Abstract
Abstract
Five copepod species, Acantocyclops robustus, Macrocyclops albidus,
Mesocyclops annulatus, Thermocyclops sp. (all Cyclopoidea) and
Argyrodiaptomus bergi (Calanoidea), were evaluated under laboratory
conditions as potential predators of preparasites of the mermithid nematode
Strelkovimermis spiculatus. Adults of all five copepod species consumed
70-100% of the preparasites within 24 h. Copepodids and adults of M.
annulatus predated upon 93 and 100% of the nematode pre-parasites,
respectively. An average of 197 pre-parasites was daily predated upon by an
adult M. annulatus. Copepod density affected prevalence and intensity of S.
spiculatus on mosquito larvae. Prevalence and intensity of S. spiculatus on
Aedes aegypti larvae was reduced from 98% and 2.8 nematodes per larva in
control containers free of copepods to 61.4% and 1.4 nematodes per larva in
containers with 50 M. annulatus females per l.
