Treatment Evaluation
Explained
 		Nt and nt are average moth counts in pheromone traps in year t in the treatment block and in the control area around it, respectively. Treatment is done in year t. In the case of mating disruption or intensive trapping, evaluation is performed in year t +1. Thus, Nt and nt in equations for T and C are replaced by Nt+1 and nt+1. If values of nt-1 or nt are less than 0.05, then they are replaced by the value of 0.05 for estimating of T. Treatment is successful if T > 0.67; partially successful if 0.33 < T < 0.67; and unsuccessful if T < 0.33. If C is much >1, then the colony is still present and may require additional treatments.

PPA = Potential Problem Area, detected by the Decision Algorithm from previous year data.
Treatment agents: Btk (or Bt, BT) = Bacillus thuringiensis var. kurstaki;
MD (or PF) = Mating disruption with pheromone flakes containing disparlure;
NPV = virus, preparation Gypchek;
DIM = Dimilin (=diflubenzuron);
Trap = Mass trapping;
