Abstract :
[en] The tomato leafminer, Tuta absoluta (Lepidoptera: Gelechiidae), is a devastating
pest that develops principally on solanaceous plants throughout South and Central America
and Europe. In this study, we tested the influence of three levels of T. absoluta infestations
on the attraction and oviposition preference of adult T. absoluta. Three infestation levels
(i.e., non-infested plants, plants infested with 10 T. absoluta larvae, and plants infested with
20 T. absoluta larvae) were presented by pairs in a flying tunnel to groups of T. absoluta
adults. We found no differences in terms of adult attraction for either level of infestations.
However, female oviposition choice is influenced by larvae density on tomato plants.
We discuss the underlying mechanisms and propose recommendations for further research
