摘　　要：于2008年3月柚子花期,将柚园划分为两个区域,一个区域引迁黄蚁,另一个区域不做处理作为对照。在2个区域分别选取20个枝条共40枝,对柚子花期主要害虫(柑桔花蕾蛆、蓟马)及健叶率进行调查。结果表明:对照区柑桔花蕾蛆和蓟马的虫口密度及虫花率都显著高于处理区,而且虫口数量一直保持在较高的水平;有黄蚁存在的情况下,柚子树花蕾蛆的有虫花率减少了70%～80%,蓟马有虫花率减少了近60%,健叶率增加了30%左右。建议在今后害虫综合防治中,充分认识到黄蚁对害虫的防治作用,通过保护和引迁黄蚁来有效防治害虫。In March 2008,the flowering stage of grapefruit,the plantation was divided into two sections,one section was introduced with Oecophylla smaragdina,and the other was used as the control. 20 branches were selected from each section to investigate the main pests （Contarinia citrt and Thrips spp.） of grapefruit and the percentage of undamaged leaves. In control section,the individual numbers of the two pest species maintained at a higher level,and their population density and the damaged rate of grapefruit flowers were significantly higher than those in the O. smaragdina-introduced section （P〈0.05）. The existence of O. smaragdina decreased the C. citrt-damaged rate of grapefruit flowers by 70%-80% and the Thrips spp.-damaged rate of grapefruit flowers by approximately 60%,and increased the percentage of undamaged leaves by 30%. It was suggested that in the pest control of grapefruit plantation,the roles of O. smaragdina should be fully considered,and its protection and introduction should be strengthened.
