稻飞虱是同翅目飞虱科害虫，主要有褐飞虱、灰飞虱和白背飞虱等，它们可以远程迁飞繁殖为害。稻飞虱通过刺吸式口器，吸取水稻汁液，为害水稻的同时，还能够传播病毒，轻则造成水稻减产，重则造成水稻绝收。由于受气候条件、水稻品种及耕种方式等多种因素影响，稻飞虱已成为长江中下游稻区主要虫害，常为中等发生程度。 目前，稻飞虱的防治还需依靠化学药剂，因此，稻飞虱防治药剂及防治技术是水稻高产稳产的保证。稻飞虱防治药剂种类繁多，有抗生素类杀虫剂阿维菌素，有机磷类的毒死蜱、稻丰散，吡唑类的乙虫腈，氨基甲酸酯类的异丙威，新烟碱类的吡虫啉、噻虫嗪、啶虫脒、烯啶虫胺以及吡蚜酮、噻嗪酮等。本文对吡虫啉、噻嗪酮、烯啶虫胺、噻虫嗪及吡蚜酮等5种防治稻飞虱常用药剂的开发及专利、作用机理及应用、抗性、药效、剂型及复配、工艺和市场等分别进行探讨，以期为生产上防治稻飞虱、厂家开发稻飞虱产品提供参考。

7月，农林牧投资增速小幅增长，渔业投资增速下降。市场价格方面，屠宰企业提价收购，生猪价格整体上涨；玉米加工企业提价补库，玉米价格强势走高；大豆下游需求不足，市场价格持续走低；纺织企业销售订单少，棉花需求量低，棉花价格跌跌不休。预计8月，受夏季炎热多雨天气影响，生猪外运以及收购较为困难，生猪市场供应整体偏紧，生猪价格将继续保持坚挺；在新玉米上市前，流通环节供应不足，玉米价格仍将上行；国储拍卖将继续，大豆供应压力增加，价格将继续下降；新棉即将陆续上市，棉花供应增加，需求难见好转，市场价格或将继续承压下降。

This study evaluated the toxicity and duration of 3 residual insecticides against the Old World sand fly, Phlebotomus papatasi, an important vector of cutaneous leishmaniasis, on 2 types of tent material used by the US military in Afghanistan and the Middle East. Vinyl and cotton duck tent surface were treated at maximum labeled rate of lambda-cyhalothrin (Demand CS, Zeneca Inc, Wilmington, DE) bifenthrin (Talstar P. Professional, FMC Corportation, Philadelphia, PA) and permethrin (Insect Repellent, Clothing Application 40, then subsequently stored in indoor, shaded space at room temperature 60-70relative humidity (RH) 22 degree C-25 degree C) and under sunlight and ambient air temperatures outdoors (20-30RH, 29 degree C- 44 degree C) Insecticide susceptible colony flies (F110) obtained from the insectary of US Navy Medical research Unit No. 3, Cairo, Egypt, were exposed to treated tent surfaces for 30 minutes periods twice monthly for up to 5 months, then once monthly thereafter, using the World Health Organization cone assay Lambda-cyhalothrin treated cotton duck tent material stored indoors killed P. papatasi for 8 months, while the complementary sun- exposed cotton duck material killed adult flies for 1 month before the efficacy dropped to less than 80.
