Analysis on the effect of an invasive pest, Dryocosmus kuriphilus and its introduced parasitoid on the native host and parasitoid fauna

在半个多世纪前引进这种害虫的日本和最近发现这种害虫的意大利，同时评估了由入侵害虫库里菲斯引起的长期和短期影响。在日本，从中国大陆引进的天敌中华小蜂已成功地控制了库里菲斯小蜂，但首次明确分析了其对近缘关系密切的本地寄生蜂的直接影响。这些结果将使意大利的库里菲斯生物防治试验在短时间内取得成功。

Both long and short term impacts induced by an invasive pest, Dryocosmus kuriphilus, were simultaneously assessed in Japan where the pest was introduced more than half century ago and in Italy where the pest was found very recently. In Japan, D.kuriphilus has been successfully controlled by its natural enemy, Torymus sinensis, introduced from mainland of China, however, its direct effects on the closely related native parasitoids were clearly analyzed for the first time. Those results would lead a trial for the biological control of D.kuriphilus in Italy to its success in a short time.
