Sources of resistance to Scrobipalpula absoluta (Meyrick, 1917) in tomato

Eighty-five wild and cultivated tomato accessions, being 71 Lycopersicon esculentum, 10 L. pimpinellifolium and 4 L. peruvianum, were evaluated in greenhouse, under artificial infestation, for resistance to Scrobipalpula absoluta (Meyr.) (Lepidoptera: Gelechiidae). NAV 29 and NAV 115 (L. peruvianum) showed the least foliar damage while NAV 98 (L. pimpinellifolium) was less attacked in the buds than cultivated tomatoes (L. esculentum). Then, a comparative trial was carried out among the Rio Grande and Pacesetter tomato cultivars, NAV 98 and NAV 29/115 (mixed offsprings of NAV 29 and NAV 115, because of self-incompatibility). The highest level of resistance to the pest was presented by NAV 29/115.
