The seasonal occurrence and diel landing periodicity of Sabethes chloropterus (Humboldt) was studied weekly for 1 yr using the human bait catch in the Pt. Gourde Forest, Trinidad, W.I. Population abundance remained low throughout the dry season (16%) but increased after the onset of the rains in May and peaked by the middle of the rainy season (July-October). The diurnal periodicity of landing was unimodal during the wet season with a major peak between 1200-1600 hours and bimodal during the dry season with peaks at 0800-1000 and 1200-1400 hours. This study documents for the first time the periodicity of landing by Sa. chloropterus at ground level and suggests reasons for failure to detect the yellow fever virus at this level.
在西印度群岛特立尼达岛的古尔德角森林，采用人饵诱捕法，对绿翅萨贝蚊（洪堡）的季节性出现情况和昼夜着陆节律进行了为期1年的每周监测。在整个旱季，种群数量一直较低（16%），但在5月降雨开始后增加，并在雨季中期（7 - 10月）达到峰值。在雨季，着陆的昼夜节律为单峰型，主要峰值出现在12:00 - 16:00时；在旱季为双峰型，峰值出现在08:00 - 10:00和12:00 - 14:00时。本研究首次记录了绿翅萨贝蚊在地面的着陆节律，并提出了在此层面未能检测到黄热病病毒的原因。
