| 摘 要： | 已知迭部林区苗圃金龟子种类17种,隶属于2科,10属。构成严重为害的种类有小云斑鳃金龟Polyphylla gracilicornis、粗绿彩丽金龟Mimela holosericea、大栗鳃金龟Melolontha hippocastani mongolica等。小云斑鳃金龟4年发生1代;粗绿彩丽金龟1年发生1代;大栗鳃金龟6年发生1代。苗木种类单一、定植时间长,导致圃地不能及时休闲轮作及施用未经充分腐熟的有机肥是造成害虫发生的主要原因。成虫出土羽化高峰期在苗圃地设置250W高压汞灯对其成虫进行诱杀,当年虫口密度下降52.63%,苗木受害率下降58.54%。

| Abstract: | There are 17 species of scarab in Diebu forest nursey and they belong to 10 genera,2 families.Among them,the species with serious damages are Polyphylla gracilicornis with 1 generation for 4 years,Mimela holosericea with 1 generation for 1 year,Melolontha hippocastani mongolica with 1 generation for 6 years,etc.The single seedling type,long time seedling trandplanting,non-seedling rotation,non-land fallowing and using undecomposed organic manure were main causes led to occurrence of scarab damages.After trapping and killing with 250 W hydrargyrum light at nursery during the fastigium of imago eclosion,the annual pest density decreased 52.63% and the damage rate of seedling declined 58.54%. |
