大球蚧(Eulecanium excrescens Ferris)为苹果、梨、桃等果树的主要害虫,采用农药防治效果不理想,且污染环境,杀死果园大量天敌。蜡象Anthribus niveouariegatus(Roelofs)是大球蚧的重要天敌,其寄主除大球蚧外,尚有白蜡虫。1981年在南川解剖大球蚧400头,有301头被寄生,寄生率为75.3％。国内分布于白蜡虫分布区,四川—南川、峨眉、仪陇、广安、会理等县,国外日本。对蜡象的生物学特性进行了初步观察,结果整理如下。
Eulecanium excrescens Ferris is a major pest of fruit trees such as apple, pear and peach. Its pesticide is not effective in controlling diseases and it pollutes the environment and kills a large number of natural enemies in orchards. The waxy Anthribus niveouariegatus (Roelofs) is an important predator of large scale dinoflagellates. In 1981, Nanchuan anatomized 400 large scale insects, 301 were parasitic parasitic rate was 75.3%. Domestic distribution in the white wax insect distribution area, Sichuan - Nanchuan, Emei, Yilong, Guang’an, Huili County, foreign Japan. The biological characteristics of the wax as a preliminary observation, the results are as follows.
