| 摘 要： | 在5种温度（23．5，26．0，28．9，32．0，35．8℃）和3种相对湿度（55％RH，76％RH，93％RH）组合的情况下，对锯谷盗实验种群的生长、发育进行了研究。结果表明：在上述温、湿条件下该种群卵期为4．0－8．4d，幼虫期为10．6－23．3d，蛹期为5．4－9．8d，从产孵到成虫羽化之间的未成熟期为18．6－39．2d；卵的发育起点温度为13．4－14．8℃，幼虫为13．1－15．1℃，蛹为7．3－12．1℃，未成熟期为13．7－14．8℃；卵期有效积温71．2－80．1日度，幼虫期170．9－236．1日度，蛹期111．9－150．8日度，未成熟期为319．6－378．0日度。同时分析了温、湿度对上述生活史参数的影响，并建立了发育历期与温度的关系及发育速率与温度关系的理论模型。

| Abstract: | An ecological study on the laboratory population of Oryzaephilus surinamensis(L.)was carried out under the treatment combination of five levels of temperature(23.5，26.0，28.9，32.0，35.8℃)and three levels of relative humidity(55%RH，76%RH，93%RH).Parameters for each development stage except adult at above temperture and relative humidity range were obtained by means of statistics analysis with various rearing experiment data.It included the growth duration(d)(egg 4.0-8.4,larva 10.6-23.3,pupa 5.4-9.8,immature stage 18.6-39.2),the development zero(℃)and the total effective accumulation of temperature (day-degree) (egg 13.4-14.8/71.2-80.1,larva 13.1-15.1/170.9-236.1,pupa 7.3-12.1/111.9-150.8,immature stage 13.7-14.8/319.6-378.0).Meanwhile,the effects of temperature and relative humidity on the above parameters of life history were discussed,and the theoretical models for growth duration and development speed were constructed. |
