Abstract
Susceptibility of seven tomato hybrids (both leaves and fruits) to infestation by the tomato borer Tuta absolutalarvae were examined under field conditions throughout 2018/2019 and 2019/2020 seasons. Further, the feeding preference of T. absolutalarvae to both leaves and fruits of the seven tomato hybrids were tested under laboratory conditions. The results showed that both leaves and fruits of tomato hybrids differed in their susceptibility or resistance degree to infestation by T. absolutalarvae. Tomato leaves of hybrids 65010, 83 and 039 were susceptible to larval infestation by T. absoluta in both seasons of the study, whereas tomato fruits of hybrids 65010, Super red and 039 were susceptible to larval infestation in both seasons. The feeding preference of T. absoluta larvae after 1 and 24 hours to both leaves and fruits of the seven tested tomato hybrids differed significantly either after 1 or 24 hours under laboratory conditions. After one hour, larvae exhibited the highest preference to leaves of hybrid 83, hybrid 102 and hybrid Lugen, whereas after 24 hours, hybrid 102 and hybrid 039 attracted the highest and lowest percentages of larvae. On fruits, the larvae of T. absoluta showed the highest preference after one hour to hybrid Super red and the lowest to hybrids 65010, 102, Lugen, 449 and 039.  After 24 hours, the highest and the lowest percentages of attracted larvae to fruits were recorded on hybrid 039 and hybrid 65010, respectively.
