Guava moth caterpillars bore into the fruit of guavas, feijoas, stone fruits and citrus, damaging and rotting the fruit.
Identify the problem
You may notice the presence of guava moth caterpillars by small entry holes in the skin of the fruit and tunnels with larvae inside. Infestation may also make the fruit appear bruised and cause it to drop early.
- When susceptible fruit is still green, and before it would be attacked by the guava moth caterpillar, encase the fruit, or the whole tree/bush, in a fine mesh net to keep the moths out.
- Monitor for the presence of moths using a guava moth pheromone trap.
- As soon as moths are caught in the traps apply Organic Caterpillar Bio-Control to control caterpillars before they bore into the fruit. Re-apply at 7 day intervals until moths are no longer caught.
- Clear up all fallen fruit and mow the areas below trees to prevent guava moth pupating in the leaf litter.
