摘　　要：环流通风技术通过对粮仓内温度、湿度、粮食水分的控制可以达到调控书虱种群的效果。为深入探究以上可操控的环流通风环境因子对嗜卷书虱种群发展的影响,本研究开展了不同温度、湿度和粮食水分的梯度实验来探究该问题。结果表明,嗜卷书虱在较低温度(20℃)无法生存,随着温度升高(>25℃)书虱种群增殖加快。在30℃环境温度下,书虱在较低相对湿度(43%)下无法生存,随着环境相对湿度增加,书虱繁殖数量逐渐增加,但在较高相对湿度(79%)下繁殖数量降低;25℃下,随着相对湿度增加,书虱繁殖数量始终持续增加。对于粮食含水量,低水分粮食比高水分粮食书虱增殖少。以上结果说明温度、湿度和粮食含水量是调控书虱增殖的重要因素,为后续开展环流通风控温控湿工艺宏观防控书虱提供了理论依据。Through the controlling of temperature,relative humidity and grain moisture content in grain silos,cir-culation ventilation technology plays a vital role in regulating the booklice population.To further explore the effects of the above controllable circulation ventilation environmental factors on the population proliferation of Liposcelis bostrychophila,a gradient experiment with different temperatures,relative humidity and grain moisture content was conducted.The results found that L.bostrychophila were unable to survive at low temperature(20℃),and the population of L.bostrychophila accelerated with the increasing of temperature(25C):Under the temperature of 30℃,L.bostrychophilawereunableto surviveat lowrelativehumidity(43%),and with therisingof theenviron-ment humidity,the number of L.bostrychophila,kept increasing but decreased in high relative humidity(79%).At 25℃,thereproduction number of L.bostrychophilacontinued to increasewiththerisingof relativehumidity.As for grain moisture content,grain with low moisture cultivated fewer L.bostrychophila than grain with high moisture.The results demonstrated that temperature,relative humidity and grain moisture content are vital factors in the popula-tion regulation of booklice and provided a theoretical basis for the subsequent application of circulation ventilation technology in the macro prevention of booklice.
