The diel pattern of oviposition of wild-caught Anopheles albitarsis derived from rice fields in Frederick Settlement, Trinidad, was studied in the laboratory by recording the performance of egg-laying individuals and a colony at 2-h intervals. Oviposition was almost exclusively nocturnal, with 79.3% of the eggs being laid during the scotophase. During the rest of the day and during evening twilight, 7.8 and 12.9% eggs were laid, respectively. Wild-caught parous females allowed to engorge on human blood matured, on average, 71.1 +/- 12.4 follicles (range 53-106). These findings provide vector control personnel with the opportunity to maximize the impact of insecticides on An. albitarsis populations by restricting their operations to the time of peak activity.
通过每隔2小时记录野生捕获的来自特立尼达弗雷德里克定居点稻田的白跗按蚊的产卵表现，在实验室中研究了其昼夜产卵模式。产卵几乎完全在夜间进行，79.3%的卵在暗期产下。在一天中的其余时间和傍晚黄昏时，分别产下7.8%和12.9%的卵。让野生捕获的经产雌蚊吸食人血后，平均有71.1±12.4个卵泡成熟（范围为53 - 106个）。这些发现为病媒控制人员提供了机会，通过将其操作限制在活动高峰期来最大限度地提高杀虫剂对白跗按蚊种群的影响。
