Why does your Melon Exalto F1 have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyThe larvae of fungus gnats live in organic-rich, moist soil and feed on decaying matter and fine root hairs of the melon plant. The adult tiny black flies emerge to lay eggs, often signaling that the soil substrate is excessively damp.
While often associated with ripening fruit, these flies are attracted to the fermenting sugars in overripe or bruised melon flesh. If the flies are hovering specifically around the developing fruit rather than the soil, they are likely seeking oviposition sites.
While the primary symptom is serpentine tracks on leaves, certain fly species can attract secondary scavengers and small flies to the plant. The presence of tiny flies often coincides with the decaying organic material left by larval feeding.
