The first strategy used Integrated Pest Management (IPM) through mass trapping, release of Nesidiocoris tenuis and rational use of compatible insecticides. The second strategy was based on conventional use of synthetic insecticides (9 treatments). This study revealed at the end of the culture a 20% infestation rate of leaves in the IPM cropping system versus 98% in the conventional cropping system. The infestation rate of fruit was 18.2% in the IPM cropping system versus 46.8% with the conventional one. 收起
