$14.00 Regular price $20.00

A fact of life is that many people who love nature are turned off by the word electromagnetic. Any naturalist; amateur or professional must have a down to earth understanding of the electromagnetic spectrum. The entire spectrum is covered in this book, everything from the short radioactive waves used to sterilize male screw flies so the female lays sterile eggs; to the long-wave radio frequencies that penetrate the soil, control and enhance root growth and the immune system of plants and animals. Explains not only the visible-light spectrum, but also the invisible high-energy nuclear and low-energy infrared and radio portions of the electromagnetic spectrum.

Copyright 1994, softcover, 178 pages. 52 per case.

Not what I was expecting

This book was disappointing, not what I was expecting anyway. There was very little information regarding how insects see things, from a spectrum stand point. I would not recommend it.
