Abstract

The acaricidal properties of some new halogen‐substituted heterocyclic‐aromatic sulphides and sulphones are described. As a rule, the adulticidal activity is negligible, though some compounds show interesting ovicidal properties. The sulphides possess a higher ovicidal activity than the sulphones. The pyridyl sulphides are the most active, the thiazolyl sulphides somewhat less, whereas the pyrimidyl and thienyl sulphides are almost inactive. The pyridine‐N‐oxides are also inactive. The polarity of the compounds synthesized seems to exert a considerable influence on the ovicidal properties.
