在室外纱笼中，用重力Cx进行一选择和二选择试验。对致倦库蚊的诱蚊效果进行评价和改进。随后，在现场试验中，将改进的Box型重力阱与其他三种重力阱（CDC重力阱、CFC重力阱和新型粘性重力阱）进行了比较。Box重力诱捕器的主要缺点是诱捕效率相对较低，但通过对诱捕器结构的简单修改克服了这一缺点。用蚊帐代替收集盘的实心盖，使捕蚊器入口的空气流速提高了一倍，改善了捕获雌蚊的休息场所质量。结果，改进后的Box重力捕集器捕获并保留了两倍的Cx。在筛选笼中进行两种选择生物测定，并证明与市售的CDC重力诱捕器一样有效，但不会损坏所收集的标本。Box和CDC重力阱的捕获量明显大于逆流几何重力阱或粘性重力阱的捕获量。
In outdoor screen cages, one and two-choice assays were conducted with gravid Cx. quinquefasciatus to assess and improve the efficacy of the Box gravid trap. Subsequently, in a field trial, a modified Box gravid trap was compared with three other gravid traps: the CDC gravid trap, the CFC gravid trap, and a novel design of a sticky gravid trap. A major disadvantage of the Box gravid trap, a relatively low trapping efficacy, was overcome with a simple modification to the trap configuration. By replacing the solid lid of the collecting tray with mosquito netting, the air velocity through the trap inlet was doubled and the quality of the resting sites for caught females was improved. As a result, the modified Box gravid trap caught and retained twice as many Cx. quinquefasciatus as its predecessor in two-choice bioassays in the screened cages and proved as effective as the commercially available CDC gravid trap in the field, but without damaging the collected specimens. Captures with the Box and CDC gravid traps were significantly greater than those of either the Counter Flow Geometry gravid trap or a sticky gravid trap.
