Book Description
The genus Malacosoma Hubner, the tent caterpillars, is a group of lasiocampid moths restricted to the temperate regions of the Northern Hemisphere. The adults are often ignored, possibly because they are quite abundant (collectors tend to save rare or unusal specimens), are moderate in size, comparatively drab in color, and have a lifespan of only a few days at most. The larvae, however, are well known for the conspicuous tents which some species construct in early spring soon after the first leaves appear.

Biological Control
Author: C. Huffaker
Publisher: Springer Science & Business Media
ISBN: 1461565286
Category : Science
Languages : en
Pages : 525
Book Description
The explosive increase in the world's human population, with conse quent need to feed an ever-increasing number of hungry mouths, and the largely resultant disturbances and pollution of the environment in which man must live and produce the things he needs, are forcing him to search for means of solving the first problem without intensifying the latter. Food production requires adequate assurance against the ravages of insects. In the last three decades short-sighted, unilateral and almost exclusive employment of synthesized chemicals for insect pest control has posed an enormous and as yet unfathomed contribution to the degradation of our environment, while our insect pest problems seem greater than ever. Properly viewed, pest control is basically a question of applied ecology, yet its practice has long been conducted with little regard to real necessity for control, and in some cases, with little regard to various detrimental side-effects or long-term advantage with respect, even, to the specific crop itself. This book deals fundamentally with these questions. The development of pesticide resistance in many of the target species, against which the pesticides are directed, has occasioned an ever-increasing load of applications and complexes of different kinds of highly toxic materials. This has been made even more "necessary" as the destruction of natural enemies has resulted, as a side effect, in the rise to pest status of many species that were formerly innocuous. The application of broad-spec trum pesticides thus has many serious and self-defeating features.

Bird Nests and Construction Behaviour
Author: Mike Hansell
Publisher: Cambridge University Press
ISBN: 9781139429085
Category : Science
Languages : en
Pages : 302
Book Description
Bird Nests and Construction Behaviour provides a broad view of our understanding of the biology of the nests, bowers and tools made by birds. It illustrates how, among vertebrates, the building abilities of birds are more impressive and consistent than for any other builders other than ourselves, yet birds seem to require no special equipment, and use quite uncomplicated behaviour. In doing so, the book raises general issues in the field of behavioural ecology including the costs of reproduction, sexual selection and the organisation and complexity of behaviour. Written for students and researchers of animal behaviour, behavioural ecology and ornithology, it will nevertheless make fascinating reading for architects and engineers interested in understanding how structures are created by animals.

Social Insects V2
Author: Henry Hermani
Publisher: Elsevier
ISBN: 0323147828
Category : Science
Languages : en
Pages : 506
Book Description
Social Insects, Volume II is essentially a continuation and review of topics covered in Volume I. The main focus of this volume is on the systematic of eusocial hymenoptera and the closely associated realms of presocial insects and social non-insectan arthropods. Consisting of five major chapters, this volume starts with the chapter on the enemies and defense mechanisms of termites. Several mechanisms are discussed in this chapter, such as defense by the nest, workers, and soldiers. Chapter 3 focuses on presocial insects and a comparison of parental care without nests and based on nests. Chapter 4 discusses the sociality of Arachnida and emphasizes the patterns and evolution of sociality in Arachnida, particularly spiders. Two chapters discuss the social hymenoptera, including its defensive mechanisms and its systematics. This volume will be of great help to students and professionals in the field of entomology, biology, and zoology.
