The average peak weight and standard deviation (SD) for each strain are shown. W_{0}, initial weight of fifth instar larvae; CW, critical weight; ICG, interval to cessation of growth, that is, the interval between attainment of the critical weight and the secretion of PTTH; GR, growth rate; W(t), weight at time t (2.5 days in all cases reported here).
