ABSTRACT
Mesocyclops aspericornis abounds in village ponds. Hence, the predatory capacity of M. aspericorniswas considered for use as a biological control agent for Aedes aegypti mosquitoes. In laboratoryexperiments, M. aspericornis consumed 33–50 mosquitoe larvae within 24-hours time period. M.aspericornis preyed upon only the first instar larvae of Ae. aegypti within a few seconds after theirintroduction. It started feeding on the tail portion first and ended with the head capsule. The meanvalue (triplicate) showed that the predatory capacity was 45.76 against the control 1.2. M. aspericornisprefers only the first instar mosquitoe larvae and feeds on them voraciously. When the Aedes larvaeattained the second instar stage, M. aspericornis attacked and killed them.
