| Popis: | Polyphagous thrips, like western flower thrips Frankliniella occidentalis and onion thrips Thrips tabaci, are major pests in various ornamental and vegetable crops in greenhouses throughout the world. In Hungary, both of these polyphagous thrips species frequently cause severe damage in many greenhouse crops, especially in commercial sweet pepper. Chemical control is not always feasible because of certain ecological characteristics of these thrips species. The commercially available phytoseiid predatory mites like Amblyseius swirskii and anthocorid flower bugs like Orius laevigatus are often used simultaneously for the biological control of severe thrips infestation in sweet pepper cultivation in Hungary. Our observations demonstrated that the polyphagous thrips assemblages were effectively controlled by the combined release of natural enemies, despite the fact that the establishment of O. laevigatus did not seem to be successful in the first year. Overall, the thrips population density remained below the economic threshold in both years. However, the low infestation level of thrips suggests that a single predator release strategy could be applied effectively and still maintain the thrips below the damage threshold in greenhouse sweet pepper. |
