The big bud mite is a resurgent pest of hazelnut, , causing substantial yields reductions in many productive areas. Mites colonise and develop within healthy buds which become swollen, with subsequent alteration to the plant's development. To date, there has been limited knowledge on how the cultivar and pest management strategies affect infestations. This study explored these aspects through two ad hoc experiments carried out in central Italy. In the first experiment, the susceptibility of 11 cultivars with different geographic origins was tested in a germplasm hazelnut collection. The second experiment assessed the infestation level in orchards with integrated pest management (IPM) and organic pest management strategies and in a renaturalised environment (a former agricultural area now converted in a natural park). The results showed that the most and the least susceptible cultivars were Tonda Gentile and Nocchione, respectively. No significant differences were found between IPM and organic management, but they were both different to the renaturalised environment. The outcomes of this research can serve as a valuable reference and can be applied to all current or potential hazelnut cultivation areas characterised by the same environmental conditions.
大芽螨是榛子的一种再度肆虐的害虫，在许多产区导致产量大幅下降。螨虫在健康的芽内繁殖并发育，芽会肿胀，随后植株的发育也会改变。迄今为止，关于品种和害虫管理策略如何影响虫害的了解有限。本研究通过在意大利中部进行的两项专门实验探索了这些方面。在第一个实验中，在一个种质榛子收集中测试了11个不同地理来源品种的易感性。第二个实验评估了采用综合虫害管理（IPM）和有机虫害管理策略的果园以及在一个自然恢复环境（一个从前的农业区现已转变为自然公园）中的虫害水平。结果表明，最易感和最不易感的品种分别是“圆叶榛”和“诺基奥内”。在IPM和有机管理之间未发现显著差异，但它们与自然恢复环境均不同。本研究的结果可作为有价值的参考，并可应用于所有具有相同环境条件的当前或潜在榛子种植区。
