The rate (100/Weeks) of adult development at a series of constant temperatures after development has begun. The response of previously unchilled pupae (circles) cannot be distinguished from that of previously chilled pupae (triangles). the constant temperatures within the range 2y2 to 30° C. Indeed, at 21/2° C. adult development never began, and pupae at this temperature invariably died after about a year. In the lower curve in Figure 1 the results have been computed and plotted on a rate (I/Time) basis. The relatively minor effects of temperature are here clearly evident. Even these minor effects are paradoxical in that the rates encountered at 20° and 25° C. are actually lower than those at 10° and 15° Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
