Chalkbrood is a highly contagious disease of the honeybee Apis mellifera caused by the heterothallic fungus Ascosphaera apis. It was first identified in Queensland in 1993, and, since that time, the disease has spread throughout Australia. Although not usually fatal, the disease causes reduced honey production. The effects of chalkbrood can be controlled by improved management techniques such as strengthening colonies with bees or hatching brood and enlarging colony entrances to aid ventilation. This project has investigated the antifungal efficacy of over 50 natural products and found that a number of essential oils were particularly efficacious at controlling the in vitro growth of Ascosphaera apis. Of these, citral-containing oils were the most active, with growth inhibition at 250 ppm. These findings need to be progressed to field studies to evaluate product efficacy in the hive and to determine whether residues are a problem with this form of disease control. The most active antifungal test agents in this study were Nepalese Lemon Grass oil, Lemon Scented Eucalyptus (Eucalyptus citrodora) oil, Lemon Scented Tea Tree (Leptospermum petersonii) oil and a particular fraction of a New Zealand Manuka (Leptospermum scoparium) oil. All of these agents presented with a Minimal Fungicidal Concentration against Ascosphaera apis of 250 ppm. Citral is the major component of the former three oils while the active chemical in the New Zealand Manuka (Leptospermum) oil is a unique terpenoid agent (leptospermone). Interestingly, a number of other oils which should have contained significant levels of citral (East Indian Lemon Grass oil, cold-pressed Lemon oil, Natural Citral and lemon essential oil) returned negative MFC scores at 1000 ppm or greater. Several other oils exhibited moderate antifungal activity (active at 500 ppm) against Ascosphaera apis (Citricidal, several Tea Tree oils, a number of other New Zealand Leptospermum oils, a ginger oil and a lavender oil). The remaining essential oils were shown to be ineffectual against Ascosphaera apis in this in vitro test system.

This book has a wider approach not strictly focused on crop production compared to other books that are strictly oriented towards bees, but has a generalist approach to pollination biology. It also highlights relationships between introduced and wild pollinators and consequences of such introductions on communities of wild pollinating insects. The chapters on biochemical basis of plant-pollination interaction, pollination energetics, climate change and pollinators and pollinators as bioindicators of ecosystem functioning provide a base for future insights into pollination biology. The role of honeybees and wild bees on crop pollination, value of bee pollination, planned honeybee pollination, non-bee pollinators, safety of pollinators, pollination in cages, pollination for hybrid seed production, the problem of diseases, genetically modified plants and bees, the role of bees in improving food security and livelihoods, capacity building and awareness for pollinators are also discussed.

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.

key pollinators honey bees, have been evolved for million years along with flowering plants. Asia is rich with species diversity and the bees are known to play vital roles in maintaining the the local fauna and sustain the agricultural crops to secure food sources for human consumption in the region, where the population continue to grow. Southeast Asia is regarded as a hot spot for scientists to study ecological interaction and co-evolution between hosts and parasites 9n different species of honey bees. The most serious and widespread bee pathogens and parasites today in the European honey bee are parasitic mites. nosema, kashmir bee virus which may have originated from Asian honey bees in South East Asia, More information on Asian honey bee health can also reflect the future threat in European honey bee worldwide especially when the global warming and fast transportation allow the prevalence and dissemination of tropics pathogens and parasites. This book aims to provide the current bee health status of honey bees in Asia which are now under emerging pressures from natural causes and human activities in modern society of globalization. Symbiotic relationships between living organisms and honey bees are also described
