ABSTRACT
Quadraspidiotus perniciosus on apple trees, in the prefecture of Florina, Greece. Half of the experimental area was used as a check field (no application) and in the rest a chemical insecticide was used. Sticky and pheromone traps of the same type were used for monitoring Q. perniciosus in both fields. Samples were taken every 10 days and pheromone application was renewed every month until 17 of October for year 2004 and 22 of October for year 2005. Sticky traps were used for monitoring insects of immature stages. For controlling Q. perniciosus two applications were made using insecticide chlorpyrifos (Dursban) in the application field, at 19 of June and 19 of July for year 2004 and 14 of June and 14 of July for year 2005. Results showed that, populations of adult insects and of immature stages of Q. perniciosus were considerably increased in the check field during the two years of this study. In the application field insect populations were considerably decreased due to the effectiveness of the insecticide used applied. Year conditions influenced statistically significantly population fluctuations of insects (in adult and immature stages). There was not found any relation between trapped male population and larvae population and this was considered the most important finding for monitoring purposes.]]>
