Abstract

Abstract The gypsy moth is one of the most serious pests in forests and fruit tree plantations over prevailing parts of the Northern Hemisphere. This work is based on a literature review, and presents history of gypsy moth Lymantria dispar L., observed in Slovak forests within the period 1945–2020. The life cycle, hosts, natural enemies, population dynamics of pests, impact of outbreaks on forests and different management methods used in the past are discussed. Since 1945, there were nine gypsy moth outbreaks in Slovakia. Between 1945 and 2020, a total of 155,034 ha of deciduous forests were touched with varying intensity, representing an average annual damage of 2,040 ha. The strongest outbreak culminated in 2004. Totally 51,479 ha were attacked in the period of 2000–2008. We have found outbreak periods that repeat with frequency of 7.8 ±2.2 years and the average outbreak phase lasts 3.1 ±1.1 years. The period between two subsequent outbreaks seems to be more or less constant and duration of the outbreak phase seems to be gradually shortened during the study period. Several factors influencing the gypsy moth population dynamics in Slovakia are discussed. The role of biological control by using entomopathogenic fungus Entomophaga maimaiga is described.

1945-2020年斯洛伐克共和国舞毒蛾(Lymantria dispar L.)的发生及其爆发

舞毒蛾是北半球主要地区森林和果树种植园中最严重的害虫之一。这项工作是基于文献综述，并介绍了舞毒蛾Lymantria dispar L.的历史，在1945年至2020年期间在斯洛伐克森林中观察到。讨论了害虫的生命周期、寄主、天敌、种群动态、虫害爆发对森林的影响以及过去使用的不同管理方法。自1945年以来，斯洛伐克爆发了9次舞毒蛾疫情。1945年至2020年期间，共有155,034公顷的落叶森林受到不同程度的破坏，平均每年损失2,040公顷。最严重的疫情在2004年达到顶峰。2000年至2008年期间，共有51,479公顷的森林遭到袭击。我们发现爆发周期的重复频率为7.8±2.2年，平均爆发阶段持续3.1±1.1年。在研究期间，随后两次爆发之间的时间似乎或多或少是恒定的，爆发阶段的持续时间似乎逐渐缩短。讨论了影响斯洛伐克舞毒蛾种群动态的几个因素。介绍了昆虫病原真菌虫食菌(Entomophaga maimaiga)的生物防治作用。
