摘　　要：嗜虫书虱是一种危及食品安全的世界性害虫,已成为我国“三低(低温、低氧、低剂量)”储藏条件下的优势害虫种群。为探讨嗜虫书虱对温度胁迫的响应,研究了低温环境(5.0、8.0、11.0、14.0、17.0、20.0℃)和高温环境(35.0、37.5、40.0、42.5、45.0、47.5℃)对嗜虫书虱生长发育与繁殖能力的影响。结果表明,14.0℃以下的低温和40.0℃以上高温处理对嗜虫书虱存活均有显著影响。其中,11.0℃的低温处理6 d后,嗜虫书虱成虫死亡率不再随处理时间显著增加。高温47.5℃处理160 min后嗜虫书虱成虫全部死亡,说明了高温短时处理可以有效防治嗜虫书虱。低温5.0℃胁迫处理3 d后嗜虫书虱卵的孵化率为55.56%,高温45.0℃处理120 min后其孵化率为51.11%,说明卵对高温胁迫和低温胁迫均有较强的耐受能力。高温35.0~45.0℃处理120 min、低温8.0~20.0℃处理3 d后,嗜虫书虱的平均产卵量、F 1代孵化率无显著变化,因此,温度胁迫处理对嗜虫书虱繁殖能力没有显著的影响,这也可能是书虱爆发成灾的主要原因。Liposcelis entomophila(Enderlein)is a worldwide pest that endangers food safety.It has become the dominant population of pests in China under the conditions of low temperature,low oxygen storage and low dose of pesticide.This study simulated the low temperature environment(5.0℃,8.0℃,11.0℃,14.0℃,17.0℃,and 20.0℃)and high temperature environment(35.0℃,37.5℃,40.0℃,42.5℃,45.0℃,and 47.5℃),and investigated the effect of temperature stress on the development and reproduction of L.entomophila.The results showed that the low temperature treatment below 14.0℃and the high temperature treatment above 40.0℃had significant effects on the survival of L.entomophila.There was no significant effect on the mortality of the adults with the increase of treatment time at 11.0℃,which indicated that L.entomophila has adaptability to low temperature.All adults of L.entomophila were killed after being treated at a high temperature of 47.5℃for 160 min,indicating that the short-term treatment at high temperature could effectively control L.entomophila.The hatching rate was 55.56%and 51.11%,respectively for L.entomophila treated at 5.0℃for 3 days and those treated at 45.0℃for 120 min.The eggs had strong tolerance to high and low temperature stress.After treatment at high temperature of 35.0-45.0℃for 120 min and low temperature of 8.0-20.0℃for 3 days,the egg amount and F 1 hatching rate of L.entomophila were not changed significantly.The results demonstrated that temperature stress treatment could not significantly influence the reproduction ability of L.entomophila,which might be the main cause of the L.entomophila outbreak.
