Clepsis peritana

Clepsis peritana belongs to the order Lepidoptera, specifically the family Tortricidae. This moth species is a known polyphagous pest, meaning its larvae feed on a wide variety of herbaceous and woody plant hosts, posing a significant challenge to agricultural productivity and ornamental nurseries.

The pest primarily targets crops such as strawberries, various vegetables, and broad-leaf ornamental plants, as well as common weeds. The larvae feed on foliage, developing fruits, and floral buds, which leads to stunted growth and a substantial reduction in the marketability of the harvested crops.

The biology of the pest is highly dependent on ambient temperature. Females lay eggs in clusters, typically on the underside of leaves. Upon hatching, the larvae undergo several instars, feeding on plant tissues and skeletonizing the foliage. Depending on the local climate, the species can complete multiple generations within a single growing season.

A distinctive sign of infestation is the presence of fine silk webbing. The larvae use this silk to tie leaf margins together or bind fruits to nearby leaves, creating protected shelters for feeding. This damage often ruins the outer skin of fruits, which subsequently facilitates the entry of secondary fungal and bacterial pathogens.

Control strategies require an integrated approach: cultural practices such as field sanitation and weed control, biological control using beneficial insects (parasitoids), and the targeted application of insecticides during the peak larval emergence phase. Routine monitoring with pheromone traps is highly recommended to manage population densities effectively.
