Biological control of Thrips palmi
In Japan experiments were carried out to estimate the suppressive effect of Orius sp. on Thrips palmi (EPPO A1 pest) on aubergine under field conditions.
It was investigated that the thrips density and the damage on aubergine fruits due to thrips was considerably lower when the predator was present.
