| Abstract: | During an experiment carried out in 2009–2010 we observed different population densities of Typhlodromus pyri in three monitored pear cultivars in Organic Pest Management (OPM) as well as Integrated Pest Management (IPM) orchards.
In both years the population density of T. pyri was the highest in the cultivar Conference (organic orchard). The lowest population density was found in 2009 on the cultivar
Dicolor (IPM orchard) and in 2010 on the cultivar Bohemica. Factors involved are discussed. |
