摘要

The Asian chestnut gall wasp (ACGW), Dryocosmus kuriphilus , native to China was accidentally introduced into many countries worldwide, including Italy. Different susceptibilities have been reported in literature among cultivated plants belonging to different gene pools worldwide, but this aspect has not been sufficiently explored among wild chestnut populations. The aims of this multiyear study were (i) to assess differences in susceptibility to ACGW in wild C. sativa plants coming from different parts of Europe grown in an experimental plot in Central Italy, (ii) to preliminarily analyse the relationships between temperature, relative humidity and rain variables of winter and summer and D. kuriphilus infestation. Provenances coming from Greece reported a significantly smaller number of galls than the Italian and Spanish ones in the three-years of survey, showing a lower susceptibility to ACGW attacks in respect of plants coming from Italy and Spain. Interannual variation of ACGW infestation in the chestnut provenances may be influenced by the local environmental conditions. A hot and dry summer, occurred in 2015, could be responsible for a marked decrease in ACGW population density during 2016. The results lead to suppose that the different genotypes considered have different reactions depending on environmental conditions and ACGW attacks.

Sativa植物的差异。（ii）预先分析温度之间的关系，相对冬季和夏季的湿度和雨变量和D. Kuriphilus侵扰。来自希腊的杂粮报告了比意大利和西班牙语在三年的调查中的含量明显较少，对来自意大利和西班牙的植物来说，对ACGW袭击的敏感性较低。栗子杂交中ACGW侵染的续变量可能受到当地环境条件的影响。 2015年发生了一个炎热和干燥的夏天，2016年可能负责ACGW人口密度的显着降低。结果导致认为考虑不同的基因型根据环境条件和ACGW攻击而具有不同的反应。
