| Abstract: | The developmental rate of Chaulipos fallax Scott was determined at 6 constant temperatures. The optimum seeking method was superior to the linear regression method in the analysis of experimental data. The threshold temperatures for eggs, 1st～5th instar nymphs and the whole nymph stage were estimated to be 7 98,7 16,6 53,8 81,6 75,8 27 and 7 50℃, and the effective temperature sums for these stages were assessed as 85 8, 60 8, 52 0, 71 4, 101 5, 66 3 and 353 0 degree day, respectively. The temperatures at which the maximal rate would be reached in these stages were 34 84,34 48,34 16,34 21,34 75,35 11 and 33 65℃, respectively. |
