Mating disruption for gGrapevine moth: complete guide

Mating disruption is a protection technique that uses synthetic pheromones to disorient male Lobesia botrana, preventing them from locating females. Without mating, the pest population drops sharply throughout the cycle. It is a sustainable strategy, with no impact on beneficial fauna, and significantly reduces the need for insecticide applications.

The technique is recommended for vineyards with a history of grapevine moth presence or in areas with moderate to high pest pressure. It works best when applied preventively, before the start of the first generation flight. It is particularly useful in integrated protection programs and in farms aiming to reduce chemical treatments. Early use improves long‑term vineyard sanitary stability.

The dispenser continuously releases specific pheromones that saturate the vineyard environment. This high concentration prevents males from detecting the natural scent of females, thereby reducing mating. The effect is long‑lasting and keeps pest levels low throughout the vegetative cycle. It is a key tool for stabilizing Lobesia botrana pressure.

Installation should take place before the flight of the first generation, ensuring that the pest is controlled from the beginning of the cycle. Early placement maximizes effectiveness and prevents protection gaps. It is advisable to follow regional phytosanitary bulletins to determine the ideal timing and ensure accurate intervention.

The density depends on the dispenser model and manufacturer recommendations, but it typically ranges between 300 and 500 units per hectare. Distribution must be homogeneous to ensure uniform coverage. In areas with higher pest pressure, additional reinforcement along vineyard borders may be required to maintain effective protection.

In many cases, it significantly reduces the number of treatments, but it does not entirely eliminate the need for intervention. In years of high pest pressure or when climatic conditions favour the pest, occasional complementary treatments may be required. The technique integrates easily into integrated protection programs and improves long‑term vineyard sanitary stability.

Mating disruption lowers pest population levels, reduces the risk of resistance, improves grape quality and decreases insecticide applications. It supports more sustainable production and helps preserve beneficial fauna. It is a safe, effective and widely validated solution in modern vineyard protection programs.

Yes, it can be applied in small vineyards (best efficacy in areas > 3 ha) or large ones, provided homogeneous coverage is ensured. It is especially recommended for certified farms or those transitioning to more sustainable production systems. The technique adapts easily to different climatic conditions and vineyard training systems.
