| 中文摘要: |
| 在19、21、23、25和27℃共5个恒温条件下, 研究测定了灰茶尺蠖各虫态的发育历期、发育起点温度和有效积温。结果表明, 在19～27℃范围内, 灰茶尺蠖各虫态和世代的发育历期随着温度的升高而显著缩短, 除成虫外, 卵、幼虫、蛹和世代的发育速率与温度呈极显著正相关(P<0.01)。灰茶尺蠖卵、幼虫、蛹、成虫和世代的发育起点温度分别为(9.78±1.20)、(4.57±1.52)、(7.15±1.21)、(14.91±2.83)和(6.93±0.47)℃, 有效积温分别为(88.01±7.81)、(311.26±25.35)、(150.13±11.29)、(34.50±11.54)和(570.03±16.29)日·度。 |

| The developmental duration, developmental threshold temperature and effective accumulated temperature of Ectropis grisescens Warren were investigated under five constant temperatures (19, 21, 23, 25, 27℃). The results showed that the developmental durations of different stages and whole generation of E.grisescens became shorter with increasing temperature from 19 to 27℃, and the correlation between the developmental rates of eggs, larvae, pupae and whole generation and temperature were significantly positive correlation at 0.01 level except adults. The developmental threshold temperatures of eggs, larvae, pupae, adults and whole generation were (9.78±1.20), (4.57±1.52), (7.15±1.21), (14.91±2.83) and(6.93±0.47)℃, respectively, and their effective accumulated temperatures were (88.01±7.81), (311.26±25.35), (150.13±11.29), (34.50±11.54) and (570.03±16.29) degree-day, respectively. |
