Abstract
The objective of this experiments was evaluate the control of Bemisia tabaci and Thrips tabaci, through the use of plant oils associated or not to insecticide in bean plants, besides verifying the consequences on yield. The experiment was carried out in the period of rainy seasons, by utilizing Carioca variety. The statistical design was the randomized blocks, by employing a 6x2 factorial scheme (plant oil versus insecticide), totalizing 12 treatments and four replications. It was concluded thet application of plant oils without insecticide can be utilized on the control of the B. tabaci biótipo B, since their population and the symptoms of golden mosaic was similar to the treatment plant oils plus insecticide; among the plant oils Agrex® plant oil promoted a higher control of white fly. For T. tabaci the application of plant oil associated to insecticide provide with a smaller population index when compared to the treatments without this association. The yield was not affected by the population of B. tabaci biótipo B and T. tabaci when plant oils were utilized, associated or not to the insecticide.
