Popis: The predatory mite Neoseiulus cucumeris is an efficient beneficial against thrips. This study aims to develop a preventive control method against the thrips Frankliniella occidentalis in integrated production of roses in greenhouse. At the same time, the assumption of obtaining a better efficiency by increasing the frequency of releases and by decreasing the amount in every release was to check. Three treatments were carried out in this trial in compartments: a control treatment, without releases (1), introductions of N. cucumeris every 4 weeks with the amount of 1 sachet per m2 (2) and introductions every week with the amount of 1/4 sachet per m2 (3). The study showed that for the same number of N. cucumeris released, a better efficiency is obtained with more frequent releases and reduced amounts in every release.
