Pheromone traps and other methods in assessing pine beauty moth (Panolis flammea Schiff.)

The objective of this research was to evaluate different methodologies for quantifying pine beauty moth (Panolis flammea Schiff.) populations in pine stands of Southern part of Lithuania. Evaluations were conducted in selected pine stands by assessing the following: pupae (in the litter); larvae (falling from trees after chemical knock down); and adult insects (using pheromone traps). Analysis of evaluation methods indicated that the populations can be assessed most accurately by using the counts of larvae. This method is used when outbreaks occur or aerial spraying of insecticides is needed. Assessment of pupae in the litter is the most suitable method for silvicultural purposes; the use of pheromone traps is less precise than the other two methods.
