摘要
在恒温条件下 ,观察了不同温度对豆突眼长蝽ChauliopsfallaxScott生长发育的影响 ,用直接最优法和直线回归法分析数据 ,结果表明直接最优法能较好地反应实际情况。卵、1~ 5龄若虫和整个若虫期的发育起点温度分别为 7 98℃ ,7 1 6℃ ,6 5 3℃ ,8 81℃ ,6 75℃ ,8 2 7℃和 7 5 0℃ ,有效积温分别为85 8,60 8,5 2 0 ,71 4,1 0 1 5 ,66 3和 3 5 3 0日·度 ,发育速率最大时的温度分别为 3 4 84℃ ,3 4 48℃ ,3 4 1 6℃ ,3 4 1 2℃ ,3 4 75℃ ,3 5 1 1℃和 3 3 65℃。
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.
