Fungus Gnats

The larvae of these flies live in the soil and feed on organic matter or fine root hairs, which can weaken the melon plant's stability. They are attracted to the consistently moist soil often required for Honeydew production.

Very Common

How to confirm: Set a yellow sticky trap near the base of the plant to confirm the presence of small flying insects.

1 Deploy yellow sticky traps to capture the adult flying gnats and break the reproductive cycle.
2 Allow the top inch of soil to dry out completely between waterings to eliminate the moist environment required for larvae survival.
3 Apply a microbial-based soil drench to target the larvae living in the organic matter of the soil.

Blackberry Fruit Fly (Drosophila species) infestation

While often associated with decaying fruit, these flies can be attracted to the melon vines if there is overripe or rotting fruit nearby. They lay eggs that can lead to secondary fungal infections in the melon flesh.

Common

How to confirm: Inspect any fallen or bruised melons for small puncture marks or signs of soft rot.

1 Remove and dispose of any overripe, bruised, or rotting melons from the vicinity to eliminate the primary breeding site for the flies.
2 Deploy yellow sticky traps near the melon vines to capture adult flies and monitor the population levels.
3 Apply an organic insecticide spray to the vines to target any remaining larvae or adults and prevent secondary fungal infections.

Scirtothrips (Thrips) infestation

While thrips are tiny, they can appear as dark specks moving on leaves. They feed on the epidermal cells of the Honeydew leaves, causing silvery scarring and stunting growth.

Common

How to confirm: Tap a leaf over a white piece of paper to see if tiny, fast-moving dark specks fall off.

1 Apply an organic insecticide to eliminate the thrips population and protect the melon leaves from further feeding damage.
2 Place yellow sticky traps near the plant to capture adult thrips and monitor the severity of the infestation.
3 Inspect the undersides of leaves for silvery scarring and remove heavily infested foliage to prevent the spread to healthy parts of the plant.
