Laboratory evaluation of Mesocyclops annulatus (Wierzejski, 1892) (Copepoda: Cyclopidea) as a predator of container-breeding mosquitoes in Argentina

In laboratory bioassays we tested the predatory capacity of the copepod Mesocyclops annulatus on Carafe Aedes aegypti and Culex pipiens larvae.A single adult female of M.annulatus caused 51.6% and 52.3% mortality of 50 first instar larvae of Ae.aegypti and Cx.pipiens respectively, in a 72 h test period.When alternative food was added to the contain
