球蚧象(Anthribus kuwanai Yuasa)属鞘翅目长角象科,是大绛蚧(Kermes vastus Ku-wana)的重要天敌。在国外此虫分布于日本,国内分布于河南、江苏等省大绛蚧发生区。据我们在南京市、江宁县、镇江市及连云港市调查,凡有大绛蚧发生的地方,均有球蚧象,其林间捕食大绛蚧的猎食率29—67%,常能显著地控制大绛蚧的危害。此虫国内尚未见报道。为探索球蚧象的利用价值及途径,我们自1985年起对其生物学特性进行了观察。
Anthribus kuwanai Yuasa belongs to the family Coleoptera, an important natural enemy of the Kermes vastus Ku-wana. In the foreign distribution of this worm in Japan, located in Henan, Jiangsu and other provinces large crimson occurrence area. According to our survey in Nanjing, Jiangning, Zhenjiang and Lianyungang, where there is a large scale, all have scale dinosaurs. The predation rate of large-scale scales in forests is 29-67%, which can often be significant To control the harm of large crimson scales. This insect has not been reported in the country. In order to explore the value and ways of using Diabatic phenomena, we have observed its biological characteristics since 1985.
