Bicyclo-[2,2,1]-heptanes, bicyclo-[2,2,2]-octanes and bi- cyclo-[2,2,3]-nonanes having 2 or 3 ring hetero atoms selected from 0, S and N, substituted at the 1-position by a 4-alkynylphenyl group and at the 4-position and optionally at the 3 and/or 5-position are valuable pesticides, particularly insecticides and acaracides. The compounds may be prepared by reacting an alkyne with the corresponding 4- iodophenyl substituted compound or by debromination of the corresponding 4-dibrom- omethylphenyl substituted compound.
