| 摘要: |
| 在17～30℃内共设7个温度,测定了核桃举肢蛾越冬幼虫化蛹和羽化的发育起点温度,分别为9.4,10.4℃。发育积温分别为276.3和196.3日度,表明温度影响过冬幼虫化蛹和羽化发育速度。土壤含水量低,化蛹率和羽化率均低;在温度条件满足时,土壤含水量低,发育历期延长,存活率降低。此外还建立了8个回归方程式。 |

| Abstract: |
| Seven different temperatures were used to determine the starting
temperature for pupation and eclosion of the overwintering lavae of Atrijuglans hetaohei
Yang.being 9.4℃ and 10.4℃ respectively,whose effectively-accumulated temperatures
for their development were 276.3℃/d and 196.3℃/d respectively.Soil temperature
affects the developing speed of pupation and eclosion process.When water content in soil
is low,and so is pupation and eclosion rate.When the temperature condition is
favourable but soil water content is low,the development process is prolonged,and the
survival rate is deereased.In addition,eight regression equations were also established in
the present study. |
