储粮病虫综合防治

THINKING ON THE INTEGRATED CONTROL FOR STORED PRODUCT PESTS

在储藏产品保护中 ,化学防治是一项必需的防治技术 ,由于害虫对药剂抗性的发展以及药剂残毒和对环境的影响等因素 ,降低了化学防治的作用 ,有必要进一步研究改进 ,并通过分析经济损害水平和经济阈值模式来合理实施化学防治。综合防治或有害生物综合治理是储藏物保护的一个方向 ,在实践中 ,已有采用各项措施协调配合防治储藏物病虫的经验 ,值得进一步总结 ,更好地贯彻“以防为主、综合防治”的储粮保护方针。

Chemical control in management of the stored product pest in China will continue to play an indispensable role,the technology must be used widely and well and this can only be done with a complete understanding of the factors affecting their use and effectiveness. As we are aware that the economic and ecologic information or methodology available to enable assessment of cost and environmental benefits of the technique.The models of economic injuring level(EIL) and economic threshold (ET) are indispensible to provide the data necessary for rational planning of stored product pest control operations. Moreover ,synthetic control or integrated pest management (IPM) will be developed in the foreseeable future,alternative technologies for stored product pest control have been described elsewhere in seminars and conferences,most offer considerable promise but involve capital input which may be quite substantial,as chemical and non-chemical techniques as well as optimal management in storage processes,choices have to be made as to which technologies,if any or all,are to be integrated into the storage and handling system.
