Abstract
具有如下结构式I的1,4-二芳基-2-氟-2-丁烯杀虫化合物及包含这些化合物的组合物和防治昆虫和螨虫的方法。
Description
发明背景
昆虫和螨类损害生长中的和收获的作物。在美国,农作物必须与成千上万种害虫竞争。尤其是,烟草夜蛾幼虫和亚热带粘虫对作物特别有害。
烟草夜蛾幼虫引起作物极大的经济损失。特别是,烟青虫以青铃为食而破坏棉花作物。烟青虫的防治是麻烦的,因为它们对很多杀虫剂(包括有机磷、氨基甲酸酯和拟除虫菊酯)具有抗药性。
如今虽然可购得市售的杀虫剂和杀螨剂,但昆虫和螨无论对生长中的或收获的作物引起的损害都存在。因而需不断地进行研究以产生新的、更有效的杀虫剂和杀螨剂。
已知一些氟代烯烃具有杀虫和杀螨活性(见如U.S.5,248,834;GB2,288,803-AWO94/06741)。GB2,288,803-A和WO94/06741所揭示的化合物在本发明的范围之外。U.S.5,248,834一般性地揭示了一些1-芳基-1-(3-芳基-1-氟代丙烯-1-基)环丙烷化合物。然而该专利并未提供制备任何氟代烯烃化合物的方法。
因此,本发明的一个目的是提供对害虫和螨类防治有高效的化合物。
本发明的另一个目的是提供防治害虫和螨类的方法。
本发明的进一步目的是提供保护生长中的和收获的作物不受昆虫和螨的攻击和侵扰所引起的损害。
本发明的这些目的及其它目的将由本发明的下述详述而更明了。

受试化合物的杀虫和杀螨活性评估
将受试化合物35%丙酮溶液用水混合溶解以制得浓度为10,000ppm的受试溶液。然后按需用水稀释。
亚热带粘虫:三龄期幼虫,亚热带粘虫(简称SAW)
将展开成7-8cm长的菜豆叶浸入受试溶液,搅动3分钟,使其在罩中干燥。然后将叶子放在底部含有湿滤纸,并有10条3龄期幼虫的100×10mm陪替氏培养皿中。5天后,观察死亡率、噬食的减少或对正常蜕皮的干扰。
玉米幼芽根叶甲:3龄期玉米幼芽根叶甲(简称WCR)
将1cc细滑石粉放入30ml广口螺口玻璃瓶中。将1ml适当的丙酮受试液滴在滑石粉上,使每瓶有1.25mg活性成分。将瓶放在温和的空气流中,直至丙酮挥发。将干燥的滑石粉弄松,每瓶加入1cc小米籽作为幼虫的食物,并加入25ml湿土。将瓶加盖,将内容物作充分的机械混合。然后,每瓶中加入10条3龄期幼虫,将瓶松松地盖上,使幼虫能进行空气交换。处理5天,这时进行死亡率计数。幼虫消失被认为是死亡,因为它们很快分解,不能再找到。本实验中所用的活性物质的浓度约相当于50kg/公顷。
烟芽夜蛾(Heliothis vienscens):3龄期烟芽夜蛾(简称TBW)
将棉叶浸入受试溶液,使其在罩中干燥。干燥后,每张切成4等分,将10段分别放在含有5-7mm长的牙科湿纱布条的30ml医用塑料杯中。每个杯中加入1条3龄期幼虫,将卡纸板盖放在杯上。
处理维持3天,然后进行死亡率计数,并进行噬食损害减少的估测。
豆卫矛蚜:混龄幼虫豆卫矛蚜(简称BA)
在实验前一天,将含有高约5cm的一株旱金莲属植物(
Tropaeolum sp.)用约100-200条盆用蚜虫寄生。在罩中,每盆以4rpm可旋转地喷以受试溶液2轮。喷雾达到完全覆盖植物和蚜虫。将喷过雾的盆在白色盘上放在一边2天,然后进行死亡率计数。
普通红叶螨(OP抗性品系),2-点叶螨(简称TSM)
选择具有扩展成7-8cm的初生叶的菜豆,分成每盆一株植物。从主株上取下的寄生叶上割下一小片,放在受试植物的每个叶片上。这在处理前2小时进行,以使螨爬到受试植物上产卵。割下的寄生叶的大小是各异的,每个叶上得到约100个螨。在试验处理时,取出用于转移螨的叶片,弃去。将新寄生的植物浸入搅动的受试溶液3秒,放在罩中干燥。2天后,取出一片叶,进行死亡率计数。按下面所示的计分法对试验进行评估,所得数据见表I。
对应用于上述评估的化合物给予化合物编号和根据名称来鉴定。表I报告的数据被化合物编号列出。
