Abstract: | Summary As a result of the decrease of diurnal rearing temperature from 33 to 28°C the following phenomena were induced in adults ofSchistocerca gregaria: a) In females, a delay in the appearance of maximal levels of JH III and ecdysteroids in the hemolymph, a slowing down of oocyte growth, and an accumulation of hemolymph proteins; b) in males, a decrease of hemolymphatic JH III levels without changes in protein levels. |
