摘　　要： 采用滤纸载药熏蒸法,测试了不同温度处理条件下小茴香精油在空仓和实仓两种模拟条件下对谷蠹成虫的熏杀活性。结果表明,小茴香精油在空仓模拟条件下对谷蠹成虫的熏杀活性好于实仓。在30℃条件下,小茴香精油6.67μL/L空仓处理试虫48 h、100.00μL/L实仓处理谷蠹成虫7 d,试虫的校正死亡率均为100%。此外,小茴香精油对谷蠹子代种群也具有较强的控制作用。 The fumigant activities of essential oil from Foeniculum vulgare seeds against adults of Rhizopertha dominica（Fab.） were tested by drug-paper method in simulation warehouses.When the pests were not fed with wheat kernels,the F.vulgare essential oil showed better fumigant activities than those fed with wheat kernels.When the non-fed pests were exposure by drug vapor with 6.67 μL/L for 48 h and pests fed with wheat were exposure by drug vapor with 100.00 μL/L for 7 d at 30 ℃,the corrected mortalities of R.dominica were both 100%.Furthermore,the F.vulgare essential oil could effectively restrain the R.dominica of next generation.
