Abstract:The adults Apriona germari (Hope) were separately fed on shoot bark of paper-mulberry and Populus deltoides cv. "Lux" Ⅰ-69/55. The results of feeding showed that the average longevity of female adults fed on shoot bark of paper-mulbety was 74. 2 days longer than that fed on shoot bark of poplar, and the average longevity of male adult fed on shoot bark of papermulberry was 58.8 days longer than that fed on shoot bark of poplar. The female adults fed on shoot bark of poplar could not lay eggs. Planting paper-mulberry in poplar plantation to attract and kill adults of Apriona germari (Hope) and clearing away paper-mulberry. And mulberry tress within 500m around poplar plantation were proved to be effective. The percentage of trees infected by larvae in poplar plantation with planted paper-mulberry as attractive trees was lower than that of control plantation by 61. 6% after two years. The percentage of trees infected by larvae in poplar plantation cleared from mulberry and paper-mulberry was lower than that of control plantation by 42. 3%-77% in the year of question.
