摘要
首次在南昌应用高空测报灯对蝼蛄全年田间发生种群动态进行诱集监测。通过逐日统计灯下蝼蛄诱捕成虫结果表明:南昌地区灯下诱捕到的蝼蛄100%全部为东方蝼蛄。2014年5月15日至12月1日,期间共计诱捕东方蝼蛄4 967头,全年灯下未见华北蝼蛄。东方蝼蛄成虫在全年内有多个高峰时期,灯下成虫高峰时期主要分布在6月上旬、6月底至7月上旬和7月下旬,8月5日后至监测结束,成虫零星发生。
For the first time in Nanchang, a vertical pointing searchlight trap was used to monitor the adult population dynamics of Gryllotalpa in fields throughout the year of 2014. Based on the daily statistics of adult catches by the vertical pointing searchlight trap, results showed that Gryllotalpa orientalis made up 100%of the adult Gryllotalpa population. During May 15 to December 1, 2014, the total number of adults collected was 4 967, and no Gryllotalpa unispina was found. There were at least 3 emergence peaks during the monitoring period, such as in early June, during the end of June to early July, and in late July, but adults sporadically occurred after August 5 until the end of the monitoring in December.
