近几年鲁西地区部分乡镇的小麦和夏玉米发生了较为严重的麦根蝽象为害,减产明显,高达4~5成,引起了农业部门和有关专家学者的高度重视。鲁西地区在六、七十年代就有麦根蝽象的危害。那时,生产队用六六六等有机氯杀虫剂进行防治,效果较理想,该虫也降为次要害虫。由于八十年代以后放松了对该虫的防治,再加上该虫危害隐蔽,群众认识不到该虫的危害,忽视了对该虫的防治,一家一户的种植模式也使对该虫的防治效果大打折扣,近几年麦根蝽象又死灰复燃,上升为对该地区粮食生产造成威胁的害虫,成为小麦和玉米生产急需解决的问题。
In recent years, wheat and summer maize in some towns and villages in the Luxi area have been severely damaged by stinking wheat rhizosphere. As a result, the yield is obviously reduced by as much as 40% to 50%. This has aroused great attention from the agricultural departments and relevant experts and scholars. Luxi region in the sixties and seventies have the harm of stink bug. At that time, the production team used hexachlorocyclohexane and other organochlorine pesticides to prevent and control the effect is more satisfactory, the insects also reduced to secondary pests. As the 1980s after the relaxation of the prevention and control of the insects, coupled with the dangers of hidden insects, the masses do not recognize the dangers of the insects, ignoring the prevention and control of the insects, a family of planting patterns also make the insects The effectiveness of the prevention and treatment has been greatly reduced. In recent years, the stink bug has resurfaced and risen as a pest that poses a threat to the grain production in the region, making it an urgent issue for wheat and maize production.
