The resistance of 11 tomato cultivars (Ps-6515, Berlina, Poolad, Petoprid-5,
Zaman,Matin, Golsar, Sandokan-F1, Golshan-616, Sadeen-95 and Sadeen-21)
to the tomato moth, Tuta absoluta (Meyrick) (Lepidoptera:Gelechiidae) was
investigated under field conditions. A randomized complete block designwas
used with three replications. Data analysis indicated that there were significant
differences (P<0.05) among cultivars regarding leaflet damage, leaf
damage, overall plant damage, number of mines per leaf, number of holes
on the stem, and fruit. Our findings revealed that the cultivars Berlina,
Golsar, Poolad, and Zaman were less suitable cultivars, suggesting that they
are more resistant to the tomato moth than the other cultivars. The high
density of leaf trichomes present in the cultivars Berlina, Zaman, and Golsar
can be one of the possible causes of resistance to T. absoluta. Knowledge of
the extent of susceptibility or resistance of cultivars to a pest on a crop is one
of the fundamental components of integrated pest management (IPM) programs
for any crop.
