摘要
鉴于镶嵌式防治不适用于营孤雌生殖的菜蚜无翅成蚜，于是作者对镶嵌式防治在时空上稍作微细的改变，即先以作用机理不同的杀虫剂Ａ和Ｂ可不同区域作镶嵌式的喷洒，而后在下一次作交替防治，这相当于邻近区域间存活个体的互相迁飞。我们称此法为镶嵌式交替防治。在上海梅陇地区，自１９８５年以来使用这一策略防治菜缢管好（Ｌｉｐａｐｈｉｓｅｒｙｓｉｍｉｐｓｅｕｄｏｂｒａｓｓｉｃａｅ）、桃蚜（Ｍｙｚｕｓｐｅｒｓｉｃａｅ）和柳二尾蚜（Ｃａｖａｒｉｅｌｌａ ｓａｌｉｃｉｃｏｌａ）。根据生物测定和单个蚜虫的酯酶活性测定，在分别与连续使用乐果直至无效，然后改用氰戊菊酯防治的菜蚜种群比较时，所得结果表明，乐界和氢戊菊酯的镶嵌式防治能延缓这些菜蚜抗性的产生。
he mosaic control with insecticides seems not suitable for insects such as aphids which reproduce by parthenogenesis and have low mobility in apterous form. Inthe present study we adopted another strategy by spraying unrelated insecticides atfirst and then exchanging or rotating the spraying in different areas in next terms.Since 1985, this strategy has been adopted to control the aphids on vegetables inMeilong, a suburban county of Shanghai. The aphids included Lip -phis erysimi pseudobrassicae, Myzus persicae and Cavariella salicicola. Based on bioassay and determination of -Na esterase activity in single aphids, we found mosaic rotation of dimethoate and fenvalerate can delay the development of insecticide resistance in theabove three species of aphids, as compared with continued use of dimethoate followedby continued use of fenvalerate to the point where control was impaired by resistance.
