Study on the Correlation of Chemical Structure and Ovicidal Activities of 2-Bromoethylthiobenzenes

2-Bromoethylthiobenzenes were toxic to the eggs of Tetranychus telarius (L.) depending on the permeability and the reactivity of the compounds. It was suggested by the means of ρ-σ-π analysis that the reactivity depends on the electron-donating power of the sulfur atom to the site of action or the carbon atom of carbon-bromine linkage.
