| Abstract: | Small scale glasshouse trials showed that second instar nymphs of Orius laevigatus reduced Frankliniella occidentalis numbers (78-92%) more than Neoseiulus cucumeris (0-30%). Combining the predators did not increase reduction of thrips numbers (84-93%). Pollen did not increase thrips control, but led to an increase in the number of thrips. |
