【 摘 要 】

A wide variety of arthropodpests that cause damage in agricultural crops can be found worldwide. The tomato leafminer (Meyrick) (Lepidoptera: Gelechiidae) is considered to be one of the most significantpests which affects greenhouse tomato crops. The tomato leafminer causes direct damage when larvae produce galleries in leaves, shoots and calix of immature fruits throughout their feeding process, which affects the photosynthesis and makes the fruit unattractive resulting in serious economic loss. This research was carried out to investigate the efficacy of a variety of handmade mass trapping equipped with solar-powered Light Emitting Diodes (LEDs) and combined with pheromones, as an alternative biological control, in order to capture tomato leafminers adults in greenhouse tomato crops in Concordia, Argentina. Different types of traps were tested, namely, traps supplemented with LEDs 430, 470 nm with or without sex pheromones, which were compared to a witness trap of sex pheromone. The study was designed as a randomized complete block design replicated 2 times (greenhouses). These traps were placed at random and along the cor-ridor at an even distance among one another changed on a two-weekly basis in order to eliminate bias from the capture results. These results showed that the total average number of tomato leafminer adults caught in the trap equipped with LEDs 470 nm in combination with sex pheromone was higher compared to the other traps.
