杨小舟蛾羽化节律及羽化率影响因子分析

通过野外观察和实验室可控条件下的测定,研究了杨小舟蛾蛹的羽化日节律特征和第1~4代羽化进程差异,统计了各代次羽化率和历期,分析了其羽化影响因子。结果表明:杨小舟蛾蛹羽化表现为“驼峰型”节律特征,羽化高峰出现在4:00和17:00;其1~4代蛹在相同羽化条件下羽化进程存在差异,羽化完成总虫数80%所需时间逐渐缩短,相同世代雌雄羽化高峰间隔也逐渐缩短;杨小舟蛾蛹1~4代在相同羽化条件下的平均羽化率间存在显著差异,分别为(31.41±1.16)%、(43.67±1.84)%、(38.20±1.39)%和(27.81±2.42)%;各代羽化历期存在显著差异,分别为(10.71±0.45)、(8.56±...

Summary:通过野外观察和实验室可控条件下的测定,研究了杨小舟蛾蛹的羽化日节律特征和第1~4代羽化进程差异,统计了各代次羽化率和历期,分析了其羽化影响因子。结果表明:杨小舟蛾蛹羽化表现为“驼峰型”节律特征,羽化高峰出现在4:00和17:00;其1~4代蛹在相同羽化条件下羽化进程存在差异,羽化完成总虫数80%所需时间逐渐缩短,相同世代雌雄羽化高峰间隔也逐渐缩短;杨小舟蛾蛹1~4代在相同羽化条件下的平均羽化率间存在显著差异,分别为(31.41±1.16)%、(43.67±1.84)%、(38.20±1.39)%和(27.81±2.42)%;各代羽化历期存在显著差异,分别为(10.71±0.45)、(8.56±0.17)、(6.88±0.68)、(6.43±0.66)d。羽化影响因子分析表明:不同温度和湿度处理间羽化率存在显著差异,较好的组合为光期温度(30±1)℃、暗期温度(24±1)℃,光期湿度(50±10)%、暗期湿度(70±10)%,光周期处理间差异不显著。

Micromelalopha sieversi (Staudinger) ; rhythm; emergence rate ; temperature ; relative humidity ; pho-toperiod
Based on field observation and indoor study on the eclosion rhythm characteristics, the difference in eclo- sion process from 1 st to 4th generation, the statistics of eclosion rate and the eclosion period of generations were in- vestigated. The factors impacting eclosion were analyzed by orthogonal experimental design. The results showed that the eclosion of Micromelalopha sieversi (Staudinger) showed the "hump" rhythm characteristic, one peak
