摘要
利用恒温水浴槽对桔小实蝇的卵(16+2h)、1龄幼虫(48+2h)和非取食3龄老熟幼虫进行不同温度和时间组合的热水浸泡处理,分别利用热动力学模型、机率值模型、Logit模型和Log-Log模型对死亡率与处理时间的关系进行了分析比较,以明确最佳分析数学模型和热处理最耐受虫态。试验结果表明:热动力学模型为预测热处理致死时间的最佳数学模型;在44℃、45℃和46℃等温度条件下,桔小实蝇卵的耐热能力最强,其次为1龄幼虫,3龄幼虫耐热能力最差。该结果为利用热水浸泡处理等热处理技术对桔小实蝇进行检疫处理奠定了基础。
Abstract Eggs( 16 + 2h ), 1^st,(48 + 2h)and late 3^rd instars larvae of the oriental fruit fly Bactrocera dorsalis (Hendel) were subjected to hot water immersion at different temperatures and holding times. The relationship be- tween mortality and holding time were separately analyzed with four mathematic models of the thermal death kinetic, Probit, Logit and Log - Log, so as to clarify the most suitable model for thermal tolerance analysis and find out the most tolerance life stage. Results showed that thermal death kinetic model was the best model in prediction of thermal lethal time and the egg of the oriental fruit fly was the most tolerance stage in hot water immersion treat- ment at the temperatures of 44℃, 45℃ and 46℃, following was the 1^st and 3^rd instar larvae. These results could be used as a basis for the establishment of phytosanitary treatment of the oriental fruit fly with hot water immersion technologies.
