Gortyna xanthenes (Germar) and Depressaria erinaceella (Staudinger) are key pests of artichoke in Tunisia causing major losses. To this end, a 2-year field survey was carried out in order to assess possible damage caused by these two pests. The results showed that serious attacks were found on artichoke flower heads ranging from 17 to 26% and from 7 to 10% for D. erinaceella and G. xanthenes, respectively. On stems, damages caused by G. xanthenes may exceed 60%. Measures of the length of the larva and the width of head capsule in the laboratory showed the presence of six and seven instar larvae for G. xanthenes and D. erinaceella, respectively. These results could be very useful to develop effective management tools against artichoke pests in Tunisia.

在突尼斯调查了两种朝鲜蓟飞蛾“ Gortyna xanthenes(Germar)和Depressaria erinaceella(Staudinger)”

Gortyna xanthenes(Germar)和erpressaceer erinaceella(Staudinger)是突尼斯的朝鲜蓟的主要害虫,造成重大损失。为此,进行了为期两年的实地调查,以评估这两种有害生物可能造成的损害。结果表明,严重的袭击是对洋蓟花头17〜26%,7〜10%发现D. erinaceellaG.呫分别。在茎上,由G. xanthenes引起的损害可能超过60%。幼虫并在实验室头胶囊的宽度的长度的措施表明6的存在和七个龄幼虫为G.呫吨D. erinaceella, 分别。这些结果对于开发突尼斯针对朝鲜蓟害虫的有效管理工具可能非常有用。
