Abstract. Bareke T, Addi A. 2019. Bee flora resources and honey production calendar of Gera Forest in Ethiopia. Asian J For 3: 69-74. Gera forest contains substantial coverage of natural forest and known as a Key Biodiversity Hotspot area for Coffea arabica conservation and one of the potential areas for beekeeping. The study was carried out to assess the bee flora and flowering calendar to harvest more honey following the flowering plant cycle. Semi-structured questionnaires, participatory Rural Appraisal (PRA) techniques, and field observation were used for data collection. Honey samples collection was also made to identify the botanical origin of honey through honey pollen analysis. Seventy-four bee plant species were identified, which belongs to 41 families. Among the identified plant families, Asteraceae (29.3%), Lamiaceae (14.6%), Acanthaceae (12.2%), and Fabaceae (9.8%) are the most frequent families, represented by the highest species composition in the area. Four major honey harvesting durations were identified (January, March, April, and early June for Vernonia, Coffee, Schefflera, and Croton honey respectively) using the flowering calendar in Gera Forest. The pollen analysis of honey revealed that four types of monofloral honeys were identified comprising Schefflera abyssinica, Vernonia amygdalina, C. arabica and Croton macrostachyus in Gera forest. This is due to their abundance and potentiality for honey production. Therefore, the beekeepers should follow the flowering calendar of the plant to exploit the potential of the forest for honey production. Furthermore, market promotion for monofloral honeys of the Gera forest should be made as an incentive for the beekeepers to sell honey with premium prices and branding and labeling of honey of the area

Abstract. Addi A, Bareke T. 2019. Review: Floral resources diversity and vegetation types important for honeybees in Ethiopia. Asian J For 3: 64-68. The high biodiversity of Ethiopia is attributed to its wide range of altitude and great geo-morphological diversity. This has resulted in the existence of a high diversity of floral resources of which majority of them are visited by honeybees. This paper aimed to review existing studies on bee floral resources in Ethiopia to understand the types of bee plants, floral diversity, flowering period and food source offered by the plants. Over 1500 species of indigenous and exotic plants belonging to 105 bee plant families have been identified. The growth form of bee forage comprises 41.6% herb, 28.7% shrubs, 21.7% trees, and 8% climbers. The majority of bee plant species flower from September to November and April to May, resulting in two major honey flow periods in the country. From this information, Ethiopia has rich bee forage diversity across different vegetation types, however, further collection and documentation of bee flora are required in unaddressed areas of the country. Thus in situ conservation by ecological restoration, and raising and planting of seedlings of bee forages should be promoted for sustainable honey production.

AbstractNineteen samples of honey were collected from different localities of the Borana Zone and examined to identify the botanical origin of honey through honey pollen analysis. From nineteen honey samples, sixteen were identified as monofloral honeys. Twentyeight plant species were identified as honey source plants and the identified plant species belonged to fourteen plant families. Out of twenty-eight bee plant species, 17.9% of them were found in the Fabaceae family followed by Asteraceae and Lamiaceae, each of them accounting for 14.3% of all honey plants species found in the samples. The Shannon-Wiener diversity index (H) showed that high diversity of plant species was found in eleven honey samples with a range of 1.07 (Bule Hora site 1) to 1.81 (Yabello site 2) on the basis of honey pollen analysis. Eight honey samples had lower diversity index values, ranging from 0 (Arero site 2 and Bule Hora site 3) to 0.84 (Gelana site1), which suggests the honey was obtained from a few dominant plant species. Accordingly, Guizotia scabra, Haplocoelum foliolosum, Plectranthus assurgens, Terminalia brownii, Sesamum indicum, Satureja paradoxa, Croton macrostachyus and Acacia brevispica were the major monofloral honeys produced from the area. This indicates that there is a huge potential for the production of monofloral honey. Since monofloral honey has a good market value and is preferred by consumers, the involvement of investors is recommended.

The Amaryllidaceae features prominently amongst bulbous flowering plant families. Accommodating about a third of its species, South Africa affords a sound basis for Amaryllidaceae plant research. Boophone, Nerine, Crossyne, Clivia, Cryptostephanus, Haemanthus and Scadoxus have been well-represented in such endeavors. The account herein summarizes the studies undertaken between 2013-2020 on these genera in regards to their chemical and biological characteristics. A total of 136 compounds comprising 63 alkaloids and 73 non-alkaloid entities were described during this period from eighteen members of the title genera. The alkaloids were reflective of the structural diversity found in eight isoquinoline alkaloid groups of the Amaryllidaceae. Of these, the crinane (29 compounds), lycorane and homolycorine (11 compounds each) groups were the most-represented. The non-alkaloid substances were embracive of the same number of unrelated groups including, acids, phenolics, flavonoids and triterpenoids. A wide variety of assays were engaged to ascertain the biological activities of the isolated compounds, notably in regards to cancer and motorneuron-related diseases. There were also attempts made to determine the antimicrobial, anti-inflammatory and antioxidant effects of some of the substances. New information has also emerged on the herbicidal, insecticidal and plant growth regulatory effects of selected alkaloid principles. Coupled to the biological screening measures were in instances probes made to establish the molecular basis to some of the activities, particularly in relation to cancer and Parkinsonʹs disease.

Abstract The study was conducted in two purposefully selected zones of Oromiya Regional State, namely Jimma and Illubabor. The objective of the study was to analyse the honey-bee production and to assess hive technology preferences in the study area. A total of 156 beekeepers were randomly and proportionately selected from four districts (Mana and Gomma from Jimma and Bacho and Yayo from Illubabor). Data were collected through formal survey and secondary sources. Accordingly, the average age of the beekeepers was 40.2 ± 8.13 years with an average of 13.5 ± 6.58 years of experience. The majority of the respondents (53.2%) in the study area got their colonies by catching swarms. Three hive types (traditional, transitional, and frame hive) were found in the study area. More than 70% of the respondents harvested once a year from traditional hives, while 25% of respondents harvested up to three times per year from frame hives. Moreover, an average of 22 ± 4.6 and 16 ± 4.1 kg of honey were harvested from frame and transitional hives per year, respectively. Compared to these two hives, a much lower (7 ± 1.6 kg) amount of honey was harvested from traditional hives. Various honey-bee floras were identified in the study area. Plants such as Vernonia amygdalina, Croton macrostachyus, and Schefflera sp. produce white honey. Half of the respondents’ preferred transitional hive followed by frame hive (37.2%). Factors which affect the use of frame hives were lack of equipment (36.5%) followed by wax quality and availability problems (34%). That is why few beekeepers tried to modify the frame hive to solve the problems of wax in vertical frame hive. In order to adopt and sustain modern hive technology, the focus should be on honey-bee equipment as well as wax quality and availability.

Volume Decrease

Nectar concentration is assumed to remain constant during transport by honeybees between flowers and hive. We sampled crop contents of nectar foragers on Aloe greatheadii var. davyana , a major winter bee plant in South Africa. The nectar is dilute (approx. 20% w/w), but the crop contents of bees captured on flowers are significantly more concentrated. In returning foragers, the concentration increases further to 38–40%, accompanied by a volume decrease. The doubling of sugar concentration suggests that nectar is regurgitated onto the tongue and evaporated during foraging and on the return flight. Processing of the dilute nectar into honey thus begins early, aided by low ambient humidities. This has implications for honeybee thermoregulation, water balance and energetics during foraging, and for the communication of nectar quality to recruits.
