Leek moth pheromones

Leek and onion moth 🐛

The leek moth (Acrolepiopsis assectella) is a small pest moth whose caterpillars attack leeks, onions, and garlic. They burrow tunnels in the leaves and bulbs, which weakens the plant and encourages rot. Damage can be significant, especially at the end of summer.

Life cycle and egg-laying period 📅

After overwintering in plant debris, adults emerge as early as March/April. Females lay their eggs on the leaves or flower heads. In just 5 days, the larvae hatch, start by mining the leaves, then burrow into the heart of the vegetable.

The first generation often goes unnoticed, but the summer generations (July/August) are much more harmful and can devastate your crops if no protection is put in place.

Trap effectively with pheromones 🔍

Sex pheromones are volatile substances emitted by females to attract males. Each insect has its own pheromone, enabling targeted trapping that is environmentally friendly.
