摘　　要：为了解永兴岛岛礁植物虫害发生动态,系统开展了8种危险性害虫在永兴岛的种群消长动态与发生规律调查研究。首次发现木瓜秀粉蚧、扶桑绵粉蚧、椰心叶甲、美洲斑潜蝇、拟三色星灯蛾、透翅天蛾、蔷薇三节叶蜂、榕蓟马在永兴岛的季节消长动态存在显著差异。木瓜秀粉蚧和扶桑绵粉蚧种群数量表现为从春季到夏季显著增加后显著下降至秋季,然后又从秋季显著增加到冬季到最大值;椰心叶甲、美洲斑潜蝇、榕蓟马种群数量表现为从春季显著下降到秋季,然后又从秋季显著增加直至次年春季达到最大值;拟三色星灯蛾、透翅天蛾、蔷薇三节叶蜂种群数量表现为从春季显著增加到夏季达到最大值后又显著下降至冬季最小值。在永兴岛,木瓜秀粉蚧和扶桑绵粉蚧均存在5月小发生高峰期和11月大发生高峰期共2个发生高峰期,椰心叶甲、榕蓟马、美洲斑潜蝇均在3月有1个发生高峰期,拟三色星灯蛾、透翅天蛾、蔷薇三节叶蜂均在5月有1个发生高峰期。上述结果表明,木瓜秀粉蚧和扶桑绵粉蚧在5月和11月,椰心叶甲、榕蓟马和美洲斑潜蝇在3月,拟三色星灯蛾、透翅天蛾、蔷薇三节叶蜂在5月突发成灾概率较大。To understand the occurrence and dynamics of plant pests in Yongxing island,the population dynamics and occurrence regularity of eight dangerous pests in Yongxing island were systematically investigated.It was found for the first time that the seasonal dynamics of Paracoccus marginatus,Phenacoccus solenopsis,Brontispa longissima,Liriomyza sativae,Utetheisa lotrix,Cephonodes sp.,Arge geei,and Gynaikothrips ficorum were significantly different on Yongxing island.The populations of P.marginatus and P.solenopsis rose from spring to summer,decreased to autumn,and then increased from autumn to the maximum in winter,all significantly.The populations of B.longissima,L.sativae,and G.ficorum decreased from spring to autumn,then increased from autumn to the largest in the coming spring,both significantly.The populations of U.lotrix,Cephonodes sp.,and A.geei increased from the spring to the maximum in summer and then decreased to the mini-mum in winter,both significantly.On Yongxing island,there was a small occurrence peak in May and a large occurrence peak in November for P.marginatus and P.solenopsis,one occurrence peak in March for B.longissima,L.sativae and G.ficorum,and one occurrence peak in May for U.lotrix,Cephonodes sp.and A.geei.The results above indicated that there might be a higher probability of sudden disaster of P.marginatus and P.solenopsis in May and November,B.longissima,L.sativae,and G.ficorum in March,U.lotrix,Cephonodes sp.and A.geei in May.
