Abstract: A study on the Zeuzera coffeae Nietner was made in Jiangsu province from 1977 to 1978. There is one generation a year. The larvae are borers which infest the twig of trees, including locust, hickory, apple and other, and overwinter in the tunnel of deied twigs. The adult emerges from middle May to early July the next year and lay its eggs in the tunnel of dried twigs. New hatched larvae are thrown about by wind and bore holes at the edge of buds. Infested shoots wither quickly and will readily be broken by wind. The male moth is active at night and may be attracted by light. Natural enemies of the larvae amount to more than five species, namely, Bracon sp., ant, Fusarium moniliformes, virus and birds. Several insecticides, such as Omethoate, Sumithion, Imidan etc. were used to spray or brush on the trunk to control the larvae, but results showed that these insecticides had little or no effect. Silvicultural measures, including cutting off and clearing away the injured twigs should be recommended for the control of this pest. Natural enemies should also beprotected and utilized.
