How to Hang scoutlabs Pheromone Delta Traps in vineyards

The European grapevine moth (Lobesia botrana) is a major pest in vineyards, with a taste for grapes that can seriously mess with both yield and quality. But fear not—pheromone traps are your go-to tool for keeping an eye on these sneaky moths and managing them effectively. Here’s how to set them up like a vineyard pro.

When to Hang the Traps

Lobesia botrana has several generations per year, so timing is everything. You’ll want to get those traps up before the first moths start flying, usually around bud break or as soon as spring temperatures start rising. Keep the traps up throughout the season, because this pest sticks around all the way through summer and into early autumn. The goal? Monitor them as they come and go to know exactly when to take action.

Trap Placement: Height and Position

For optimal results, hang the traps at around 1.5–2 meters (5–6 feet) high, right inside the vine canopy. You want the traps to be at grape-cluster height, because that’s where the moths are most likely to lay their eggs.

Make sure the traps are in well-ventilated spots and not blocked by leaves or branches—this lets the pheromone disperse properly and catch the moths’ attention. And if you can, go for shaded areas. Pheromones last longer in the shade, since direct sunlight speeds up their breakdown.

Trap Density and Spacing

• Monitoring: Use 1-2 traps per 5 acres.
• Higher Risk Areas: If you’re dealing with a known infestation or want to track things more closely, go for 3-4 traps per hectare. More traps mean better data on what’s happening with the moth population.
• Spacing: Keep traps at least 50 meters apart so the pheromone plumes don’t interfere with each other.

Avoid Row Edges:

• Don’t place traps at the edges of rows. Edge effects like wind and different pest activity can skew your results. Instead:
  • Place traps 2-3 rows in from the vineyard edge. This way, the pheromone spreads effectively through the vineyard canopy and gives you a more accurate picture of moth activity across the whole block.

Monitoring and Lure Maintenance

Good news: you don’t have to check scoutlabs traps manually. The scoutlabs mini snaps daily photos and sends the data straight to your app, so you’ll know exactly when a trap needs maintenance.

• Sticky sheet so full that you’d be surprised if our AI could still count that? Replace it! It needs to be changed ****once it’s filled up with moths and other debris. A clean surface means better moth-catching.
• Pheromone Lures: Change the lures every 4-6 weeks, depending on the manufacturer’s recommendations. If it’s particularly hot, the pheromone might degrade faster, so keep an eye on it during those high-temperature stretches.

Timing Control Measures

Pheromone traps give you a heads-up on when the moths are most active, which usually aligns with when they’re laying eggs on your grape clusters. This is the crucial moment for applying control measures, like mating disruption, biological controls (like natural predators or parasitoids), or insecticides.

Using pheromone trap data alongside degree-day models helps fine-tune the timing of interventions, ensuring you hit the pests when they’re most vulnerable (and your grapes are most in need of protection).

Why Trap Monitoring Matters

Pheromone traps are a key tool in managing Lobesia botrana populations. By capturing adult moths, these traps give you valuable insights into the timing and intensity of moth flights, so you can time your treatments with precision. With the right setup and regular maintenance, you’ll have a solid handle on keeping your vineyard safe from this damaging pest.

By tracking the pest count with your scoutlabs app and keeping those traps well-maintained, you can protect your vines, improve your harvest quality, and keep your grapes thriving all season long.
