Simazine, a triazine herbicide, was tested for its genotoxic potential
in the Drosophila wing spot and sex-linked recessive lethal tests fol
lowing larval exposures. 3rd and 2nd instar mwh +/+ flr(3) transhetero
zygous larvae were given chronic exposure to various concentrations of
the test compound to record the frequency of wing spots in the eclosi
ng adult wings. The standard Base technique was followed for the sex-l
inked recessive lethal test, where Oregon-R larvae of similar age were
exposed to the compound. It is concluded that simazine is genotoxic b
oth in the wing primordial and male germ line cells of Drosophila.
