The tomato leafminer, Tuta absoluta (Meyrick) is one of the major threats to tomato production. Larvae can cause losses of more than 80% of production. Therefore, studies were carried out first to update current geographical distribution of the pest through the country then to find out methods combining anti-insect nets and biopesticides to protect tomato crop against this new threat. Pheromone traps were placed on tomato production sites in 16 locations of the country. At the research station, the experiment was laid out in a lattice 4×4 design with 4 replications and 4 treatments: control (without protection), biopesticide control, anti-insect net with smaller holes (63 mesh cm -2) + biopesticides, and insect net with larger holes (40 mesh cm -2) + biopesticides. Oxymatrin extract (Levo 2.4 SL) at a dose of 1 L ha -1 week, neem oil (1%) and Bacillus thuringiensis 'Kurstaki' (29 g 15 L of water week-1) were applied in association with insect nets. Results showed that the leafminer pest was found in all visited locations. Tomato leafminer is well established in all tomato production areas causing damages on tomato. The combination of anti-insect net + biopesticides showed the best tomato crop protection against the leafminer T. absoluta.
