초록

To construct a life table and development model Schizaphis graminum (Rondani), its adult longevity and fecundity were studied at various constant temperatures ranging from 15 to 32.5℃, with 65±5% RH, and a photoperiod of 16L:8D. Adult longevity of the greenbug gradually increased with decreasing temperature below 32.5℃. Total fecundity was not significantly different at all temperatures except at 32.5℃. Daily fecundity gradually increased from 25.0℃. It was 3.6 at 27.5℃ and as temperatures either went down or up, it decreased to 1.4 at 15.0℃ and 0.4 at 32.5℃. Net reproduction rate (Ro) was highest with 47.6 at 25.0℃. The intrinsic rate of increase per day (r<SUB>m</SUB>) and the finite rate of increase per day (λ) were highest with 0.4 and 1.5 at 30.0℃, respectively and the doubling time (Dt) was shortest with 0.98 at 32.5℃. The mean generation time (T) was 8.41 at 30.0℃.
