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.

Excerpt from European Foulbrood Healthy larvae (pl. III, D, G) slightly older than those described in Group 1 constitute Group 2. The larva now completely fills the bottom of the cell. The dorsal side pressing against the lateral side walls of the cell causes the Contour of the body to be in general hexagonal. The tracheae are seen less easily than ln younger larvae, while the color, glistening appearance, prominence of segments, and turgidity are' similar to those of the younger larvae described in Group 1.

Excerpt from Fungous Diseases of the Honeybee The study of diseases of bees due to fungi has been much later in its development than the study of those caused by bacteria. Much the greater share of the attention of investigators of bee diseases has been given to the two serious bacterial brood diseases, American foul brood and European foulbrood, caused respectively by B lemme and B. Pluton. In America only two reports are on record of diseases of bees and their brood caused by hyphomycetous fungi. In 1896 Howard of Texas, described a new brood disease which he called pickled brood or white fungus, caused by a species of Aspergillus to which he gave the name Aspergillus Two years later he described (15) the same disease as occurring in both pupae and adult bees and stated his belief that this disease had been mistakenly diagnosed by beekeepers as paralysis. In both reports Howard gives descriptions and illustrations of the disease, which he called pickled brood or white fungus, which are more readily applicable to the disease known as sacbrood than to those caused by fungi. He ascribed this disease to the pathogenic Aspergillus, A. Pollini. The dead larvae are described as at first white and watery, later becoming black and swollen, and finally dry ing down to black scales. In no case was the fungus, which Howard assumes to be the cause of the disease, observed on the larvae, and isolations of the organism were not made. In adult bees the disease is described as causing black, shiny, apparently frozen abdomens. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Beekeeping worldwide has seen remarkable development in the face of the growing demand for products from bees by consumers who demand increasingly innocuous products that do not harm the environment. However, it should be noted that, recently, problems have arisen in beekeeping production that could become restrictive factors for the worldwide development of beekeeping. This book includes, in simple and accessible terms, very relevant topics such as the effect of pesticides, the impact of diseases and their management, production and analysis of pollen present in honey, DNA analysis, and sustainable management, among others. This book is answering an expected need for accurate and international information for the productive sector.

Intraspecific communication involves the activation of chemoreceptors and subsequent activation of different central areas that coordinate the responses of the entire organism—ranging from behavioral modification to modulation of hormones release. Animals emit intraspecific chemical signals, often referred to as pheromones, to advertise their presence to members of the same species and to regulate interactions aimed at establishing and regulating social and reproductive bonds. In the last two decades, scientists have developed a greater understanding of the neural processing of these chemical signals. Neurobiology of Chemical Communication explores the role of the chemical senses in mediating intraspecific communication. Providing an up-to-date outline of the most recent advances in the field, it presents data from laboratory and wild species, ranging from invertebrates to vertebrates, from insects to humans. The book examines the structure, anatomy, electrophysiology, and molecular biology of pheromones. It discusses how chemical signals work on different mammalian and non-mammalian species and includes chapters on insects, Drosophila, honey bees, amphibians, mice, tigers, and cattle. It also explores the controversial topic of human pheromones. An essential reference for students and researchers in the field of pheromones, this is also an ideal resource for those working on behavioral phenotyping of animal models and persons interested in the biology/ecology of wild and domestic species.

Insect Pathology: An Advanced Treatise, Volume 2 reviews the significant progress that has been made in insect pathology, as well as the major research trends in the field. This book is concerned with bacterial, fungus, protozoan, and parasitic diseases, along with the epizootiology of infectious diseases, diagnosis, methodology, and microbial control. Organized into 17 chapters, this volume begins with a brief consideration of the taxonomy of entomogenous bacteria, including common problems of bacterial taxonomy as a whole. The book then discusses diseases caused by certain spore-forming bacteria, such as clostridial pathogens and pathogens of the genus Bacillus. The text also explains milky diseases and their development within the insect host; nonsporulating bacterial pathogens that cause diseases in insects; and infections caused by Coelomomyces and Entomophthorales. The book also introduces the reader to insect diseases caused by hyphomycetous Fungi Imperfecti (Deuteromycetes) not usually associated in nature with a perfect stage, diseases associated with Cordyceps, and infections attributed to parasites belonging to the group Sporozoa. This book is essential reading for entomologists.

Bees provide a critical link in the maintenance of ecosystems, pollination. They play a major role in maintaining biodiversity, ensuring the survival of many plants, enhancing forest regeneration, providing sustainability and adaptation to climate change and improving the quality and quantity of agricultural production systems. In fact, close to 75 percent of the world’s crops that produce fruits and seeds for human consumption depend, at least in part, on pollinators for sustained production, yield and quality. Beekeeping, also called apiculture, refers to all activities concerned with the practical management of social bee species. These guidelines aim to provide useful information and suggestions for a sustainable management of bees around the world, which can then be applied to project development and implementation.
