The present investigation entitled, "Population dynamics and management of cabbage white butterfly, Pieris brassicae (Linn.) in district Sultanpur (U. P)" was carried out at the Farmer field, village Bhain, district Sultanpur, U. P. during the rabi season 2012-13 and 2013-14. In order to see the incidence and management of invasive pest i.e. cabbage white butterfly, which is a regular pest and causing heavy damage in the Himachal Pradesh, some parts of Uttarakhand and U. P., . Incidence of this pest is studied to plan the dates of sowing, in order to escape the pest infestation. Management is done with the chemicals and bio pesticides to minimize the indiscriminate use of insecticides for the pest i.e. cabbage white butterfly (Pieris brassicae). Laboratory study was also carried apart from the field work on biology of cabbage white butterfly and mortality of catterpillars against certain chemical and bio-pesticides. Studies on the incidence of cabbage white butterfly (Pieris brassicae) population with weather parameters given in table 4.1, figure 4.1 and table 4.2, figure 4.2. The occurrence of cabbage white butterfly (Pieris brassicae) was commenced from 4th standard week

This book is an exposition of how political, cultural, historical, and economic structures and processes shape the nature and character of curriculum landscapes globally. By developing theoretical connections and providing contextual background, Kumar explores how colonialism and imperialism, state-led ideological control, and the wave of neoliberalism and capitalism insidiously impact the process of curriculum development in different parts of the world. Kumar also underscores how intellectual movements such as Marxism and postmodernism have shaped curriculum theory in varied political and economic settings. By emphasizing the connections between and among diverse cultural and political conceptualizations of curriculum, this volume contributes to the internationalization of curriculum studies discourses.

Although boron (B) is a micronutrient, it is frequently found at toxic concentrations in soils and ground waters in arid and semi-arid conditions worldwide. Boron poses a challenge as its management is difficult due to its high permeability and presence as an uncharged molecule at physiological pH. B is now recognized as a toxic component of the saline milieu which interacts with salinity and further aggravates its toxic effects. Interactions between salinity and B toxicity are rather complex. The mechanism of boron uptake under saline conditions is not well known. Under saline and excessive B conditions, absorption and translocation of B by passive diffusion might be inhibited by decreased transpiration rates. Inadequate information regarding the response of plants to the combination of excess B and salinity on plant growth and yield is available. So, this study was undertaken to analyze and compare the combined effect of boron and salinity and to evaluate the response of wheat varieties differing in their tolerance to boron and salinity stresses.

This book deals with all major aspects including establishment of a new fish farm, its management, good practices, and ideal conditions for optimum production of fish. Important infectious and non-infectious diseases of fish have been amply elaborated along with methods of their diagnosis, prevention and control. Great emphasis has been given to the hygienic aspects in fish production and quality assurance of fish as food. The diseases transmissible to consumers through unhygienic fish and fish products are also highlighted. Lucid illustrations make the book a reading pleasure. The authors earnestly believe that this book will prove to be a unique resource for the students, educators and the professionals.

This book provides a general introduction as well as a selected survey of key advances in the fascinating field of plant cell and tissue culture as a tool in biotechnology. After a detailed description of the various basic techniques employed in leading laboratories worldwide, follows an extended account of important applications in, for example, plant propagation, secondary metabolite production and gene technology. Additionally, some chapters are devoted to historical developments in this domain, metabolic aspects, nutrition, growth regulators, differentiation and the development of culture systems. The book will prove useful to both newcomers and specialists, and even “old hands” in tissue culture should find some challenging ideas to think about.
