Abstract

DUQUE L., Jonny E.; MUNOZ L., Anibal  and  NAVARRO-SILVA, Mario A.. A simulation model for the control of the Aedes aegypti, the mosquito vector of dengue and yellow fever, by the crustacean Mesocyclops spp.. Rev. salud pública [online]. 2004, vol.6, n.1, pp.87-99. ISSN 0124-0064.

OBJETIVE: A simulation model is presented to show the predation dynamics of Mesocyclops spp. over Aedes aegypti.i METHODS: The system is represented through four differential equations. H'(t), quantity of eggs; L'(t), quantity of larvae; A'(t), quantity of adults and C'(t), quantity of copepods. Initially the equations are of the classic predator-prey type, according to Lotka (1924) and Volterra (1926). Then it is modified into a system with functional response for invertebrates, according to Holling. RESULTS: The first system effectively controls and stabilizes the mosquito population, while the second suggests that copepods may be ineffective as mosquito controllers. CONCLUSIONS: The need to study predator-prey systems (copepodos-mosquitos) with projects that integrate laboratory and of field tests is recognized. Only then will it be possible to establish the validity of predators as effective biological controllers of mosquitoes.
