| 摘要: |
| 虫害导致的农产品储藏损失率很高。化学熏蒸杀虫易产生环境污染和毒素残留，安全性较差，而射线辐照杀虫引起品质劣变。射频技术作为一项新的技术，因独特的选择性加热和高穿透力等优势，将广泛应用于传热困难、热敏性农产品的产后虫害控制领域。综述目前国外在这方面的研究进展，重点介绍存在的问题。最后，分析国内开展该技术研究的重要性和迫切性，并对今后的研究方向提出建议。 |

| Abstract: |
| A major problem in agro-product storage is the infestation of insect pests.Present quarantine treatments for domestic markets include chemical fumigation and ionizing radiation.The need to replace those methods becomes more urgent because of concerns about the health hazards of chemical pesticides and its environment pollution.An innovative technique using radio frequency (RF) heating can extend storage with low cost and good quality of agro-product, especially for those with low heat transfer coefficient and its quality susceptible to heat.The objectives of this review were firstly to introduce the recent advances on the post-harvest pest control of agro-product abroad, then to analyze the existing problems in particular and finally to prospect a tendency and significance of possible practical application of RF treatment for agro-product insect control in China. |
