Population fluctuations of Ceratitis capitata (Wiedemann) were evaluated over a period of 12 mo in four altitudinal strata (400-750, 750-1,100, 1,100-1,450, and 1,450-1,800 meters above sea level, masl) in Eastern Guatemala. Within each altitudinal range, sampling plots were established in coffee plantations and adjacent areas, in which Jackson traps were set and baited with Trimedlure. Coffee berries and other host fruits were collected. Population density was lowest at the 400-750 masl stratum and highest at 1,450-1,800 masl. At every altitudinal range, the fluctuations of the pest were associated mainly with the availability of ripe coffee berries as a primary host. From 750-1,450 masl, the pest was also associated with the availability of sweet orange and mandarins in commercial and backyard orchards. The highest densities of the pest were recorded in the dry season. Citrus were the main alternate host where ripe coffee berries were not available. This knowledge on population dynamics of C. capitata will contribute to develop more effective area-wide pest management strategies including the use of sterile insects, natural enemies, and bait sprays.
在危地马拉东部，对海拔400 - 750米、750 - 1100米、1100 - 1450米和1450 - 1800米的四个海拔层次，进行了为期12个月的地中海实蝇（Ceratitis capitata (Wiedemann)）种群波动评估。在每个海拔范围内，在咖啡种植园和相邻区域设置采样区，在其中放置杰克逊诱捕器并用甲基丁香酚诱捕。采集咖啡浆果和其他寄主果实。种群密度在海拔400 - 750米层次最低，在1450 - 1800米层次最高。在每个海拔范围内，害虫的波动主要与作为主要寄主的成熟咖啡浆果的可获得性有关。在海拔750 - 1450米之间，害虫还与商业果园和后院果园中甜橙和柑橘的可获得性有关。害虫的最高密度出现在旱季。柑橘是成熟咖啡浆果不可用时的主要替代寄主。关于地中海实蝇种群动态的这一知识将有助于制定更有效的区域害虫管理策略，包括使用不育昆虫、天敌和诱饵喷雾。
