嗜虫书虱的有效积温及气调致死作用研究
STUDIES ON THE EFFECTIVE ACCUMULATED TEMPERATURE AND LETHAL EFFECTS OF MODIFIED ATMOSPHERE ON LIPOSCELIS ENTOMOPHILAE.
【摘要】 嗜虫书虱以全面粉及酵母粉饲养时,各虫态发育速率与温度呈逻辑斯蒂曲线关系。高浓度的CO2是导致该虫死亡的主要因子,其次是温度和O2浓度。在不影响储粮品质下,适当升高仓内温度,并配以高浓度的CO2和低浓度的O2是控制该虫的最佳组合因子。
【Abstract】 Llposcelis Entomophila E.,an important insect pest to stored products,feed onthe whole flour and yeast powder(10:1),was determined under 18℃,20℃,25℃,28℃.30℃,32℃ and 35℃,The results showed that the developmental rate curve of this insectwas the shape of a sigmoid,and four logistic models between developmental rate and temperature were established.The developmental zero temperature and effective accumulatedtemperature of different developmental stage were estimated by direct optimum methodsrespectively.In addition,the acute lethal effects of the different level combination of tem-perature,carbon dioxide and oxygen on this insect using orthogonal combination design.The results showed that high CO2 concentration was the most important factor that restilted in the mortality of this insect,temperature was the second,and low O2 concentrationwas the last.Considerably higher temperature combined with high CO2 and low O2 was op-timum for controlling this insect to maintain high quality of grain.
