Book Description
The crab spider is an ideal species on which to test basic questions of lifetime fitness, but ecologists had previously lacked experimental data needed to comprehensively test individuals making foraging decisions. This book recounts Morse's influential experimental discoveries, moving from individuals to communities to ecosystems.

Book Description
The history of biological control of harmful organisms by mites is marked by outstanding achievements with a few premiere natural enemies. Early works concentrated on the use of predatory mites for the control of synanthropic flies, More recently, the focus has been mostly on mites of the family Phytoseiidae for the control of plant feeding mites. This is an important family of acarine predators of plant pest mites, which are effectively used in agriculture worldwide. Besides the vast knowledge in several species in this family, there are as well many opportunities for biological control, represented in an array of organisms and through the improvement of management techniques, which are constantly explored by researchers worldwide. This has resulted in an increasing interest in predatory mite species within the families Stigmaeidae, Ascidae, Laelapidae, Rhodacaroidea, Macrochelidae, Erythraeidae and Cheyletidae, among others. This book will compile important developments with predatory mite species within these families, which are emerging as important tools for integrated pest management. New developments with predatory insects and pathogenic organisms attacking mites will also be a subject of this book. Finally, the potential and gaps in knowledge in biological control of acarine plant pests will be addressed.

Book Description
The International Centre for Advanced Mediterranean Agronomic Studies (CIHEAM), established in 1962, is an intergovernmental organization of 13 countries: Albania, Algeria, Egypt, France, Greece, Italy, Lebanon, Malta, Morocco, Portugal, Spain, Tunisia and Turkey. Four institutes (Bari, Italy; Chania, Greece; Montpellier, France; and Zaragoza, Spain) provide postgraduate education at the Master of Science level. CIHEAM promotes research networks on Mediterranean agricultural priorities, supports the organization of specialized education in member countries, holds seminars and workshops bringing together technologists and scientists involved in Mediterranean agriculture and regularly produces diverse publications including the series Options Méditerranéennes. Through these activities, CIHEAM promotes North/South dialogue and international co-operation for agricultural development in the Mediterranean region. Over the past decade, the Mediterranean Agronomic Institute of Zaragoza has developed a number of training and research-supporting activities in the field of agroecology and sustainability of agricultural production systems. Some of these activities have been concerned with the rational use of pesticides and more particularly with the implementation of integrated control systems in order to gain in efficacy and decrease both the environmental impact and the negative repercussions for the commercialization of agricultural products.

Book Description
Pests cause damage to the economic value of crops and stored products, while vectors are responsible for the transmission of disease-causing agents in human beings and livestock. Although application of synthetic pesticides in agriculture gives immediate relief, it also causes well-known side effects, leading to a consensus among entomologists and agriculturists to shift towards other ecofriendly pest management methods. Natural enemies of insects including their predators, parasitoids and pathogens have attracted the attention of scientists across the globe. These natural enemies exist in agroecosystems and suppress the populations of pests. Parasitoids are farmers’ friends and the most successful group of natural enemies. Highly specialized/generalized in their prey choice, active stages of predators search for a suitable prey, attack or kill the prey and consume prey within a short handling time. Predatory ability is known to increase with increase in prey density. A single predator may devour several prey individuals. Exploiting this potency of parasitoids may yield successful results in controlling notorious pests in an ecofriendly way. This book provides information on the important biocontrol agents that are effective in pest suppression. It starts with insect parasitic groups followed by specific group of parasitoids. It is hoped that the book presents a comprehensive account of beneficial parasitoids and will be useful to undergraduate and postgraduate students of Entomology, Biological Control, Plant Protection, Agricultural Zoology and Zoology, besides those involved in competitive examinations and policy planning. Features Each chapter has been authored by specialized senior professionals Every chapter contains Learning Objectives and Points to Remember This book offers comprehensive knowledge of parasitoids and their application in pest management in a lucid way

Book Description
When the Predators choose LV-363 for a hunt and seed it with Xenomorph eggs, the result is bizarre alien hybrids and humans trapped between the Predators and their prey. The planet LV-363 teems with exotic life, including a plant growing in the shadows of its deep rifts. The plant’s flower yields a valuable narcotic, and people are forced by the cartels to harvest it. When a Yautja (Predator) ship arrives for a hunting ritual, the Predators seed the rifts with Xenomorph eggs. The aliens emerge and the result is bizarre and deadly hybrids, with humans trapped between the Predators and their prey. These deadly Xenomorph hybrids—some of which possess the ability to fly—swarm out of control and may prove more than either the Yautja or the humans can defeat. © 2021 20TH CENTURY STUDIOS

Book Description
Walker Walker was neither a Lion nor a Lion cub. He was an adolescent bursting with hormones. He was already a whimsical Butterfly painting life gay with his iridescent wings, with a wise old Owl soul within his heart of a Cow jailed by an iron Hyena heart guarded by Vultures. Walker was all, and yet, none. He managed to identify with everybody, yet not totally with anybody, even himself. But Walker was not God, as no one is, but only human that led to him rushing headlong into disaster, taking others with him, but emerging unscathed, alone, as he finally found God, himself, albeit in a form opposite towards which he had aspired. The Dark This story is about an old poor writer’s wisdom and the curiosity of a young rich boy. They knew each other only through books though they were neighbours; the boy in his mansion neighbouring the writer in his slum. The writer, writing children’s books, in which were hidden pearls of philosophy, meant only for the wise beyond their years, finally recognizes the young boy but decides to walk away from him fearing that he would hurt a young heart and mind with his old philosophy. But the smart boy manages to get the scent of the writer and follows him and finds him with the help of a young man. The circle of life is complete, but what happens next?

Book Description
Thrips (fhysanoptera) are very small insects, widespread throughout the world with a preponderance of tropical species, many temperate ones, and even a few living in arctic regions. Of the approximately 5,000 species so far identified, only a few hundred are crop pests, causing serious damage or transmitting diseases to growing crops and harvestable produce in most countries. Their fringed wings confer a natural ability to disperse widely, blown by the wind. Their minute size and cryptic behavior make them difficult to detect either in the field or in fresh vegetation transported during international trade of vegetables, fruit and ornamental flowers. Many species have now spread from their original natural habitats and hosts to favorable new environments where they often reproduce rapidly to develop intense damaging infestations that are costly to control. Over the past decade there have been several spectacular examples of this. The western flower thrips has expanded its range from the North American continent to Europe, Australia and South Africa. Thrips palmi has spread from its presumed origin, the island of Sumatra, to the coast of Florida, and threatens to extend its distribution throughout North and South America. Pear thrips, a known orchard pest of Europe and the western United States and Canada has recently become a major defoliator of hardwood trees in Vermont and the neighboring states. Local outbreaks of other species are also becoming problems in field and glasshouse crops as the effectiveness of insecticides against them decline.
