Trap to use for this pheromone:
Native to South America, this small moth (6–7 mm long and 10 mm wingspan), nocturnal, appeared in France in 2008 and is spreading at an exponential rate. Grey-brown in color, it has black spots on its wings. It is active all year round, spending its days hidden in the leaves and flying mainly in the morning and late in the day. Its mining larvae are responsible for the damage: mines and whitish spots on the leaves, which then turn brown and become necrotic, galleries in the fruits (green or ripe), galleries in the stems. It can cause up to 100% losses.
Egg-laying can take place on the underside of leaves, on stems, or on fruits. Hatching occurs 4 to 6 days later. The larvae then develop for 10 to 15 days by feeding on the crop. Cream-colored at first, they then become greenish to pinkish, and can measure up to 8 mm at the last stage. They then pupate for 10 to 12 days on leaves, in the mines, or even on the ground, then the moth emerges from its chrysalis. Males live 6 to 7 days and females 10 to 15 days. The duration of the different stages varies depending on temperature (a cycle can take 76 days at 14°C or 24 days at 27°C). Tuta absoluta can thus complete up to 12 generations per year.
