Abstract

The objective of this work was to verify the influence of the management of irrigated rice stubble, during soil tillage, on the reduction of  pre‑hibernating populations of the rice stem bug (Tibraca limbativentris). The treatments consisted of the following rice stubble managements: one harrow pass; two harrow passes; two harrow passes, with a leveling pass; and a control. In each sampling unit, the number of nymphs and adults of the rice stem bug was determined. In the soil preparation, at least two harrow passes are necessary to reduce the pre‑hibernating population of the rice stem bug.
