简介：这研究被瞄准调查PhyllocnistiscitrellaStainton的出现(柠檬leafminer；CLM)，它最近在南部的南朝鲜，和它的天赋引起了增加的损坏到柠檬农场敌人，它能充当生物控制代理人。在现在的学习，用性pheromone陷井监视的CLM在南朝鲜在Jeju区域在主要柠檬农场被进行。另外，寄生虫的调查被执行为CLM检测有效控制代理人。在从2011～2015的调查期间，成年CLM(2,386,990)的一个相对大的数字在性pheromone陷井被观察。CLM的吝啬的年度出现是477,398，它随温度的增加显示出一个增加的趋势。寄生虫的调查在2015年11月被进行。六个寄生虫被发现，它，Quadrastichussp。并且Sympiesissp。显示出寄生状态的最高的率。寄生状态的吝啬的率在调查时期期间是3.97?%。我们在南朝鲜发现了CLM的寄生虫的四新种。
