The effect of metallic copper on development of Aedes albopictus was studie
d in the laboratory. Multiwire electric cable was used as a source of metal
lic copper in flower saucers colonized by Ae. albopictus. A linear regressi
on coefficient of 0.68 was obtained between copper concentration in the wat
er during larval development and the relative production of adults. Larval
mortality was higher in earlier instars with less evident effect on 4th-ins
tar larvae and pupae. The effect of copper on larval development time and a
dult weight in both sexes was also observed. The strong algicidal action is
presumed to only partially explain the effect of metallic copper on Ae. al
bopictus larvae. A direct toxic effect also may be involved. The use of met
allic copper is suggested as a practical alternative method for preventing
development of Ae. albopictus in small containers such as flower saucers fo
und in urban areas.
