| Resumo: |
The oviposition preference of Bemisia tabaci biotype B (Homoptera: Aleyrodidae) for bean (Phaseolus vulgaris L.) genotypes containing arcelin in the seeds was evaluated. The tests were carried out under greenhouse conditions, in the dry and wet seasons, with the following genotypes: ARC 3s, ARC 5s (wild genotypes containing arcelin in the seeds); ARC 1, ARC 2, ARC 3, ARC 4 (near isogenic lines containing arcelin in the seeds - EMBRAPA) and Porrillo 70, Bolinha, IAPAR MD 808 (commercial genotypes without arcelin). In the free choice and no-choice oviposition tests, Bolinha and Porrillo 70 genotypes were preferred for oviposition by that insect. The Bolinha susceptibility could be related to the great number of acicular trichomes presents on its leaves surface. The wild genotypes, ARC 5s and ARC 3s, showed oviposition nonpreference resistance type. This resistance is not related to the arcelin variants, since the bred genotypes also contain arcelin in its seeds and did not show resistance to B. tabaci, biotype B.
