This paper mainly investigated the influence of temperature on the egg diapause of Telegryllus emma collected near the area of Sihong,Jiangsu Province and also tested the effects of low and high temperature on the diapause of Telegryllus emma.

A series of experiments were performed in different populations and species of Daphnia to investigate: 1) genetic and environmental controls of SR and revival of diapausing eggs; 2) the photoperiodic responses of SR in closely related species inhabiting overlapping but different micro habitats; 3) the genetic consequences of SR on populations genetic architecture (genotypic mean and geneti.
