Excerpt from Historical Notes on the Causes of Bee Diseases American fo'ul brood. -american foul brood is a very widely dis tributed disease and better known to bee keepers than European foul brood. It 1s the one which 1s generally referred to by the bee keeper at the present time when he speaks of foul brood. The brood affected with this disease is usually capped before it dies. The color of the dead brood presents in general various shades of brown. The marked ropiness of the decaying remains of the dead larvae is probably the most characteristic and well - known feature of the dis ease. The punctured cappings, the scales formed from dried-down larvae, and the disagreeable odor sometimes present are aids to its diagnosis. This disease is clearly an infectious one. The exciting cause of it is a bacterium known as Bacillus larvae. European foul brood. - European foul brood is the disease which Cheshire and Cheyne (p. 25) described in their studies of foul brood. Howard (p. Of Texas, made a very brief and unsatisfactory study of this disease at one time and named it New York bee dis ease or black brood. We are strongly inclined to believe that Burri (p. 68) was working with this disease for the most part during his study of the condition which he refers to as sour brood. Euro pean foul brood is less widely distributed in this country than is American foul brood. In European foul brood one finds, as a rule, most of the diseased brood as yet uncapped. In general, the brood dead of this disease presents various shades of yellow. Usually there is no ropiness; at times, however, there is. That degree of ropiness, however, which is so characteristic of American foul brood is seldom present in European foul brood. There is frequently a slightly sour odor to the diseased brood. The rapidity with which this disease spreads in a new territory and the marked destructiveness of it are features which most bee keepers have experienced who have been so unfortunate as to have the malady affect their apiary. The dis ease is clearly, therefore, an infectious one. The exciting cause is not known. Claims are made by some that certain species of bacte ria stand in direct etiological relation to the disease, but satisfactory evidence to prove such contentions are wanting.

Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.

This is a practical tool to help beekeepers, veterinarians and beekeeping advisory services to properly identify main honeybee diseases and to take the most appropriate actions in the apiary to control and/or prevent disease outbreaks. This publication follows the TECA publication Main bee diseases: good beekeeping practices (2018) which provided a more general overview of good beekeeping practices for bee diseases. This manual is a unique publication because, through its presentation of practical information, simple visuals, and understandable content, it helps beekeepers to correctly identify main honeybee diseases in a timely manner. More specifically, the manual creatively illustrates actions which facilitate the identification of disease symptoms. It also presents a comprehensive list of good beekeeping practices to adopt in the apiary as well as biosafety measures to reduce the risk of the introduction and the spread of main honeybee diseases. The manual’s overall objective is ultimately to support a more sustainable beekeeping sector.
