the bee displacement success and body size or abundance. Apis florea (Fabricius) and Nomia sp.2 (Latreille) had significantly more winner events in melon, while the former also had significantly more winner events in watermelon.A. florea was the only bee species that foraged mostly within the 1-m 2 virtual area after their displacement, which may indicate its behavior of geitinogamous pollination. The two bee species, Ceratina sexmaculata (Smith) and Lasioglossum sp. (Curtis), were more sensitive to displacement as their proportion of leaving the 1-m 2 virtual area was higher.

TL;DR: In the present work antibacterial activity was studied by using disc diffusion method and determined as an equivalent of the inhibition zone diameters after incubation of the culture at 37°c for twenty four hours for bacterial species.
Abstract: Three honey samples were used to study the antibacterial activity. Few gram positive and gram negative bacteria viz. Lactobacillus lactis, Staphylococcus aureus, Escherichia coli (2685 and 5051) and Pseudomonas aureginosa (5029 and 2200) were used. In the present work antibacterial activity was studied by using disc diffusion method and determined as an equivalent of the inhibition zone diameters (in millimeters) after incubation of the culture at 37°c for twenty four hours for bacterial species. Pure honey and their dilutions had good results in Staphylococcus aureus, Escherichia coli (5051) and Pseudomonas aureginosa (5029 and 2200) while pure honey and their dilutions had no effect on Lactobacillus lactis and Escherichia coli (2685).
