Based on 168,674 records in the database ChryFaun changes in distribution and abundance of leaf beetles (Chrysomelidae s.l.) in Central Europe were analysed from 1900 through 2009. From the first decade (1900-1909) to the last (2000-2009) the number of records per decade increased by factor 26, from 1513 to 41,269. The number of species increased from 395 in decade 1 to 606 in decade 10, but only 532 were reported in decade 11. The number of species with fewer records increased from 1990 although the total number of records increased continuously. Decrease and increase is found likewise in mono-, oligo-, and polyphagous species. Twenty-two species (3.0%) have not been reported since 1990, and 42 (5.8%) since 2000. 71% of all taxa reported between 2000 and 2009 had fewer records than in the immediately previous decade. These indications of decline correspond with numerous published studies on decline in other groups of arthropods. Analysis shows that data from private and public collections are useful for the retrospective analysis of numbers and distributions of leaf beetles (and other organisms).
基于数据库ChryFaun中的168,674条记录，分析了1900年至2009年中欧叶甲（广义叶甲科）分布和丰度的变化。从第一个十年（1900 - 1909年）到最后一个十年（2000 - 2009年），每十年的记录数量增加了26倍，从1513条增至41,269条。物种数量从第一个十年的395种增加到第十个十年的606种，但在第十一个十年仅报告了532种。记录较少的物种数量自1990年以来有所增加，尽管记录总数持续上升。单食性、寡食性和多食性物种中同样发现了减少和增加的情况。自1990年以来，有22种（3.0%）未再被记录，自2000年以来有42种（5.8%）未再被记录。2000年至2009年期间报告的所有分类单元中，71%的记录数量少于上一个十年。这些减少迹象与众多已发表的关于其他节肢动物类群减少的研究结果相符。分析表明，来自私人和公共收藏的数据对于回顾性分析叶甲（及其他生物）的数量和分布很有用。
