摘要: 地下害虫是我国重要农林害虫,分布遍及全国,为害相当严重。自1982年原农业部在河南洛阳召开了全国防治地下害虫座谈会后,各地大力开展防治,取得很大进展(有关科研的进展作者曾在本刊1979年4期作过介绍),现仅就近年地下害虫的发生动态,与有关防治意见综述如下。 地下害虫发生概况 自1975年以来,作者先后赴10余省(区)调查,并通过信息了解,目前我国地下害虫发生的情况是: 1.蛴螬为害仍居首位 全国各地一般蛴螬为害均较突出,不少地区调查占总虫量70—80%以上,如1983年河南30个县调查,蛴螬占86.3%。主要为害粮食(小麦、玉米、薯类)、油料(大豆、花生)、甘蔗、药用植物(贝母等)、蔬菜、林木苗圃的树苗、以及绿地、草坪等。
