The book Honey Analysis has 15 chapters divided into two sections: one section that is dedicated to the analysis of bioactive, physicochemical, and microbiological compounds and another that addresses techniques for the detection of residues and heavy metals. We have been able to compile a book with chapters by authors from nine countries (Brazil, Chile, Italy, Malta, New Zealand, Poland, Romania, Serbia, and Turkey) and at least three continents (South America, Europe, and Oceania). The topics discussed here are physical-chemical analysis of honey, new methods for amino acid analysis, chemical residues, heavy metals, phenolic content and bioactive components, microbiological analysis, antimicrobial activity, and honey as functional food. Also there are notions of trade and characterization of honey in these countries, presenting the reality of the local market of these countries and their perspectives so that we can know more about the techniques used as well as the importance of this activity for each country. This may facilitate the use of innovative techniques that may enable increased competitiveness and the world honey trade.

Benefits of Entomophile Pollination in Crops of Brassica napus and Aspects of Plant Floral Biology

By Emerson D. Chambó, Simone C. Camargo, Regina C. Garcia, Carlos A.L. Carvalho, Maria Claudia C. Ruvolo-Takasusuki, Ludimilla Ronqui, Claudio Silva Júnior, Pedro R. Santos and Vagner de Alencar Arnaut de Toledo

Rapeseed (Brassica napus L. var. oleifera) is an oleaginous species of the Brassicaceae family, being the third most produced oleaginous in the world. Rapeseed can produce fruits and seeds from both self-pollination and cross-pollination. However, cross-pollination rate is approximately 30% and may suffer variations due to the abundance and diversity of pollinator insects, cultivar and meteorological conditions. Different researchers have reported that pollination by insects, especially Apis mellifera honeybee, on rapeseed flowers provides an increase in productivity, improving yield and contributing to the uniformity and initial pod establishment. It is estimated that the economic value of A. mellifera honeybees for rapeseed cultivation in Brazil is US$ 8.2 million. The objective of this chapter is gathering data for a compilation of information regarding rapeseed culture and the importance of A. mellifera in Brassica napus pollination.

Development of Beekeeping: An Analysis Using the Technique of Principal Components

By Emerson Dechechi Chambó, Regina Conceição Garcia, Fernando Cunha, Carlos Alfredo Lopes de Carvalho, Daiane de Jesus Oliveira, Maiara Janine Machado Caldas, Nardel Luiz Soares da Silva, Ludimilla Ronqui, Claudio da Silva Júnior, Pedro da Rosa Santos and Vagner de Alencar Arnaut de Toledo

Beekeeping is an economic activity of the Brazilian agricultural sector and a powerful tool to achieve sustainable development. However, beekeeping still remains a modest activity compared to other areas, with a lack of technical knowledge and beekeeping practices that need to be standardized. This study represents a proposal for the diagnosis of beekeeping, to facilitate decision-making and to provide a faster development of the beekeeping activity. We investigated the process of adoption of beekeeping practices of 28 beekeepers and the quality of the honey produced by them in the Western region of Paraná, using the technique of Principal Components Analysis after the construction of apicultural indexes. Specifically, the honey produced in the Western region of Paraná be included in the requirements of national and international legislation, but the beekeeping practices adopted still require standardization so that the beekeepers have higher honey production. Also, the transformation of variables into apicultural indexes for later use in the analysis of principal components proved to be efficient to draw a beekeeping profile. Our research proves to be efficient in accurately diagnosing beekeeping bottlenecks, which may enable better decision-making and thus attract new entrepreneurs and increase their relevance to achieve sustainable rural development.
