Book excerpt: Honey bees (Apis melliferaL.) are the most agriculturally beneficial eusocial insects for crop pollination. Chemical communication is critical in maintaining colony structure and activity, which may be exploited by parasites. Varroa destructor (Anderson and Trueman; Acari: Varroidae) is regarded as one of the biggest threats to apiculture, blamed for annual colony mortalities of over 30% in some regions. The objectives of this thesis were to identify odorants important to V. destructor for further development of techniques to disrupt its lifecycles through in-colony treatment. Honey bee colony volatile collections involving ex-situ techniques were used to identify individual compounds and odor detection sensitivity of V. destructorto these compounds through gaschromatography-mass spectrometry and gas chromatography-linked electrotarsal detection, respectively. Volatile components identified in this and previous research were then tested for concentration-dependent responses using electrophysiology. Electrotarsogram responsesindicated significant difference among odorants in eliciting responses, suggesting the potential application of this procedure in screening putative repellents or odors that disrupt host detection (disruptants) to live V. destructor. Results from this research can be applied o colony-wide testing of active odorants in developing effective alternative methods for V. destructor control as well as developing methods for future research exploring chemical ecology of social insects.

Download or read book Status of Pollinators in North America written by National Research Council and published by National Academies Press. This book was released on 2007-05-13 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 book was released on 2012-04 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Apiculture forms an essential and vital component of sustainable integrated rural development programme as it improves the economy of farmers by enhancing the productivity of agricultural crops and honey production. Despite its great potential, beekeeping industry is facing several constraints, which needs immediate attention. Among these, Varroa destructor Anderson and Trueman, an ectoparasitic mite of brood and adult bees, is a serious pest of Apis mellifera L.). In the last three years, beekeeping in India is adversely affected by this mite. In the present scenario, 90 per cent apiaries and 50 per cent colonies are affected by this mite. Varroa was first described on its native host, the Asian honey bee (Apis cerana Fab.) in 1904 in Java (Oudemans, 1904). Some of behavioural traits which were acquired by honey bees against Varroa are tendency to swarm and willingness to abandon their hives may have effectively countered the mite, but these traits also suggested difficulty in domestication of this species.Genus Varroa consists of at least four but possibly seven distinct species. Among the four recognized species, the most destructive and largest among these is Varroa destructor.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Honey bees suffer from parasitism from Varroa destructor, which spreads between colonies via several transmission routes. Mites infest the brood cells of developing bees, feeding on and transmitting pathogens to their hosts. When mites are inside capped brood cells, they are protected from beekeeper applied acaricides. In this study, I used indoor storage to halt brood production, with the goal of reducing the protective brood cells and force mites into a phoretic state to increase susceptibility to treatment. I tested the efficacy of a novel strain of an entomopathogenic Metarhizium fungus as a mite control method against oxalic acid (OA). I observed that indoor storage effectively reduced the quantity of capped brood. However, I did not observe a proportional associated increase in phoretic mite population. Metarhizium reduced Varroa populations at similar rates when compared with OA, but neither OA nor Metarhizium performed significantly better after indoor storage compared to outdoor storage. This research shows promise for novel tools to reduce mite infestations and combat pesticide resistance when treating V. destructor.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Honey bees, Apis mellifera L., are beneficial insects for human nutrition and agriculture. They are important crop pollinators; contributing $15-20 billion to the agricultural economy in the United States. Many factors can lead to a decline in these utilitarian insects, and Varroa destructor, an ectoparasitic mite (Anderson & Trueman) is one of the most important worldwide. This pest, feeds on fat body tissue of honey bees, and cause collapse of untreated colonies within two years. Although beekeepers have used acaricides to control these mites, they continue to face resistance problem to the chemicals. Emerging acaricide resistance in varroa mites have compelled beekeepers to explore alternative ways to control varroa mites. The effectiveness of three non-acaricidal approaches to control varroa mites were tested under laboratory conditions. Varroa mites used for testing collected from the research beehives in Moscow, Idaho, USA. We tested application of spores of Metarhizium brunneum at concentrations of 5.7 x 10^4, 2.24 x 10^5, 5.05 x 10^5, 9.2 x 10^5, and 2.05 x 10^6 viable conidia in per ml−1, compared with oxalic acid and thymol. Materials were sprayed with a Potter Precision Spray Tower machine (Burkard Scientific, UK) and evaluated for their effectiveness on varroa mite mortality. The same number of varroa mites for each objective was used and recorded daily mite mortalities. 3.0% solution of oxalic acid and thymol killed varroa mites quickly than entomopathogenic fungi in 48h. No significant differences were observed in the virulence of mites between fungal concentrations. For the second experiment, 1.5% solution of oxalic acid and 10^4, 10^5, 10^6, 10^7 and 10^8 concentrations of Metarhizium brunneum were applied by mixing (500 μl oxalic acid and 500 μl M. brunneum). The optimal effect on varroa mite mortality was observed for the mixture solution oxalic acid with 10^8, 10^7 and 10^6 concentrations of M. brunneum. There was a noticeable difference between the mixture solutions with 10^8, 10^7 and 10^6 concentration of M. brunneum and 1.5% solution of pure oxalic acid application in 24h. The effectiveness of 105 and 104 mixture solutions were lower than other solutions.

Download or read book Bees written by Richard M. Florio and published by Nova Science Publishers. This book was released on 2012-01-01 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: For students of animal behavior, honey bees are an intriguing organism, interacting in a complex eusocial colony setting as well as with the environment as they forage over wide areas. Much of that behavior is moderated by odors, which honey bees can detect at extremely low concentrations. This book presents current research from across the globe in the study of bees, including the importance of odor in learning and behavior of the honeybee; the role of honeybees in pollination ecology; threats to the stingless bee in the Brazilian Amazon; honeybee viruses and age-related associative and non-associative learning performance in honeybees.

Download or read book Pollinators and Pollination written by Jeff Ollerton and published by Pelagic Publishing Ltd. This book was released on 2021-01-18 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unique and personal insight into the ecology and evolution of pollinators, their relationships with flowers, and their conservation in a rapidly changing world. The pollination of flowers by insects, birds and other animals is a fundamentally important ecological function that supports both the natural world and human society. Without pollinators to facilitate the sexual reproduction of plants, the world would be a biologically poorer place in which to live, there would be an impact on food security, and human health would suffer. Written by one of the world’s leading pollination ecologists, this book provides an introduction to what pollinators are, how their interactions with flowers have evolved, and the fundamental ecology of these relationships. It explores the pollination of wild and agricultural plants in a variety of habitats and contexts, including urban, rural and agricultural environments. The author also provides practical advice on how individuals and organisations can study, and support, pollinators. As well as covering the natural history of pollinators and flowers, the author discusses their cultural importance, and the ways in which pollinator conservation has been portrayed from a political perspective. The book draws on field work experiences in South America, Africa, Australia, the Canary Islands and the UK. For over 30 years the author has spent his career researching how plants and pollinators evolve relationships, how these interactions function ecologically, their importance for society, and how we can conserve them in a rapidly changing world. This book offers a unique and personal insight into the science of pollinators and pollination, aimed at anyone who is interested in understanding these fascinating and crucial ecological interactions.
