Effect of heavy metals on Aedes aegypti (Diptera: Culicidae) larvae
Studies were conducted to determine the biological effects of heavy metals on the development of Aedes aegypti. Embryos immersed in 32 ppm Cu or 5 ppm Cd did not hatch. The arrest of hatching was in part reversible by removal of the heavy metals. The mortality rate of third-instar larvae exposed to...

| description | Studies were conducted to determine the biological effects of heavy metals on the development of Aedes aegypti. Embryos immersed in 32 ppm Cu or 5 ppm Cd did not hatch. The arrest of hatching was in part reversible by removal of the heavy metals. The mortality rate of third-instar larvae exposed to heavy metals for 24 h was metal and dose dependent; the 50% lethal concentration (LC50) endpoints were 3.1, 16.5, and 33 ppm for Hg, Cd, and Cu, respectively. Interestingly, a proportion of Aedes aegypti third-instar larvae exposed to either Cu or Cd for 24 h failed to produce a dissectable peritrophic matrix. This failure to produce a dissectable peritrophic matrix also was metal and dose dependent. These results are discussed in the context of Aedes aegypti as a model system for investigating the molecular biological effects of heavy metals in aquatic insects. |
