Equity in STEM Education Research In our discussions we have emphasized habitat unfavorability in terms of food shortage or climatic extremes: the relationship of migration to habitats that are only temporarily favorable in this respect, originally proposed at the 1960 International Congress, now seems well established.

Hormonal Control of Insect Migratory Behaviorare generally extremely responsive to stimuli which induce flight and less responsive or unresponsive to stimuli associated with reproduction and feeding (Kennedy, 1961). In many species migration occurs in response to short photoperiods and is an alternative to immediate reproduction. Often associa

Data obtained using the methodologies of each of these disciplines has led to an understanding of parts of the “diapause phenomenon.” This symposium has stressed the evolutionary and ecological aspects of diapause and migration as a means of escape in space and time.
