Pest identification
What's eating my cantaloupe?
Striped and spotted cucumber beetles (Acalymma vittatum / Diabrotica undecimpunctata)
Signs: Feeding scars on leaves and fruit skin; bacterial wilt infection causes vines to collapse within days.
Control: Use row covers until flowering; apply pyrethrin or kaolin clay; remove debris in fall to reduce overwintering adults.
Aphids (Aphis gossypii — melon aphid)
Signs: Sticky honeydew, sooty mold, and mosaic virus transmission leading to mottled, stunted foliage.
Control: Spray with insecticidal soap or neem; release lacewings or parasitic wasps; avoid over-applying nitrogen fertilizer.
Squash vine borer (Melittia cucurbitae)
Signs: Larvae bore into the crown of the vine, causing sudden wilting with frass visible at the entry point.
Control: Delay planting to miss the adult flight; wrap stems; apply Bt to base of plants; destroy infested vines promptly.
Pickleworm (Diaphania nitidalis)
Signs: Caterpillars bore into fruit, leaving frass-filled holes; worst in southeastern US in late summer.
Control: Apply Bt (Bacillus thuringiensis) sprays at egg hatch; remove infested fruit immediately; use row covers early.

Cantaloupe pests — FAQ
What is eating my cantaloupe?
Cantaloupe faces the same core threats as other cucurbits: cucumber beetles (which spread bacterial wilt), aphids, and squash vine borers. Pickleworms damage fruit in the South. Protect transplants with row covers, remove them at flowering, rotate crops yearly, and scout for beetles from the moment plants emerge.
