The effect of Dithane M-45 (dithiocarbamate fungicide; active substance: mancozeb) was studied on microarthropod fauna inhabiting dead wood. Although the exposure was almost never 100% lethal for the majority of observed taxa, almost all (Mesostigmata, Oribatida, some Uropodina, Actinedida, Collembola and Diplopoda) showed very high correlation between concentration of the fungicide and mortality (r > 0.86). Only Stigmaeidae showed low correlation (r = 0.293). For the majority of taxa LC(50 )values were close to the concentrations used during agrochemical activities in woods. Only Trachytes aegrota showed full susceptibility to the fungicide within the range of recommended field concentrations used in forestry (characterised by the low LC(95 )value). Tolerance of mesostigmatid and oribatid mites was found to differ between juveniles and adults, but not consistently. Related Uropodina species varied in susceptibility to the fungicide.
研究了代森锰锌（二硫代氨基甲酸盐类杀菌剂；活性成分：代森锰锌）对栖息在枯木中的微型节肢动物区系的影响。尽管对于大多数观察到的分类群而言，暴露几乎从未达到100%致死，但几乎所有分类群（中气门螨类、甲螨目、部分尾足螨亚目、前气门螨目、弹尾目和倍足纲）都显示出杀菌剂浓度与死亡率之间具有非常高的相关性（r>0.86）。只有长须螨科显示出较低的相关性（r = 0.293）。对于大多数分类群来说，半数致死浓度（LC50）值接近在森林中进行农药活动时所使用的浓度。只有黑胫突螨在林业推荐的田间浓度范围内对该杀菌剂表现出完全易感性（其特征是低95%致死浓度值）。发现中气门螨类和甲螨目的若虫和成虫对杀菌剂的耐受性存在差异，但并不一致。相关的尾足螨亚目物种对该杀菌剂的易感性各不相同。
