Predatory capacity and prey selectivity of nymphs of the dragonfly Pantala hymenaea (Odonata: Libellulidae) were evaluated on larvae of the mosquito Culex quinquefasciatus (Diptera: Culicidae) and larvae of the midge Chironomus plumosus (Diptera: Chironomidae) as prey. With functional response methodology, 7 larval densities were exposed to predator individuals in a glass jar under laboratory conditions. The study was performed in 2 experiments. The 1st was a test system with each prey species alone. The 2nd tested a mixture of both prey species in a 1:1 ratio. Prey selectivity and prey capacity were significantly greater on midge larvae than on mosquito larvae.
以致倦库蚊（双翅目：蚊科）幼虫和羽摇蚊（双翅目：摇蚊科）幼虫作为猎物，评估了蜻蜓黄蜻（蜻蜓目：蜻科）若虫的捕食能力和猎物选择性。采用功能反应方法，在实验室条件下，将7种幼虫密度暴露于玻璃罐中的捕食者个体。该研究分2个实验进行。第一个是每个猎物物种单独的测试系统。第二个测试了两种猎物物种1:1比例的混合物。对摇蚊幼虫的猎物选择性和捕食能力明显高于对库蚊幼虫的。
