Light Trap

The book covers information on some theoretical aspects related to working of light trap like organs of insect vision and orientation towards light source, electromagnetic radiation, spectrum visible/attractive to insects, characteristics of electric lamps used, factors affecting trap catches and identification of migratory phases based on analysis of light trap catches etc. Practical aspects include principles and practice of light trap operation, trap designs and light sources to be used and study of seasonal activity and direct control of pest population using light traps. Last chapter covers extensive reviews of field trials and experimental work conducted on survey and control of some economic species of crop pests. The manuscript is supplemented in the end with a list of references cited in the text along with selected references on light trap studies for consultation to all the concerned. The main objective of this book is to revive interest among the scientists, research scholars and students in using this novel technique of pest control and make it more popular among the farmers through research and extension work. We hope this book would serve as a reference/text book, meeting the essential requirements for advanced course 'Light trap as IPM tool'.

Insect trapping is a basic field research tool for many biologists, whether they are studying insect pests, disease vectors or insect ecology for its own sake. Any field entomologist contemplating a new insect trapping program or looking to improve or develop an existing scheme will benefit from this broad review of flying insect traps, in which the author draws on a wide variety of methods used by different research projects from all over the world. Over the years a great many traps have been developed and endlessly modified to suit particular species, habitats, and research requirements. In virtually every case the design of the trap interacts with the specific behavior of the insects involved to bias trap efficiency. In addition, the limited dialogue between workers in different subject disciplines and habitats has caused a shortage of new information available to field entomologists as a whole. Describes and evaluates the main methods of trapping flying insects Brings together results from agricultural/forest/pest studies and those from medical entomology

As the judges of the Whitbread Prize noted, 'Burnside's poems have the rare power to alter one's perception of the world and of language...a sensory delight with an epiphany on every page.' Once again, in this, his eighth collection of poetry, John Burnside is looking deeply into the ways we see our world: addressing the organic relationship between the environment and the unconscious, between ideas and the creatures, in poems whose protagonists - from the deer who pass through a suburban garden to the poet's six-month-old son - are infinitely mysterious, difficult and 'out there'. These are poems that move beyond the traditional idea of 'nature poetry', investigating the very basis of our knowledge, not only of living things, but of the play of gravity and light that makes our world and theirs possible. Resonant and luminous, this is work of intimacy and wonder from one of Britain's most important poets.

Due to the worldwide importance of rice as a crop plant, the biology of rice pests is of great interest to agricultural research. This timely book brings together contributions from the fields of entomology, agronomy, population ecology, and biostatistics to provide a comprehensive survey of rice-insect interaction. Among the topics discussed are - crop loss assessment - economic thresholds and injury levels for incest pests - mosquito leafhoppers and planthoppers population dynamics - pheromone utilization - techniques for predator evaluation - chemical based for insect resistance - applications of tissue culture - systems analysis and - rice pestmanagement. With its emphasis on experimental techniques of pest analysis and control, Rice Insects: Management Strategies will be a valuable reference for researchers and practitioners alike.
