DIAS DE ALMEIDA, Gustavo; PRATISSOLI, Dirceu; MATHIAS HOLTZ, Anderson  e  VICENTINI, Victor Bernardo. BIOFERTILIZER AS INDUCTOR OF RESISTANCE TO THE COLONIZATION OF AGAINST THE WHITEFLY IN THE BEAN PLANT. Idesia [online]. 2008, vol.26, n.1, pp.29-32. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292008000100004.

The potential for resistant Bemisia tabaci populations to develop as a consequence of intensive use of chemical insecticides has stimulated studies on integrated pest management tactics, for example, the induction of host-plant resistance.The objective of this work was to evaluate the effect of the biofertilizer in the resistance induction in bean to the whitefly. Tests were accomplished with free-choice and no-choice tests of oviposition preference of the insect in cultivating of carioca bean. The design was completely randomized, with four treatments, being accomplished a general application in the soil, except for witness. After the first definitive pair’s of leaves appearance the applications were road leaf, being the treatments in the following way: 1, witness, 2) just an application in the soil, 3) an application in the soil one more application to foliate, 4) an application in the soil more two applications foliate. The biofertilizer caused negative effect in the population of the whitefly for the reduction of the oviposition. In that way, that product can be efficient in the handling of the whitefly in bean plantings.
