Diaphania nitidalis

Definition

A tropical moth species (Lepidoptera: Crambidae) whose larvae, known as pickleworms, are major agricultural pests of cucurbit crops. Native to warmer regions and extending into the southern United States, the species cannot survive cold temperatures; late-season plantings suffer more damage than early crops. The larval stage bores into fruits and stems of squash, cucumber, melon, and related plants, causing direct yield loss.

Etymology

Example

Diaphania nitidalis populations build through the growing season in Florida, with squash plantings in August showing 60–90% fruit infestation compared to negligible damage in March plantings.

Usage Notes

The common name "pickleworm" refers strictly to the larval stage; adults are small, pale moths rarely noticed in the field. In cooler temperate zones, the species appears only as a seasonal migrant or greenhouse invader, not an established resident.
