Abstract

91 words

Tomato crop in the central Sudan is liable to heavy infestation by the leaf miners, Liriomyza spp. Field experiments indicated significant differences in varietal susceptibility of varieties and tomato breeding lines to Liriomyza spp. The breeding line Trop G 9–18 and the varieties, Alfa, Peto 86 and Strain B were the least infested (resistant). Laboratory tests revealed that Flora Dade was more susceptible to L. sativae than Trop-G, whereas the latter was resistant to L. trifolii. Resistance is attributed to anti-feedants and also associated with the glandular trichomes on the leaves.
