Until recently, it was thought to be exclusively a disease of adult bees, but recent findings indicate that it can also infect larvae. Thus, little is known about the effects of larval Nosema infection. Vitellogenin (Vg) is a key protein necessary for egg-laying, production of brood food, proper immune function, and promotion of longevity through the reduction of oxidative stress. In worker bees, Vg increases in bees of nursing age, at approximately 7 days of age. We therefore investigated the effects of larval Nosema infection on hemolymph Vg and total protein concentration. Larvae infected by a high dose of Nosema ceranae spores developed into adults with 2 fold higher Vg titers. However, they also had 1.3 fold lower total hemolymph protein titers. Thus, Nosema infection resulted in a corresponding 1.7 fold increase in percentage Vg compared to control. Infected bees also had 1.1 fold fewer barbs than did control bees and, we found an inverse relationship between Vg and the number of barbs per lancet. Overall, adult infected bees were not significantly different from controls. Our results indicate that larval N. ceranae infection has a greater impact than does adult infection on adult honey bees. Overall, Nosema ceranae accelerates aging and causes infected bees to resemble older workers or queens.

This book was released on 2014 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nosema ceranae (Microsporidia) is an important honey bee pathogen that is thought to only affect adult bees and which currently has a single effective treatment, the antibiotic fumagillin. However, this treatment may be losing its efficacy. Previously, we showed that N. ceranae can infect Apis mellifera larvae. These data suggested that a sufficiently high dose triggers a larval immune response that conveys some protection. We therefore tested if feeding larvae dead N. ceranae spores can protect bees subsequently exposed to Nosema as adults. In addition, probiotics fed to larvae can activate larval immune genes. However, it was not known if probiotics could actually help bees resist infection. We therefore tested the prophylactic effect of two larval feeding treatments: autoclaved Nosema spores and probiotics. Probiotics were not beneficial: they significantly reduced larval and adult longevity and did not help bees subsequently resist adult infection (measured as the number of midgut Nosema spores). However, Nosema treatment reduced adult infection levels by 57% without significantly altering larval or adult longevity as compared to controls. Nosema treatment also had no significant effect on adult morphology, though it slightly increased bee mass at adult emergence. These data provide the first evidence that honey bee disease resistance can be boosted by larval exposure to a dead pathogen, a promising approach that deserves further study.

Book excerpt: Honey bee pathogens are spread worldwide and are strongly related to the decline of honey bee populations, which has severe implications for beekeeping, honey production and ecology. Honey bee pathogens are continuously studied by researchers with the aim to better understand the host-parasite relationship of these pathogens and the effects that they have on bee colonies. Honey bee pathogens include bacteria (i.e., Melissococcus plutonius and Paenibacillus larvae), microsporidia (i.e., Nosema apis and Nosema ceranae), fungi (i.e., Ascosphaera apis), protozoa (i.e., Lotmaria passim, Crithidia bombi and Crithidia mellificae) and viruses (i.e., ABPV, CBPV, IAPV, KBV, DWV, BQCV and SBV). All of these pathogens are able to infect other bee species; infections would have important implications for their life cycles (e.g., Osmia sp. and Bombus sp.) or cause unknown epidemiological effects for other hymenopterans. In addition, old and new invasive pests (such as Varroa destructor, Aethina tumida, Vespa velutina, etc.) necessitate more studies to define their role as possible vectors or possible sources of infection for honey bees. For these reasons, knowledge on honey bee pathogens has become a matter of public interest and is connected with the critical role of honey bee health. The aim of this Special Issue is to explore honey bee pathogens, considering any aspect in relation to host-pathogen interaction and highlighting the possible interaction and spillover with other bee species and invasive pests, through a series of research articles that focus on different aspects of pathologies.

Available in PDF, EPUB and Kindle. Book excerpt: The familiar European hive bee, Apis mellifera, has long dominated honey bee research. But in the last 15 years, teams in China, Japan, Malaysia, and Thailand began to shift focus to the indigenous Asian honey bees. Benjamin Oldroyd, well known for his work on the genetics and evolution of worker sterility, has teamed with Siriwat Wongsiri, a pioneer of the study of bees in Thailand, to provide a comparative work synthesizing the rapidly expanding Asian honey bee literature. After introducing the species, the authors review evolution and speciation, division of labor, communication, and nest defense. They underscore the pressures colonies face from pathogens, parasites, and predators--including man--and detail the long and amazing history of the honey hunt. This book provides a cornerstone for future investigations on these species, insights into the evolution across species, and a direction for conservation efforts to protect these keystone species of Asia's tropical forests.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Insect Pathology is designed for a broad spectrum of readers. Is should be useful to students, lecturers, and researchers requiring information about the principles in insect pathology and the biology of pathogens. It should serve as a resource for specialists to learn about other insect pathogen systems, for generalists to become aware of advances in insect pathology, and for scientists and students, beginning or otherwise, interested in learning about insect pathology. This book was originally intended to update the 1949 test by E. A. Steinhaus entitled Principles of Insect Pathology. The purpose for this book was twofold: To serve (1) as a text for an insect pathology and/or biological control class and (2) as a comprehensive reference source. Because this book summarizes much of the available information, its usefulness as a textbook for an insect pathology class is apparent. Although the literature citations are extensive, they are far from complete. The literature in insect pathology is voluminous and for the past decade has been expanding at an almost exponential rate. A complete review of the literature is beyond the scope of the book, and an omission of a reference does not preclude its importance. Our citations, however, should serve as a good starting point for those who wish to obtain further information. We have attempted to cover equally all subdisciplines, but shortcomings are unavoidable. For these, we take full responsibility.
