Synergists action of piperonyl butoxide and S,S,S-tributyl phosphorotrithioateontoxicity of carbamate insecticides against Blattella germanica

Conclusions In most of these strains, resistance to bendiocarb and carbaryl is completely eliminated by DEF, showing a very high role of estraze enzymes in resistance to bendiocarb and carbaryl. 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.
