The tomato crop is attacked by several pests including Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae). In order to evaluate the effect of cultural practices in the management of tomato leafminer populations, a sampling of 75 tomato fields was carried out over four dry-season cropping cycles from 2015 to 2019. Cultural practices are recorded through a questionnaire from farmers. The results show that leafminer infestations are highest in the fields in 2015 and decrease in the following years. Lance and bucket watering, high plant density, previous crop (other than solanaceous), manure applications and hoe tillage decrease leafminer infestations in the fields. However, pesticides application, monocultures, the use of hybrid tomato cultivars and the short duration of nursery plants favour leafminer infestations. This study confirms the effect of cultural practices in the management of leafminer and basis for further consolidation of leafminer control strategies in Senegal.
