Yellow-collared scape moth

The yellow-collared scape moth (Cisseps fulvicollis) is a member of the Erebidae family, specifically the Arctiinae subfamily. While often considered a minor pest, in favorable environmental conditions, its larvae can reach population levels that pose a risk to various plant species.

This pest affects a range of herbaceous plants. The primary damage is caused by the larval stage, which feeds voraciously on leaves. By skeletonizing the foliage or consuming entire leaves, the larvae reduce the plant's ability to perform photosynthesis, which is critical for biomass accumulation and final crop yield.

The life cycle of Cisseps fulvicollis consists of four distinct stages: egg, larva, pupa, and adult. The females typically deposit eggs on the undersides of host plant leaves. Upon hatching, the larvae exhibit high feeding activity, passing through several instars before constructing a protective, silken cocoon to transition into the pupal stage.

The impact of this pest is most evident during the active growth phases of the host plants. Heavy infestations can lead to significant defoliation, which causes stunted growth, weakened plant immunity, and, in severe cases, the death of young seedlings, ultimately leading to yield loss for the agricultural producer.

Effective management and control strategies for this moth involve:

• Routine scouting to identify larval presence in the early stages of development.
• Management of weeds that serve as alternate hosts for the moths.
• Application of selective insecticides when infestation thresholds are exceeded.
• Maintaining soil health and crop vigor through proper fertilization to improve the plant's recovery capability.
