Print on Demand. This book examines the correlation between temperature and the development of insects. This relationship had previously been noted and studied, but the author sought to determine whether a constant threshold of development could be experimentally demonstrated and, if so, the method for its determination. The author also sought to answer to what extent a constant thermal constant—the total of effective temperatures expressed over the period of developmental time—could be established for different species, and to compare the effects of constant versus variable temperatures on growth and development. The book draws on previous research in the field of insect development and includes an array of tables and graphs that provide experimental data to support the discussion. The author concludes that a constant threshold of development can be determined and that the thermal constant does provide a useful framework for understanding insect development across different constant temperatures. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.…

Investigators early in the modern scientific era recognized the influence which temperature exerted upon the rate of growth in plants. Reaumur, as early as 1735, recognized this relation as a quantitative one and suggested the idea that the total amount of heat, expressed as temperature summations, required to produce a given growth effect, was a constant. The method of summation, as used by Reaumur, assumed that temperatures above the zero of his thermometer, i. E., the freezing point of water, were effective while those below zero were not.
Variations in the experimentally determined thermal constants were later associated with the effect of other climatic factors in the processes of growth and led to the search for more accurate meth ods for the summation of temperatures. Credit appears to be due de Candolle (1832, wide de Candolle 1855) for the statement that effective temperatures do not necessarily persist down to zero but that some point above zero should often be used as the basis for summations of the thermal increment.
From the time of de Candolle's early work progress for some fifty years was mostly in the line of accumulation of statistics in which many investigators participated.
