Abstract
Hemos probado la toxicidad del aceite del eucalipto limón (OLE)
contra las larvas de mosquito tigre Aedes (Stegomya) albopictus
(Skuse, 1895) (Diptera: Culicidae) y contra vertebrados acuáticos
no objetivo, el pez Gambusia affinis (Baird and Girard, 1853) y el
renacuajo de la rana Pelophylax perezi (López-Seodane, 1885). La
mezcla acuosa de OLE fue efectiva como larvicida y letal para
gambúsias y renacuajos. La mezcla acuosa expuesta durante una
semana al aire libre no tuvo efectos sobre las larvas. El OLE puro
aplicado sobre la superficie del agua matólas larvas a muy bajas
concentraciones y sin tener en cuenta el volumen del agua. El OLE
ha mostrado ser un compuesto útil contra las larvas de mosquito tigre
especialmente en los lugares de cría aislados de los ecosistemas
nativos.
ABSTRACT: We evaluated the toxicity of oil of lemon eucalyptus (OLE) against larvae of the tiger mosquito Aedes (Stegomya) albopictus (Skuse, 1895) (Diptera: Culicidae) and non-target aquatic vertebrates, the fish Gambusia affinis (Baird and Girard, 1853) and the tapole of the frog Pelophylax perezi (López-Seodane, 1885). The water-mixture of OLE was effective as a larvicide and lethal to both mosquitofish and tadpoles in the short-term. The water-mixture left in the open air over a week had no effect on larvae. Pure OLE released on the water surface killed larvae at very low concentrations irrespectively of the volume of water medium. OLE seems a useful compound to be used against tiger mosquito larvae especially in mosquito breeding sites isolated from native ecosystems.
