Acaricides pyrimidifen

Recently introduced insecticide/acaricides, pyrimidifen and fenaza-quin (Figure 3.13), also inhibit the mitochondrial electron transport chain by binding with complex I at coenzyme site Q.

Pyrimidinamine insecticides contain a pyrimidine and an amine group. Pyrimidifen is an insecticide/acaricide for control of spider and rust mites in apples, pears, vegetables, tea, and citrus. Its oral LD in rats is 148 mg/kg.

Flufenerim (S-1560 Table 28.3.1) is an acaricide/insecticide under development [21] that appears to be a more recent derivative of pyrimidifen, but possessing less labile substitutions on the head and tail regions (Fig. 28.3.2). Available information suggests that flufenerim has acaricidal activity and perhaps some lepidop-teran and fungicidal activity as well [21, 63, 64].
