Control Measure

Synopsis

  • In 1974 Aedes aegypti with chromosomal translocations engineered in the laboratory were mass produced and released in Chibarani village in coastal Kenya.
  • Insects with rearranged but otherwise complete genomes (translocations) can be perfectly viable
  • However, most of their progeny will die because of the absence of parts of the genome and/or over abundance of others (deletions, aneuploidy)
  • Introduced sterility into the Chibarani population was extensive.
  • This study emonstrated the effectiveness of introducing translocations into a field population of A. aegypti to suppress populations.

Sterility introduced by release of genetically altered males to a domestic population of Aedes aegypti at the Kenya coast

P. T. McDonald, W. Hausermann and N. Lorimer,  Am J Trop Med Hyg,  26:553-61. 1977.
The release of males heterozygous for one or two sex-linked translocations was effective in introducing a high level of sterility into a domestic population of Aedes aegypti at a Rabai village. The effect of the releases continued for several weeks after the release period. Male ...
