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的日本和最近才发现这种害虫的意大利，同时对一种名为kuriphilus的入侵害虫所造成的长期和短期影响进行了评估。在日本，已成功地利用从中国大陆引进的天敌中国稻蛾（Torymus sinensis）控制了kuriphilus，但首次明确分析了其对亲缘关系密切的本土寄生蜂的直接影响。这些结果将在短时间内为意大利的kuriphilus生物防治试验带来成功。

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.
