Abstract
We developed a new method for collecting eggs of Scepticus uniformis Kono without the use of sand or soil and investigated the development of the collected eggs. Weevils presented with a kidney bean leaflet and a piece of kitchen paper deposited most eggs on the kitchen paper, which proved to be a suitable substrate for oviposition. The developmental period of the eggs differed between 20 and 32°C. We estimated the lower developmental threshold(T0)as 13.9°C and the effective cumulative temperature of eggs(K)as 104.2 degree-days. It might be possible to set the timing of egg hatch by controlling the rearing temperature in the above range.
