在大规模饲养按蚊时，通常每天将蛹与幼虫分开，以防止不必要的成虫从托盘中出现。根据设备和物种的不同，最常用于分离的 2 个物理特性是：浮力密度和尺寸。在本报告中，我们描述了一种基于两个阶段之间浮力密度和行为的自然差异连续分离阿拉伯按蚊幼虫和蛹的系统。我们确定 4-15 摄氏度的温度既不会导致死亡，也不会降低化蛹或羽化的可能性。随着温度降至 4 摄氏度，分离效果得到改善。我们设计并演示了 15 摄氏度的水涡流分离器，预计每小时可处理约 100 万只幼虫和蛹
In mass rearing of anopheline mosquitoes, pupae are usually separated from larvae on a daily basis to prevent unwanted adult emergence from trays. Depending on the device and species, 2 physical characteristics have most often been used for separation: buoyant density and size. In this report, we describe a system for continuous separation of Anopheles arabiensis larvae from pupae based on the natural difference in buoyant density and behavior between the 2 stages. We determined that temperatures 4-15 degrees C caused neither mortality nor reduction in likelihood of pupation or emergence. Separation improved as temperatures decreased down to 4 degrees C. We devised and demonstrated a 15 degrees C water vortex separator that we anticipate can process approximately 1 million larvae and pupae per hour with
