SUMMARY There was considerable potentiation between thanite and arprocarb in their actions on an insecticide‐susceptible strain of houseflies. The isobole at the LD 50 level was asymmetric, which was to be expected, since thanite probably potentiates arprocarb but not vice versa. The joint action ratio, i.e. the maximum actual potency of the jointly acting insecticides relative to what their joint potency would be if they showed additive action, was about 4·6 (apart from in one aberrant experiment). Thanite appears to potentiate arprocarb less than it potentiates isolan or m‐iso ‐propylphenyl N ‐methylcarbamate.
