Abstract: In the present paper the resistance of the housefly to tetramethrin, cypermethrin, permethrin and deltamethrin is reported. Despite the fact that in Hungary synergized pyrethrins and pyrethroids have rarely been used, some populations exhibited moderate resistance to all the agents tested. In the case of tetramethrin, the resistance index calculated from the LD50 values was higher than 100, higher than 10, between 5 and 10, between 1 and 5, and below 1 for 2, 1, 2, 7 and 3 housefly populations, respectively (a total of 15 populations were monitored). The lowest resistance was found to cypermethrin: in two housefly populations it was more than 5-fold, in 6 populations between 1- and 5-fold, whereas 7 populations were less susceptible than the WHO/SRS strain used for comparison. Of the 17 housefly populations monitored for permethrin resistance 2, 3 and 6 had more than 10-fold, 5-10-fold and 1-5-fold resistance, respectively, whereas 6 populations proved to be more susceptible than the WHO/SRS reference strain. One, 2, 4 and 6 of the 13 housefly populations tested for deltamethrin resistance exhibited a resistance index higher than 20, between 10 and 20, between 5 and 10, and between 1 and 5, respectively.
