广西旱地作物主要金龟子种类及其发生动态初步调查

摘要

2011－2013年，通过挖土调查和太阳能诱虫灯系统调查了广西各地旱地作物金龟子的种类及其种群动态。统计结果表明，全区共采集到金龟子4个科56种，发生盛期为4月底至7月上旬；各地发生种类和时期不同，主要优势种为深绿异丽金龟、红脚异丽金龟、异丽金龟和桐黑异丽金龟，发生盛期分别为5月下旬至7月中旬、6月中旬至8月上旬、5月中旬至6月中旬、5月中旬至6月下旬。%Species of scarabs and population dynamics of dominant species which damaged the upland crops were investigated by soil-scraping and light traps in Guangxi from 2011-2013. Fifty-six species of scarabs belonged to 4 families in Scarabaeoidea were collected,the emergence peak was from late April to early July. Species of scarabs and their emergence period were different between the regions. The dominant species of scarabs in Guangxi were Anomala heydeni,A. cupripes,Anomala sp. and A. antiqua,and the emergence peak was from late May to mid-July,mid-June to early August,mid-May to mid-June,mid-May to late June,respectively.
