| 摘 要： | 为了探索柑橘小实蝇入侵扩散与危害规律,提高其监测与防控水平,2008—2010年应用柑橘小实蝇专用性诱剂和诱捕器,在全市19个镇(街道)35个柑橘园建立监测点进行全市性入侵扩散分布普查;在古城伏龙柑橘园和市区水果市场,建立2个系统监测点开展全年种群数量消长监测,结果表明柑橘小实蝇种群入侵扩散与时空分布呈塔型趋势,即以城区为中心,并呈向周边区域扩散蔓延趋势;全年种群时序数量变化主要呈单峰型曲线变化,一般于6月中下旬至7月上中旬初见性诱成虫,8月上旬形成增长拐点,9—10月形成数量高峰,影响种群数量消长的主要因子有种群基数、气候和生境条件等,从而创建柑橘小实蝇基数(m6)与全年种群诱量(M)关系模型M=23.8339m6+59.8003(n=6,r=0.9735**)、当旬虫口密度(mn)与其前3个月的旬平均气温(tn-9)关系模型mn=1.9248tn-9-14.88063(n=72,r=0.5123**),以及柑橘挂果期成虫诱量(M)、有虫株率(R%)、有虫果率(P%)、每虫果幼虫量(N)等关系模型:R=0.3667M-1.2746(n=11,r=0.8901**);P=0.0581R+0.3112(n=11...

| Abstract: | In order to explore the pattern of oriental fruit fly invasion,dissemination and damage,and improve monitoring and control techniques,the data on annual population dynamics were collected by applying specific sex pheromone traps in 35 monitoring points in the citrus orchard all over 19 communities of Linhai County and 2 systemic monitoring points in Fulong citrus orchard of Gucheng,and Linhai fruit market during 2008-2010.It was found that the temporal and spatial population distribution of oriental fruit f... |
