This book, state of art situation in patterns of behaviour is presented by the authors, each with expertise in respective fields on diverse aspects such as pollination, predation and parasitism, forest and agricultural pests, besides the dynamics of aquatic insects in general and dragonflies in particular, in addition to insect vectors of diseases. The need for an appreciation of the differentiation processes controlling growth and development of plant galls has ...
Entomology is the study of insects. This book is about the need to find solutions to the problems that insects cause to plants and crops. In recent years, biochemistry, genetics and molecular biology have become essential to the understanding of these problems. Using the molecular biology approach, one can now transfer and evaluate genetic characteristics from many insects. This book emphasizes the need for and relevance of studying the molecular aspects of ...
Rapid depletion and degradation of species in diverse ecosystems and the implications of this for human welfare have led to for increasing concern. Biodiversity or variability among living organisms and the ecological complexes of which they are a part, is essential for ensuring the basic ecological services and resources necessary for sustaining human welfare. The loss of biodiversity is therefore, considered one of the most serious problems threatening the ...
The present volume aims at identifying the biochemical parameters in thrips-host plant interactions. With increased inputs in our understanding of chemical ecology, this volume paves the way for an integrated approach to the study of thrips-host plant interactions, including host preferences and trophic diversity in terms of infestation mechanics and host plant tissue responses to thrips feeding injury. Emphasis has been laid on the elucidation of the action of ...
This work aims at a synthesis of available knowledge of litter ecosystem in tropical forests, from the viewpoint of the sustainability of entomological resources at various levels, laying stress on their biological diversity with emphasis on their functional diversity. At a time when we are losing natural forests at a fast rate through conversion of forest into cultivated land, the thoughts of dwindling biodiversity through lack of litter become predominant. Of ...
Functional dynamics of insects relate to diverse aspects of host plant selection behaviour emphasizing the role of sensory physiology, biochemical attributes and energetics in the regulation of feeding and reproduction. The ability of phytophagous insects to perceive numerous chemical compounds in plants through a highly developed chemosensory system appreciably influences the choice of the food plant. Versatility is an essential prerequisite in insects to ...
India being one of the top twelve mega biodiversity countries in the world, the increasing rate of erosion of biodiversity has been causing great concern. Because of socio-economic rate of erosion of biodiversity has to come to occupying the central stage as it holds the ‘Key to changes, biological diversity has to come to occupying the central stage as it holds the ‘Key to the maintenance of the world’. Biodiversity is a multifaceted science bringing the ...
One of the principal aims in writing this book pertains to the increasing impact of human influence on natural habitats in recent years, more notably to the loss of habitats in recent years, more notably to the loss of habitat quality. Increased urbanization, considerable reduction in natural forest areas, changing ecology of fresh water ecosystems, lakes and wet lands, besides changing microhabitats, have had their impact on insect populations. A ...
