摘 要:桑天牛喜以构树、桑树为补充营养的原因及其应用的初步研究高瑞桐(中国林业科学研究院林业研究所北京100091)刘传银,卢永农,徐邦新,邓儒继(山东省沂南县林业局沂南276360)(湖北省嘉鱼县林业局嘉鱼437200)关键词桑天牛,补充营养,构树,桑树,...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.
