研究结果在国内首次明确,稻赤斑黑沫蝉若虫只有在老熟临羽化之前,才由杂草根际爬至杂草地上部分泌沫形成泡沫团,故其应定名为羽化泡沫团。田间不同时刻羽化泡沫团的消长,本质上从属于老熟若虫出土量的变化。老熟若虫出土爬至杂草上的高峰期出现在19时30分钟左右。羽化集中在夜间,峰期在午夜前后。据此研究结果,提出采用系统调查泡沫团消长,以监测该虫动态变化的新方法。 The results for the first time in China were clear. The rice cicada nymphs of Nymphoides nirvana only grow in the mature part of the weeds until they emerge from the rhizosphere. Therefore, they should be named as eclosion foam nodules. The emergence and decline of feathering foam groups at different times in the field are essentially subordinate to the changes in the amount of unearthed mature nymphs. Ripening nymphs climb to weeds on the peak appeared at about 19:30. Feather concentrated at night, peak around midnight. Based on these results, a new method of systematically investigating the growth and decline of foam aggregates to monitor the dynamics of the insects was proposed.
