1. A composition comprising a mixture of synergistically effective amounts of
(1) a compound of the formula (Ia)
in which W is H, X is CH 3 , Y is 5-CH 3 , Z is H, R is OCH 3 , and G is CO 2 —C 2 H 5 , and
(2) at least one compound selected from the group consisting of
(i) fenazaquin at a ratio of the compound of formula (Ia) to fenazaquin of from 5:1 to 1:5,
(ii) milbemectin at a ratio of the compound of formula (Ia) to milbemectin of from 10:1 to 1:1,
(iii) propargit at a ratio of the compound of formula (Ia) to propargit of from 5:1 to 1:5, and
(iv) pyridaben at a ratio of the compound of formula (Ia) to pyridaben of from 5:1 to 1:5.
2. A method for controlling insects and/or acarids comprising allowing an effective amount of a composition according to claim 1 to act on said insects and/or acarids and/or their habitat.
3. A process for preparing an insecticidal and acaricidal composition comprising mixing a composition according to claim 1 with extenders and/or surfactants.
