Abstract The insecticidal efficacy of microwave irradiation against the at 12, 24, 48 and 72 h following exposure to microwave irradiations (100, 300 W) and the progeny production was assessed 45 days later. Linearly increasing irradiation power range (100, 200 and 300 W) was set up for determining mortality tendency. An increase of insect mortality caused by higher irradiation period and times elapsed after treatment has become evident commencing from 12 h after the treatment, which has significantly decreased at later elapsed time after treatment. The irradiation periods inducing the highest mortality at the examined powers were at 10 min and at 100 W power (72 h: 64.93%) and at 4.5 min. and at 300 W power (12 h: 87.01). In addition, a complete suppression of progeny production was achieved by 4.5 min treatment at 300 W power. Lognormal-type mortality process was caused by the linearly increased irradiation range. The properly chosen microwave irradiation can be used for management of Sitophilus granarius larval and adult developmental stages. This treatment could provide an effective and friendly environmental treatment technique in Integrated Pest Management (IPM) program.

不同微波辐射功率触发粮仓象鼻虫（鞘翅目：仙茅科）短期死亡率的评估

摘要 微波辐照对暴露于微波辐照（100、300 W）后 12、24、48 和 72 小时的杀虫效果和 45 天后的后代产量进行了评估。设置线性增加的辐照功率范围（100、200 和 300 W）以确定死亡率趋势。从处理后 12 小时开始，由较高的辐照时间和处理后经过的时间引起的昆虫死亡率的增加变得明显，在处理后经过的时间显着降低。在所检查的功率下诱导最高死亡率的辐照时间为 10 分钟和 100 W 功率（72 小时：64.93%）和 4.5 分钟。和 300 W 功率（12 小时：87.01）。此外，在 300 W 功率下处理 4.5 分钟可完全抑制后代的产生。对数正态死亡过程是由线性增加的照射范围引起的。The properly chosen microwave irradiation can be used for management of Sitophilus granarius larval and adult developmental stages. 这种处理可以在虫害综合管理（IPM）项目中提供一种有效和友好的环境处理技术。
