  1. Descriptive analysis (E) = Reduction in parasitism (A) or emergence (B) in percent and their respective IOBC toxicity classes (I). Parasitization and emergence rates were estimated for the females of A.arizonensis (of respective field populations) exposed to lethal doses (LC50) of imidacloprid, profenofos and thiodicarb.
  2. E(A) = Per cent reduction in parasitization (%); E(B) denotes percent reduction in emergence (%) I refers to IOBC Toxicity classes: 1 = harmless, 2 = slightly harmful, 3 = moderately harmful, 4 = harmful.
