Abstract

INTRODUCTION The whitefly (Bemisia tabaci Gennadius, 1889) B biotype is one of the most harmful pests that attack common bean crops, mainly for extracting large quantities of sap, excreting honeydew that causes sooty mould, and transmitting the bean golden mosaic vírus (BGMV) (Yuki et al., 1998). The disease is the largest constraint to bean production in Latin America and causes significant yield losses (40 to 100%) in South and Central America (Morales, 2006). In the hottest regions of Paraná State (Brazil), in the dry season (sowing from January to April), the BGMV incidence has reached 80 to 100% of plants, with production losses of 30% to 100% (Bianchini et al., 1989). The keeping insect populations below economic threshold levels can be reached with use of resistant cultivars, reducing the need of insecticides (Kavitha and Reddy, 2012). This is an important component of Integrated Pest Management and it is considered as non-monetary input at common bean farmers. This work aimed evaluate the resistance of common bean genotypes to B. tabaci B biotype.
