Hardcover. Zustand: New. Contents: 1. Why We Need Biopesticides: Some Case Studies of Chemical Pesticides. 2. Insecticide Resistance and Case Histories. 3. History and Development of Biological Control. 4. Biopesticides Classification and Their Formulations in India. 5. Nano-Biopesticides for Management of Insect Pests of Crops. 6. Impact of Biopesticides Application on Crop Quality and Environmental Quality. 7. Indian Biopesticide: Market, Consumption, Growth and Opportunities. 8. Biopesticides: Research and Development Activities. 9. Biopesticide Commercialization: World-wide Regulation Policies for Registration and Use of Biopesticides. 10. Promotion of Biopesticides in India: Role of Government and Growers. 11. Growth of Biopesticides: Driving Force and Set-Back. According to estimates, plant pests and diseases cause at least 10% of the world's food production to be lost. Additional pest and disease losses occur after harvest, where it is estimated that up to 13% of the total calories generated are lost after leaving the farm gate, in addition to in-field losses. According to Indian viewpoints, biotic stressors cause a 2026% annual loss of food commodities. The effects of the "Green Revolution" (GV) multiplied crop production and productivity, which ultimately affected the livelihoods of Indian civilians. However, the introduction of numerous inorganic plant protection inputs resulted in irreversible harm to the environment, human lives, and material wealth. The focus on environmentally friendly plant protection measures, particularly microbial biopesticides, has expanded as a result of current conditions and Indian government regulations on chemical pesticides that take into account their negative effects. In the recent past, India's biopesticide industries, demand, consumption, market, etc., have grown tremendously. It is expected that between 2040 and 2050, the biopesticide industry would either match or surpass those of chemical pesticides. Global population growth is projected to reach 9 billion people by 2050, and the duty to increase food production by 70% of current levels in order to feed this population has led to a ruthless shift toward the use of artificial agricultural inputs. Nevertheless, there are ways to enhance food production to the anticipated level by using Integrated Pest Management, which enables the prudent application of inorganic inputs in conjunction with environmentally benign tactics like microbial biopesticides.

Hardcover. Zustand: New. Zustand des Schutzumschlags: New. 1st Edition. Contents: 1. Schwartz theory of distribution. 2. Operational calculus. 3. Generalized Schwartz distributions : the Boehmians. 4. Wavelet transforms fractional calculus and references integral transforms. 5. Distribution, Boehmians and integral transforms. 6. Hartely transform for Boehmians. 7. Wavelet transform and Boehmians. 8. Selected applications. References. Prior this composition in the form of the text, on Boehmians and Boehmians spaces, till to date the literature has no record of a book or a monograph. This attempt is to explain the concept of the theory of Boehmians, which is the generalization of the Schwartz theory of distribution. The text of the present book contains the basic mathematics about the theory and various researches conducted during the past. Mathematics involved, is made as simple as possible, in order to reach to every young researchers and the matured mathematicians. If not all, but maximum researches in this field have been included. The prerequisites to study this subject are real analysis, complex analysis and the functional analysis.

Table I Dipteran flower visitors and their visited plant species in and around Kolkata. Table II Plant species and dipteran their flower visitors in and around Kolkata. From the preface Handbook on Flower visiting Diptera is the emphasis on the association between the flies and the flowers of the trees shrubs herbs gardens and medicinal plants. The very reason of structuring this handbook is that the beginner will be able to relate the flowers and the insects together as an integral part of a given ecosystem and biodiversity strategies. The diptera are probably the second most common order of flower visitors and pollinators worldwide and may rival even the hymenopterans in their diversity especially in tropical countries. Today flies are being considered seriously as alternative pollinating agents of several cash crops and play a major role in maintenance of ecosystem diversity and ensuring food security. 54 pp.
