NoPests® Guava Moth Pheromone Trap
Description
Targeted monitoring and lifecycle disruption for Guava Moth (Coscinoptycha improbana)
The NoPests® Guava Moth Pheromone Monitoring Trap is a highly targeted monitoring tool designed to attract and capture male guava moths, helping growers track pest activity and reduce successful mating. By intercepting males, the reproductive cycle is disrupted, leaving females unfertilised and reducing future larval pressure within fruit.
Guava moth adults are small, black-and-white speckled moths with an approximate 15 mm wingspan and a short adult life of around two weeks. Eggs are laid in clusters on host fruit and hatch into larvae that bore directly into developing fruit, where they feed internally. This feeding causes internal rotting, brown patches, frass, mould development, and can result in premature fruit drop and unmarketable produce.
Larvae pass through four instars, remaining hidden within fruit until maturity. Once fruit falls to the ground, larvae exit to pupate in debris beneath host trees, continuing the lifecycle. Because damage occurs internally and early, effective monitoring is criticalfor timely intervention.
When to Use
Install traps at bud break, before fruit becomes susceptible
Traps should be operating before adult moth flight begins
Check traps weeklyand record moth counts to track population trends
Trap Placement
Hang traps near the top of the canopy, approximately 2–3 metres above ground
Distribute traps uniformly throughout the orchard
Place additional traps in known hot spots
Never use fewer than two traps per orchard
Recommended trap density:
< 12 ha:1 trap per 4 ha
12–32 ha:1 trap per 3 ha
> 32 ha:Increase trap numbers proportionally to ensure coverage
Assembling the Trap
Unfold one sticky insertand place it sticky-side up inside the trap
Open one foil sachet and place one PHEROCON® pheromone lurein the centre of the sticky base
Use tweezersto avoid contamination
Insert the wire hanger and hang the trap as described above
Ongoing Maintenance
Inspect traps at least weekly
Remove trapped moths to maintain full sticky surface effectiveness
Replace sticky inserts and pheromone lures every 4 weeks, or sooner if contaminated by dust or insect debris
Dispose of used components in general rubbish
Important Use Notes
Do not cut or open the PHEROCON® lure
The pheromone is designed for slow, controlled release through the polymer vial
Only open lure sachets when ready to use
Use one pheromone lure per trap only
