对阿根廷拉普拉塔的桡足类进行了调查，以了解当地蚊虫繁殖地幼虫的群落特征，并鉴定人工容器中发生的埃及伊蚊和淡色库蚊新的捕食性蚊种。在永久性水池中，环翅目幼虫的多样性最高。研究了粗壮棘环虫、乌鲁瓜氏双环鱼、白纹伊蚊和长中环藻的性别和年龄、对蚊种的选择性和5天内的日捕食率。雌性桡足类的捕食能力最强。没有发现蚊子对捕食性的偏好。根据总捕食势，桡足类排序如下：乌鲁瓜伊斯；粗壮；白垩纪；长脚。还评估了桡足类对干燥的耐受性和在人工容器中的水中生存的能力。在干燥条件下能存活，但在墓地花瓶水中存活率较低。白念珠菌不能在干燥条件下存活，也不耐受从人工容器中提取的水。经干燥或在花瓶水中繁殖后，最长分枝杆菌的存活率并未严重下降。新热带气旋类蚊虫Duruguaysis和A.robostus是很好的候选物种，值得进一步研究作为蚊虫的生防剂。
Copepods from La Plata, Argentina were investigated to characterize the local community of larvivorous copepods inhabiting mosquito breeding sites and to identify new predator species of the mosquitoes which occur in artificial containers, Aedes aegypti and Culex pipiens. Diversity of larvivorous cyclopoids was highest in permanent pools. Predation by sex and age, selectivity on mosquito species, and daily predation rate during five days were studied for Acanthocyclops robustus, Diacyclops uruguayensis, Macrocyclops albidus and Mesocyclops longisetus. Female copepods presented the highest predatory capacity. No predatory preference for mosquito species was found. According to overall predation potential, copepods were ranked as follows: D. uruguayensis < A. robustus < M. albidus < M. longisetus. Copepod tolerance to desiccation and capacity to survive in water from artificial containers were also evaluated. D. uruguayensis and A. robustus survived under dry conditions, but D. uruguayensis showed lower survival in water from cemetery flower vases. M. albidus did not survive under dry conditions and did not tolerate water extracted from artificial containers. M. longisetus survival was not severely reduced after desiccation or breeding in water from flower vases. The Neotropical cyclopoids D. uruguayensis and A. robustus can be considered good candidates and merit further research as biological control agents for mosquitoes.
