Book Description
The yields of agricultural crops can be significantly increased through good management practices including effective pollination. Cucurbits mainly depend on insects for pollination because the male and female organs do not occur in the same flower and pollen grains are large and sticky to be carried by wind. Chow-chow is commonly called as chayote (Sechium edule (Jacq) Sw.) belongs to family Cucurbitaceae. The efficacy of different species of honey bees viz., Apis cerana, A. mellifera, A. florea and T. iridipennis in cross-pollination of chow-chow was studied during summer 2001 at Regional Research Station, University of Agricultural Sciences, GKVK, Bangalore. Activity of different insect pollinators including honey bee species and their influence on fruit set, fruit quality and seed quality parameters were studied. The quantity and quality of nectar from pistillate and staminate flowers was also estimated to know its impact on foraging activity. At flowering, chow-chow crop was frequently visited by 26 insect species of which 14 belonged to the order; Hymenoptera and four each belong to order Diptera, Lepidoptera and Coleoptera. Apis dorsata, A. cerana indica, A. florea and Trigona iridipennis which accounted more than 82 per cent of the total insect pollinators visiting chow-chow crop. Significantly maximum fruit set was found in open pollinated plots (81%) and the lowest was found in control plots (10.5%). Among the honey bee species, maximum fruit set was found in A. florea caged plots (78%) and the lowest was found in T. iridipennis caged plots (61%).

Book Description
This edited book highlights the latest information on the use of nanotechnology, satellite technology, and biotechnological tools in pest management. It covers the role of climate change and ecology in managing pests and also their molecular identification. Other methods that the book encompasses are organic pest management, host-plant resistance, semiochemicals, and bio-control technology. The book also covers insect pollinators which play important role for fruits in horticultural crop production. Intensive and extensive cultivation of horticultural crops lead to serious pest problem. Climatic conditions in India and elsewhere due to which new pests have emerged that causes severe damage to the horticultural crops. In response to this, researchers have developed new techniques to fight pests and their growing resistance to pesticides. This book covers the latest information on identity, biology, damage, seasonal development, and pest management of the horticultural crop pests. It serves to be an essential tool for horticultural professionals, including development officers, horticulturists, field-level extension workers, nurserymen, planters, and entomologists, and is a valuable source of reference for relevant researchers, teachers, and students in the region.

Book Description
This fascinating book examines the biology and culture of foods and beverages that are consumed in communal settings, with special attention to their health implications. Nina Etkin covers a wealth of topics, exploring human evolutionary history, the Slow Food movement, ritual and ceremonial foods, caffeinated beverages, spices, the street foods of Hawaii and northern Nigeria, and even bottled water. Her work is framed by a biocultural perspective that considers both the physiological implications of consumption and the cultural construction and circulation of foods.

Book Description
The golden era of food microbiology has begun. All three areas of food microbiology—beneficial, spoilage, and pathogenic microbiology—are expanding and progressing at an incredible pace. What was once a simple process of counting colonies has become a sophisticated process of sequencing complete genomes of starter cultures and use of biosensors to detect foodborne pathogens. Capturing these developments, Fundamental Food Microbiology, Fifth Edition broadens coverage of foodborne diseases to include new and emerging pathogens as well as descriptions of the mechanism of pathogenesis. Written by experts with approximately fifty years of combined experience, the book provides an in-depth understanding of how to reduce microbial food spoilage, improve intervention technologies, and develop effective control methods for different types of foods. See What’s New in the Fifth Edition: New chapter on microbial attachment and biofilm formation Bacterial quorum sensing during bacterial growth in food Novel application of bacteriophage in pathogen control and detection Substantial update on intestinal beneficial microbiota and probiotics to control pathogens, chronic diseases, and obesity Nanotechnology in food preservation Description of new pathogens such as Cronobacter sakazaki, E. coli O104:H4, Clostridium difficile, and Nipah Virus Comprehensive list of seafood-related toxins Updates on several new anti-microbial compounds such as polylysine, lactoferrin, lactoperoxidase, ovotransferrin, defensins, herbs, and spices Updates on modern processing technologies such as infrared heating and plasma technology Maintaining the high standard set by the previous bestselling editions, based feedback from students and professors, the new edition includes many more easy-to-follow figures and illustrations. The chapters are presented in a logical sequence that connects the information and allow students to easily understand and retain the concepts presented. These features and more make this a comprehensive introductory text for undergraduates as well as a valuable reference for graduate level and working professionals in food microbiology or food safety.
