It follows from the manual “Main beekeeping diseases: Good beekeeping practices” published in 2018. The Istituto Zooprofilattico Sperimentale del Lazio e della Toscana (IZSLT) “M. Aleandri” developed this document in collaboration with the Research and Extension Unit of the Food and Agriculture Organization of the United Nations (FAO), the International Federation of Beekeepers’ Associations (APIMONDIA), and FAO’s Animal Health Service. Definitions and good beekeeping practices reported in this manual, were adopted from the validation activities undertaken in collaboration with the BPRACTICES project. This manual is part of the Technologies and practices for small agricultural producers (TECA) series of the FAO’s Research and Extension Unit (AGDR). Additional details about the TECA platform can be found here: http://www.fao.org/teca. vii Acknowledgments This practical manual was conceptualized and developed by Giovanni Formato and Marco Pietropaoli, Apiculture, Honeybee Productions and Diseases Laboratory of Istituto Zooprofilat- tico del Lazio e della Toscana (IZSLT) “M. Aleandri”, in collaboration with Charlotte Lietaer, Re- search and Extension Unit of Food and Agriculture Organization of the United Nations (FAO).
