Abstract
New phenoxy-phenyl ethers, their manufacture and use for the control of insects and representatives of the order acarina are disclosed. The compounds correspond to the formula ##STR1## wherein W represents --O--, --S--, R.sub.1 represents C.sub.1 --C.sub.6 -alkyl, C.sub.3 --C.sub.6 -cycloalkyl or C.sub.5 --C.sub.6 -cycloalkenyl, C.sub.2 --C.sub.4 -haloalkenyl, C.sub.3 --C.sub.5 -alkynyl, C.sub.2 --C.sub.4 -alkenyl or benzyl, R.sub.2 represents hydrogen, methyl or ethyl, R.sub.3 represents hydrogen or methyl, or R.sub.2 and R.sub.3 together with the chain represent a 5- or 6-membered saturated ring, and R.sub.4 and R.sub.5 each represent hydrogen or methyl.
