These traps presented the measures of 25cm of length for 9,5 cm of width and glue in the two faces, that serve to capture the arthropods. A trap was placed 1,5m of the ground in the interior of the central plant of each parcel, totalizing 24 traps in the experiment. The traps had been kept in the field per 15 days and later they had been substituted by new, without interruption, during all the experimental period. With the captured insects it was elaborated a entomolgica collection for identification and register. For analysis ends statistics, the numbers of nymphs of psildeos for leaf had been submitted to test F, for analysis of variance, and to the test of Tukey, for comparison of the averages. The percentages of reduction of the plagues had been calculated by the formula of Abbott (1925).

For the attainment of the statistical correlations, the gotten data had been submitted to the analysis of simple linear correlation. RESULTS AND QUARREL infestation of the psildeo met at the beginning below of 30% of new leves attacked in all the treatments of the harvest. Exactly thus, the agriculturist carried through a spraying with the insecticide dimethoate, in the dose of 40,0 g.i.a. /100L of water, in 13/02/2004, aiming at the preventive control of T. limbata.

All the parcels of the different treatments (strategies) had also presented accented rise of the numbers of nymphs of T. limbata and of the attacked leaf percentages, in the period of 27/12/2004 the 04/03/2004, surpassing 30% of infestation. This population increase determined the first application, that was carried through in the day o8/03/2004. This intervention was adapted of Jacomino et al (2002), that they had established the level of action of 30% of the infested plants (MIP). The exception was in the conventional treatment, where the agriculturist carried through application, in day 04/03/2004, with the methamidophos insecticides, in the dose of 30,0 g.i.
