| خلاصه مقاله | Background: To determine the synergists action of piperonyl butoxide (pBO) and S,S,S-tributyl phosphorohithioate (DEF) on toxicity of carbamate insecticides against Blattella germainica in Tehran city.- Materials and methods: In the current sfudy, German cockroach strains wLre collected from sevlral hospitals and dormitories in Tehran .At the beginning, different concentrations of bendiocarb and carbaryl (insecticides belong to carbamate group) were determined by surface contact on a susceptible strain.Then, the level of susceptibility andtype of resistance mechanisms inthe collected strains from contaminated sites to the aforementioned insecticides were studied byusing PBO and DEF synergists with different insecticide ratios to synergist (1 :0, I : 1,1 :2,1:3). Results and discussion: The DEF synergist along with bendiocarb and carbaryl completely eliminated the resistance in all strains but PBO did not completely eliminate the resistance in tie strains of Mofid, Alvand, Valiasr hospitals and Shariati dormitory. Generally, the impact of DEF was observed in the iemoving resistance more than PBO. Conclusions: In most of these strains, resistance to bendiocarb and carbaryl is completely eliminated by DEF, showing a very high role of estraze enrymes in resistance to bendiocarb and iarbaryl. But in most strains PBO does not remove the resistance because other mechanisms, such as reduced cuticle penetration and insensitivity to the acetylcholine esterase enzyme, may be involved. |
