Shea Parklands Pollination in Burkina Faso, Some Techniques to Improve the Production

Shea tree is a major economic plant contributing to household income through the sale of edible fruits, kernels and shea butter. Shea butter is used industrially in the production of cosmetic products, chocolates and margarines. Fruits are used by human and also by birds. This study aimed to explore strategies for the improvement of shea yield through pollination. Two types of pollination (manual and natural pollination) were applied for the comparison of fruits set and their ripening. The fruits set and ripening index as well as average weight of ripe fruits and kernels were estimated. The results showed a significant difference between the fruits set Index of manual pollination and natural pollination (H(1) = 33.437, p = 7.361 × 10-9). Similarly, there was a significant difference between the ripening Index of manual pollination and natural pollination (H(1) = 4.5113, p = 0.03367). However, the mode of pollination did not influence the weight of ripe fruits and kernels. Therefore, the manual pollination enhances pollen supply to receptive stigmas for fertilization and improved fruit yield in Vitellaria paradoxa.

Adoption of Modern Bee Hive in Arsi Zone of Oromia Region: Determinants and Financial Benefits

Arsi zone is one of the Oromia regional state’s zones with high potential of honey and bees wax production and where there was dissemination of modern beehives. This research was initiated with objectives of quantifying adoption rate of modern beehives and its determinant factors and drawing policy implication for further extension of the technology. The study was conducted in seven districts of Arsi zone and 251 rural beekeepers were interviewed. The average productivity of the modern beehives and local beehives was found to be 19.77 kg/hive and 5.13 kg/hive. The total number of local bee hives possessed by interviewed beekeepers was found to be 1201 while that of modern beehives was found to be 279 hives which shows that the adoption rate is low and if we increase the adoption rate by 50%, the amount of honey harvest will increases by 11,862 kg which is about 5700 kg more than the total honey beekeepers can get from keeping the whole 1201 local hives. Chemical application (herbicides and pesticides), bee predators, lack of knowledge and skill on modern beehives, lack of modern beehive accessories, lack of bee forage and lack of capital were major beekeeping bottlenecks. The result of binary Logit model revealed that the main determinants of adoption are farmyard size, number of local hives beekeepers possessed, training provided, participation on demonstration, wealth status of beekeepers, and participation of beekeepers on nonfarm income sources. Provision of different information towards increasing or improving the saving capacity or culture of beekeepers, provision of adequate and relevant agricultural extension services (such as training on modern beekeeping technologies and experience sharing among beekeepers), provision of credit services to widen the financial bases of poor beekeepers and facilitating access to modern beehives and its accessories especially honey extractor and wax stumper which can increase beehives productivity were the recommendation that was drawn from the output of this research.

Developing Honeybee Breeding Industry to Revitalize Rural Economy

[Objectives]In Tibet,the efficiency of beekeeping industry is low,the abundant nectariferous plants and the non-polluting natural ecological environment are not fully utilized,the pollination of rapeseed and other insect-based crops is insufficient,and benefits are not brought by beekeeping.[Methods]In response to these problems,Italian bees were first introduced since 2004,and combined with the special natural ecological environment of Tibet,researches on Italian bee biology,queen rearing technology,overwintering technology,and breeding management technology were carried out in high altitude areas.[Results]Through many years of effort,it has filled the gap in bee breeding technology at an altitude of about 4000 m.[Conclusions]It is expected to provide a new pillar industry for Tibetan farmers and herdsmen to increase production and income.

Plants used in traditional beekeeping in Burkina Faso

Beekeeping is one of the recommended approaches in the implementation of poverty alleviation programs in rural areas of Burkina Faso. However, plants that are important in beekeeping have not been identified. The use of parts and organs of plants by beekeepers and their methods of harvesting remain unknown. These limit the conservation efforts of these important plants and affect beekeeping development. The study was carried out in the south-central, eastcentral regions and in Comoé and Boucle of Mouhoun regions ofBurkina Faso. The objective of the study was to identify the plants species used by traditional beekeepers, the different uses made of these plant parts and organs and then to discuss the impact of these activities on the survival of the plant resources. An ethnoapiculture survey was conducted in the main apiculture zone of Burkina Faso, using semi-structured interviews. The methodology of botanical coherence or convergence was applied to classify botanical species. Results showed that 35 botanical species were used in traditional beekeeping. The use of plant parts or organs in traditional hives construction represents 55%, attraction of wild swarms in new beehives is 37.50% and use as a torch or as a smoker, 7.50%. The barks are the organs most used. Trees are botanical type most used. The results are not exhaustive and therefore other additional studies need to be carried out. In order to sustain the use of these important plants, their growing in nursery and their planting in the field are recommended.

Regulation of Pollen Foraging Activity in Apis mellifera Africanized Honeybees Colonies

Efficient honey production requires knowledge about the behavior of the workers and the parameters that influence the strength of the colony. In this study, the objective was to analyze the interaction between the foraging behavior of worker honeybees and pollen storage levels in Africanized honeybees colonies. Colonies with low pollen storage increased pollen intake rates, but this value was 15% lower than colonies with high pollen storage, demonstrating a direct relationship between the pollen storage levels and foraging activity. The difference in pollen intake rates varied according to the number of foraging honeybees and pollen load collected by each individual. Under both high and low pollen storage, colonies returned pollen storage to initial level within 16 days, suggesting that honeybees regulate pollen storage levels around a homeostatic set point. Relationship between pollen storage levels and colony brood production was also found, indicating how alterations in the behavior of each individual can affect the strength of the colony.

Assumptions of Economic Model for Sustainable Productions of Beekeeping in the Bosnia and Hercegovina

Production of bee products using standards of Modern technology requires high specialization and high productivity of labor adequate facilities and equipment, and coordination of natural bee potential with production characteristics of the wider region. Effectively beekeeping today means using several pastures per year with a yield of 50-60 kg per hive. Mobile beekeeping is the only way to achieve high yields of production and it has considerable advantage over stationary one which is less rentable. Mobile beekeeping require higher investments and labor but with good climate and ecological conditions, one can achieve several times higher income than in stationary beekeeping. Some of the success in mobile beekeeping depends of the selection of hives. The hives must be designed to give the bees the best environment for work and development to be most efficient. Data was collected from 57 beekeepers that live in the district. Data analysis was conducted by using standard statistical and economic processes. Criteria for a recommended for the proposed beekeeping model were incomes and profit per hive. For effective beekeeping and production of bee products, especially honey, beekeeper must have adequate equipment and a good bee hives. Beekeeper must have transportation and additional equipment because their movement depends season on the season and distance to pasture.
