Abstract
Tuta absoluta – tomato leafminer (Meyrick) (Lepidoptera: Gelechiidae) is a major pest of tomato crops in protected areas, which attacks both foliage and fruit, in all phases of plant growth. Its invasion has led to yield and quality decrease, increased costs to control and high dependence on chemical insecticides. With pheromone traps it is possible to monitor and reduce the density of the pest population. The experience was established in 2020, at a farmer in Dobreni village (Giurgiu county). In the first and second crop cycle, the population of the pest Tuta absoluta was monitored, by placing Delta pheromone traps in tomato crops. The Sahmat F1 tomato hybrid was planted in both crop cycles. Pest monitoring was performed weekly, by changing the adhesive plates with pheromones from Delta traps, on the dates: 03.06, 10.06, 17.06, 24.06, 01.07, 08.07, 15.07, 22.07 in the first cycle of crop and on the dates: 29.07, 05.08, 12.08, 19.08, 02.09 , 09.09, 16.09, 23.09 in the second cycle. The appearance and evolution of the attack were recorded in the both crop cycles and its influence on production was established.
