Apple-Grain Aphid, Rhopalosiphon padi LINNE (=Rhopalosiphum prunifoliae FITCH) is a common pest of rice plant, wheat, barley and many other graminae crops in Japan. In the present paper, the effects of constant temperatures on its fecundity or nymphal period were described. The aphids were reared on the potted young barley, bearing one aphid in each, in the dark condition under a considerably wide range of constant temperatures (6.0〜35.0℃); as for the relative humidity, it was not constant but was usually maintained as approximately saturated. As shown in Fig.1,the environmental temperature has a direct effect on the fecundity of apterous viviparous female ; at a temperature as low as 6.0℃. The fecundity is very small, but it increases gradually with the rise of temperature from 12.0℃ to 27.5℃, and then it decreases suddenly to the minimum level at 35.0℃. On the other hand, the effect of temperatures on the duration of each instar is as shown in Fig.2 ; any development can be scarcely observed in the first instar at 6.0℃, the longevity is shortened gradually with the rise of temperature and reaches its minimum at 25.0〜27.0℃ in 90 hours, but at temperature as high as 35.0℃, almost all nymphs die before reaching the fourth instar. As the development zero is calculated to be 6.1℃, the theoretical value of the total temperature affecting the development of this aphid seems to be 27 degree-days. The morphological variations on the body colour under the temperature from 25.0 to 32.5℃ are varied from green-blue to pale-reddish brown, but other characteristics on this species are not observed.
