I used five arenas with three, ten, twenty, thirty, and fifty nymphs each, and I put two pairs of parasitoids in each arena. Every 24 hours, the new nymph was replaced in each arena. I had completed five replications.
My sugest. First of all. Concepts must be defined. Functional parasitism rate = Efficiency of a biological medium when applied by the Herdenson and Tildon Adjusted Efficacy formula.
An adjusted effectiveness is achieved and a greater approximation is achieved to the true effectiveness of a biological control agent on a certain species, which links control treatments with those of the application of the biological product.
