Aspects concerning the monitoring of the pest Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) with pheromone traps on tomato crop under high plastic tunnels

Abstract

Tuta absoluta (tomato leafminer) is a pest that causes significant damage on tomato protected crops. The larvae attack both foliage and fruit during all tomato growth stages. The experience done at the R.I.V.F.G Vidra, in 2020, had as purpose the monitoring of this pest on tomato crop under high plastic tunnels using Delta trap with pheromones. Two traps were placed in 2 high plastic tunnels, one of which with insect proof net. The number of adults caught in the Delta traps was recorded weekly in the period May - August and varied between 14 and 583 (in the high plastic tunnel with insect-proof net) and between 9 and 708 (in the high plastic tunnel without net), respectively. The evolution of the pest attack on 3 different tomato hybrids was studied: Prekos F1, Beldine F1 and Siriana F1.
