AbstractThe feeding preferences of Holotrichia cheni Chang adults with regard to fresh leaves of olive, Chinese chestnut and red bayberry were tested experimentally. A significant preference for olive leaves over those of the other two plant species, and for Chinese chestnut leaves over those of red bayberry, was apparent(P<001). The amount of feces excreted after feeding for 12 h on olive, Chinese chestnut and red bayberry leaves was(2030±1048)mg,(1006±766)mg and(80±96)mg, respectively. Furthermore, males produced approximately twice as much feces as females. The results indicate that olives are the primary host of H. cheni.
