摘要
在六种温度（２０．３℃，２３．９℃，２７７℃，３２．２℃，３３．７℃，３５．９℃）及三种相对湿度范围（５１．３％～５５．０％ＲＨ，７５．５０～７６．０％ＲＨ，８３．８％～８５．０％ＲＨ）组合下，开展了对烟草甲Ｌａｓｉｏｄｅｒｍａｓｅｒｒｉｃｏｒｎｅ（Ｆ．）实验生态的系统研究，获得其在不同温、湿度组合情况下生长发育、生存和繁殖的一系列特性和参数，包括各虫态发育历期、存活率、发育起点温度、有效积温和平均繁殖力等，并建立了发育历期、发育速率、存活率及繁殖力的理论模型。
An ecological study on the laboratory population of cigarette beetle,Lasioderma serricorne, was carried out under the treatment combination of six levels of temperature (20.3 ℃, 23.9℃, 27.7 ℃, 32.2℃, 33.7℃, 35.9℃) and three levels of relative humidities (51.3% ￣ 55.0% RH, 75.5%￣76.0% RH, 83.8%￣85.0% RH). parameters for development, survival and fecundity of cigarette beetle laboratory population were obtained by means of statistics analysis in various rearing experiments. The temperature range for development is 14℃￣36 ℃, the most optimal temperature and relative humidity are 30 ℃￣ 34 ℃, 70%￣85% RH, the generation duration is 35￣128 days, the total effective temperature is 718￣ 758day-degree, and the average numbers of eggs laid by females are 6￣97. The temperature higher than 36℃ and relative humidity less than 51% have adverse influence on survival. Finally, the theoretical models for growth duration,development speed, survival rate, fecundity were constructed.
