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 <i>Mesocyclops annulatus</i> on <i>Aedes aegypti</i> and <i>Culex pipiens</i> larvae. A single adult female of <i>M. annulatus</i> caused 51.6% and 52.3% mortality of 50 first inst...

description In laboratory bioassays we tested the predatory capacity of the copepod <i>Mesocyclops annulatus</i> on <i>Aedes aegypti</i> and <i>Culex pipiens</i> larvae. A single adult female of <i>M. annulatus</i> caused 51.6% and 52.3% mortality of 50 first instar larvae of <i>Ae. aegypti</i> and <i>Cx. pipiens</i> respectively, in a 72 h test period. When alternative food was added to the containers, mortality rates declined to 16% and 10.3% for <i>Ae. aegypti</i> and <i>Cx. pipiens</i> respectively. When 50 first instar larvae of each of the two mosquito species tested were placed together with a single adult female of <i>M. annulatus</i>, mortality rates were 75.5% for Ae. aegypti larvae and 23.5% for Cx. pipiens larvae in a three day test period. Different density of adult females of <i>M. annulatus</i> ranged from 5 to 25 females produced mortality rates of <i>Ae. aegypti</i> first instar larvae from 50% to 100% respectively. When a single adult female of <i>M. annulatus</i> was exposed to an increasing number of first-instar <i>Ae. aegypti</i> larvae ranging from 10 to 100, 100% mortality was recorded from 1 to 25 larvae, then mortality declined to 30% with 100 larvae. The average larvae killed per 24 h period by a single copepod were 29.
