Members of the Anopheles gambiae complex breed in clean, sunlit temporary bodies of water. Anthropogenic pollution is, however, altering the breeding sites of the vectors with numerous biological effects. Although the effects of larval metal pollution have previously been examined, this study aims to assess the transgenerational effects of larval metal pollution on the major malaria vector An. arabiensis.
In Eurasia, studies of fluctuations in the borders of areas occupied by sibling species of this complex, as well as their relative proportions in the areas where they are sympatric are epidemiologically important.
It was concluded that there was an overall lethal effect of N. oleander extracts against mosquito, An. stephensi larvae which could be manipulated to develop a safe and effective larvicide.
The present study investigated the genetic structure of An. sinensis populations using a 729 bp fragment of mtDNA ND5 among 10 populations collected from seven provinces in China.
These observations suggest some interesting growth-disrupting constituents in the plants, with possible application in the practical control of mosquito larvae in aquatic ecosystems.
Each data set analyzed separately yielded a different topology but none provided evidence for the separation of An. halophylus and An. triannulatus C, consistent with the hypothesis that the two are undergoing incipient speciation.
