Gardiner's manufacturing and transportation advantages during the first half of the 20th century created one of the strongest local economies in the state. The city seal, adopted in 1849 when Gardiner became a city, flawlessly depicts the characteristics that shaped the community. Featured prominently on the seal is a river with falls to power manufacturing. A vessel represents transportation and trade, while an idealized city in the background reveals prosperous factories and commercial buildings. At the top is a lofty church tower, representative of the many churches in the city. Gardiner features many never-before-published postcards from the collections of the Maine Historic Preservation Commission.
Nematodes that are parasites of insects are no longer a laboratory curiosity. They have begun to be accepted as environmentally benign alternatives to the use of chemical insecticides, for the control of insect pests. Nematode worms are now applied as biological control agents against insectpests of numerous horticultural and agricultural crops. This book provides a comprehensive review of entomopathogenic nematology. It begins by reviewing fundamental biology and setting a taxonomic foundation for nematodes and their bacterial symbionts. Several chapters are devoted to functionalprocesses involved in parasitism and to nematode ecology. Later chapters describe technological advances and control methodologies.
Parasites have evolved numerous complex and fascinating ways of interacting with their hosts. The subject attracts the interest of numerous biologists from the perspective of ecology and behavioural biology, as well as from those concerned with more applied aspects of parasitology. However, until now there has been no recent book to synthesize this field.This book, written by leading authorities from the USA, Europe, Australia and New Zealand, provides the most comprehensive coverage of this important topic on the market.
