Borror and DeLong-s Introduction to the Study of Insects

5 stars (Important for both biologists and non-biologists) - Everything about insects is fascinating, and this book gives a comprehensive overview of their behavior, anatomy, and classification. For non-experts in entomology, such as this reviewer, the book provides the necessary background for further study. Topics such as the molecular genetics of insects and the genetic engineering of insects are not covered, but there are plenty of other books that treat these topics in detail. Only the first four chapters were read by this reviewer, but only chapter four will be discussed here. Early on in chapter four, the authors dispel the prejudice that since insects have small nervous systems and have short life spans, they are not automatons and can exhibit a remarkable degree of spontaneity. Insects can adjust to the circumstances of their environment and the organization of their activities can be extremely complex. What is most interesting about their discussion of insect behavior is the emphasis on how it depends on the internal state of the insect, and not only its nervous system but also its internal organs. The authors view the basic unit of behavior in an insect as being a `refle'x. A receptor that is stimulated will cause a particular group of insects to contract, which is observed as a body movement of the insect. A `releaser' is the stimulus that actually triggers a specific collection of movements. This results in what is called a `fixed-action pattern', which, as the name implies, occurs the same way every time it occurs. To be contrasted with these are the `modal-action patterns' that adapt to changes in the body position of the insect relative to external objects. A `central pattern generator' the authors write, is responsible for the leg and wing movements of insects, and allows them to navigate in noisy environments. All of these considerations of insect behavior are interesting in themselves, but even more so considering that they are being applied t...

Insects That Feed on Trees and Shrubs

5 stars (Well worth it!) - This book is on my "short list" of essential references. Species are covered in clear, concise descriptions. This well organized volume makes hunting for similar species as easy as turning a page. The photos? I can't say enough about the clear, photos that make insect identification a good deal easier! While an excellent book for the landscape professional, scientist, or advanced gardener, beginners might be a bit overwhelmed by the technical language and scientific names. 5 stars (This is a much needed and fabulous manual.) - When trying to identify a particular problem with growing trees or shrubs knowing what kinds of insects are possible culprits is a major step. This book gives us, in color photos and descriptions, most of the common larvae that can be found feeding on the particular plants. Even Entomology texts often refuse to deal with larvae of insects, keeping only the adults in the keys and descriptions (even though the adults are often not pests!). This guide will be a welcome addition to any plant clinic, grower, or Entomology professor or student's bookshelf. ...
