On the rate of completion of Diapause Development At Constant Temperatures in the Eggs of Gryllulus Commodus Walker

Abstract

The median duration of low-temperature treatment required by the eggs of G. commodus in order that they may develop and hatch without interruption due to diapause was least at 12.7°C., slightly longer or about the same at 15.9°C., and considerably longer at 1O.3°C. At S.5°C. it was not found possible to obtain 50 per cent. of the eggs free from diapause.
