Book excerpt: From the Arctic to South Africa - one finds them everywhere: Ants. Making up nearly 15% of the entire terrestrial animal biomass, ants are impressive not only in quantitative terms, they also fascinate by their highly organized and complex social system. Their caste system, the division of labor, the origin of altruistic behavior and the complex forms of chemical communication makes them the most interesting group of social organisms and the main subject for sociobiologists. Not least is their ecological importance: Ants are the premier soil turners, channelers of energy and dominatrices of the insect fauna.

Download or read book Aphids as Crop Pests 2nd Edition written by Helmut F van Emden and published by CABI. This book was released on 2017-08-23 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aphids are among the major global pest groups, causing serious economic damage to many food and commodity crops in most parts of the world. This revision and update of the well-received first edition published ten years ago reflects the expansion of research in genomics, endosymbionts and semiochemicals, as well as the shift from control of aphids with insecticides to a more integrated approach imposed by increasing resistance in the aphids and government restrictions on pesticides. The book remains a comprehensive and up-to-date reference work on the biology of aphids, the various methods of controlling them and the progress of integrated pest management as illustrated by ten case histories.

Available in PDF, EPUB and Kindle. Book excerpt: Insects are a fascinatingly diverse and beautiful group of animals. They are found on all continents, in caves, underground, inside other insects, in rivers, lakes, puddles, and in our houses. To date, over a million insect species have been named. In this Very Short Introduction, Simon Leather explores insects' evolution, behaviour, and development, highlighting their pivotal role in supporting ecosystems across the planet. He considers the threats of environmental change, including climate change, to insects globally and the potentially catastrophic impact of insect population declines.

Download or read book Sucking Pests of Crops written by Omkar and published by Springer Nature. This book was released on 2020-10-12 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sucking pests are most notorious group of pests for agricultural crops. Unlike most pests with chewing mouth parts, sucking pests cause more severe damage to the crops and are complex to get identified until advanced stages of infection. Not only is this late detection detrimental to their effective control, sucking pests also often cause fungal growth and virus transmission. The book emphasizes on sucking pests of most major crops of India. It aims to reflect Indian scenario before the international readership. This book complies comprehensive information on sucking pests of crops and brings the attention of the readers to this multiple damage causing insect complex. The chapters are contributed by highly experienced Indigenous experts from Universities & ICAR institutes, and book collates useful content for students and young researchers in plant pathology, entomology and agriculture.

This book was released on 2012-12-06 with total page 759 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exactly 35 years after the first Colloquium was held, the Eleventh International Plant Nutrition Colloquium took place from 30 July to 4 August 1989 in Wageningen, The Netherlands. Although impressive progress has been made during the past decades in our understanding of the mechanisms of uptake, distribution and assimilation of nutrients in relation to crop yield and quality, there are still significant gaps in our insight into many fundamental aspects of plant mineral nutrition and related metabolic processes. In spite of improved knowledge of nutrient requirements of crops and improved fertilizer application strategies, the world population remains to be burdened with an enormous shortage of plant products for food, timber, fuel, shelter, and other purposes. The main challenge facing the plant nutrition research community is to at least alleviate the increasing world-wide need for applying scientific knowledge to practical problems in agriculture, horticulture, and forestry. It is therefore felt by many scientists that the Plant Nutrition Colloquia, which are intended to bring together scientists and to integrate knowledge and approaches acquired in plant physiology, biochemis try, soil science, agronomy and related disciplines, have indeed made a significant contribution to the advancement of our knowledge and understanding in this vital and interdisciplinary field of agrobiology. About 260 scientists from 40 nations attended the Colloquium in Wageningen.
