摘要: 在六种温度(20.3℃,23.9℃,27.7℃,32.2℃,33.7℃,35.9℃)及三种相对湿度范围(51.3%-55.0%RH,75.5%-76.0%RH,83.8%-85.0%RH)组合下,开展了又烟草甲 Lasioderma serricorne(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。

Abstract: 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 718-758 day-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.
