中文摘要:
      为了明确灯诱和引诱剂对田间金龟害虫的诱捕效果,利用自动虫情测报灯和2种引诱剂诱捕器对同一块花生田发生的金龟甲的诱集效果进行了对比试验。结果表明,两种方式对金龟甲的诱集效果差异明显。诱虫灯对东北大黑鳃金龟Holotrichia diomphalia和铜绿丽金龟Anomala corpulenta的日均诱虫量分别为3.30头和1.27头,引诱剂诱捕器对两种金龟甲的日均诱虫量分别为1.25头和0.34头。自动虫情测报灯的诱虫总量和持效性较好,均明显优于引诱剂诱捕器的诱捕效果。引诱剂诱捕器对雌性东北大黑鳃金龟的特异诱集效果优于自动虫情测报灯。尽管两种诱捕方式全年诱虫量存在较大差异,但两者所监测得到的金龟甲发生动态趋势基本一致,且特殊气象条件诱集数据可相互补充,并提出大面积防治工作中应以虫情测报灯为主,引诱剂诱捕器可作为重要辅助手段。
英文摘要:
      In order to test the attractive effect against the scarabs, we applied an automatic pest forecast light trap and two kinds of attractant trap to attract the scarabs from a same peanut field in a comparative experiment. The result showed that there were rather distinct differences on the attractive effect between two methods above. The average daily trapped quantities of Holotrichia diomphalia and Anomala corpulenta by the lamp were 3.30 and 1.27 heads, 1.25 and 0.34 heads were trapped by attractant traps in one year, respectively. The automatic pest forecast light trap was better than attractant traps both in the total trapped quantity and its persistence. We also found that the attractant traps were much specific in attracting the female H. diomphalia than the automatic pest forecast light trap. Although the two methods had disparities in quantity in one year, the occurrence dynamics of two dominant scarabs gathered by two different methods were basically the same. The data obtained under special meteorological conditions could be as a mutual supplement for the two different methods. We proposed that light traps should be as an optimal choice in the pest prevention and control in fields of a large scale, attractant traps could be used as an important auxiliary tool.
