| Abstract:
The experiment on effectiveness of 3 predatory mite species (Phytoseiulus persimilis, Neoseiulus fallacis, Typhlodromus pyri) and their mixture, in controlling Tetranychus urticae on black currant plantation, was conducted in south part of Poland. The predators were introduced only once in first year of experiment. During 2 years the plantation was inhabited by other native species of Phytoseiids (mainly Euseiulus finlandicus) which almost entirely displaced the introduced predatory mites. The native predators kept T.urticae population on very low level during whole season. | |
