Egg collection traps have been studied to assist in the integrated control of arbovirus vectors. Many enhancements have been made over the years.
This study evaluated the use of a hydrated superabsorbent polymer (SAP) in the egg collection of Aedes aegypti and Aedes albopictus in ovitraps. An experiment was conducted in the laboratory to determine the minimum concentration of the product to be used in traps in the field to prevent the development of larvae into adults. In the field, the use of polymers has been evaluated using a traditional model of ovitraps. The positive ovitrap index and mean number of eggs per trap indicator were calculated.
In the laboratory, the larvae did not successfully develop to the adult stage, even at the lowest SAP concentration. In the field, the results showed that ovitraps with SAP proved to be effective for egg collection from both species. It was possible to identify sites with the highest concentration of species and expose the ovitraps for a longer period without larval development.
There is a need for studies on the adequacy of this technology for control programs. However, the results showed that ovitraps with hydrogel were potentiated to capture eggs, configuring themselves as another tool for vector control.
卵收集陷阱已被研究用于协助虫媒病毒病媒介的综合控制。多年来，已经进行了许多改进。
本研究评估了在诱卵器中使用水合高吸水性聚合物 (SAP) 收集埃及伊蚊和白纹伊蚊的卵。在实验室中进行了一项实验，以确定在田间使用陷阱时要使用的产品的最低浓度，以防止幼虫发育成成虫。在野外，使用聚合物已使用传统的诱卵器模型进行了评估。计算了阳性诱卵器指数和每个诱卵器的平均卵数指标。
在实验室中，即使在 SAP 的最低浓度下，幼虫也未能成功发育成成虫。在野外，结果表明 SAP 诱卵器可有效收集两种物种的卵。可以识别物种浓度最高的地点，并延长诱卵器的暴露时间而不会导致幼虫发育。
需要对该技术在控制计划中的充分性进行研究。然而，结果表明，水凝胶诱卵器增强了对卵的捕获能力，将其自身配置为另一种控制媒介的工具。
