摘　　要：芒果壮铗普瘿蚊(Procontarinia robustaL i,Bu&Zhang)是新发现的危害厦门市园林绿化主要树种芒果的一种新害虫。该虫主要危害叶片,在芒果叶面上隆起形成虫瘿,严重影响城市园林绿化景观。在厦门芒果主要种植在城市主干道、公园、小区、机关单位和学校等地方,该树种树形高大,喷雾法用药量大,操作困难且对空气造成污染。选用几种具有内吸、上下输导作用的药剂(10%吡虫啉可湿性粉剂、16%虫线清、蚧诛净等)在树干基部打孔注药,发现芽前注药明显优于芽后注药。处理后虫口减退率都在90%以上,能较好地控制芒果壮铗普瘿蚊的虫口密度。Procontarinia robusta Li, Bu ＆ Zhang, a new species found just recently, is a pest attacking mango trees. Mango, a main species of urban garden greening in Xiamen, is planted along the main streets, parks, residencies, campus, etc. P. robusta makes galls on mango leaves, which endangers urban green landscape. It is difficult to control this pest by spraying insecticide, due to the huge tree canopy. So trunk injections of three systemic insecticides： imidacloprid WP, 16% chongxianqing EC, 25% omethoate EC, were tested to control the population of P. robusta. The result showed that before the budding period of trees, the injection treatments could reduce pest population to a low lever-below 10 percent.
