Abstract
In pregnant females of the viviparous cockroach, Nauphoeta cinerea (Ol ivier 1789), mass specific metabolic heat flux was significantly reduc ed compared to males and non-pregnant females. This means that energet ic demands during gestation do not translate into an increase in energ y of metabolic rate. The reduction possibly cannot be put down to the fact, that the locomotor activity of N cinerea is considerably reduced during pregnancy.
