How to Hang Pheromone Traps for Navel Orangeworm (Amyelois transitella) in Almond and Pistachios Orchards

The navel orangeworm (Amyelois transitella) is a serious pest that targets nut and fruit orchards, especially in crops like almonds, pistachios, and walnuts. The larvae love to feast on your nuts and fruits, so keeping an eye on their population is crucial. Here’s how to set up pheromone traps to monitor and manage these moths effectively.

When to Hang the Traps

Navel orangeworms typically start flying in spring, once the temperatures begin to rise. To stay ahead, it’s key to hang your traps before the first generation of moths starts flying—around March or April, depending on where you’re located. Keep those traps up throughout the growing season, since multiple generations of this pest will keep popping up.

Trap Placement: Height and Position

Hang your pheromone traps at around 1.5–2 meters (5–6 feet) above the ground, ideally inside the tree canopy where the moths will be buzzing around, looking to lay their eggs. Position the traps near nut clusters or the fruiting zones of the trees since that’s where they’ll be aiming to do the most damage.

For best results:

• Avoid placing traps right at the orchard edges or in overly shaded areas. Moths prefer open, airy spots in the canopy.
• Make sure traps are in well-ventilated areas to let the pheromone plume spread nicely and attract the moths.

Trap Density and Spacing

• Monitoring: Use 1 trap per 4-8 hectares.
• If you’re dealing with a larger orchard or have had past issues with navel orangeworm, consider increasing the number of traps for better coverage.
• Space the traps at least 50-100 meters apart to avoid pheromone plume overlap and keep the traps working effectively.

Monitoring and Lure Maintenance

No need to run around checking the traps every day—scoutlabs mini takes care of it. It snaps daily photos and uploads the data to your app, showing which traps need attention.

• Change the pheromone lures every 4-6 weeks, especially in hotter weather when the pheromones break down faster.

Timing Control Measures

The data from your pheromone traps will show when navel orangeworm populations are spiking, giving you a heads-up for when egg-laying is happening. That’s your cue to apply control measures like insecticide sprays or biological control methods. Catching the moths at peak activity means fewer larvae infesting your crops later.

Pair the trap data with degree-day models to fine-tune your timing and make sure your treatments hit the pest at its most vulnerable stage.

Why Trap Monitoring Matters

Using pheromone traps for the navel orangeworm gives you early, accurate insights into pest activity, so you can act fast and prevent crop damage. Plus, with the scoutlabs app, you’re able to reduce unnecessary pesticide use and focus your treatments where they’ll be most effective.

By setting up and maintaining pheromone traps properly, you’ll protect your orchard from navel orangeworm infestations and improve both the health of your trees and the quality of your harvest.
