The red hairy caterpillar, also known as Amsacta albistriga, is a moth larva found primarily in southern India. It's considered a major agricultural pest due to its feeding habits. Reddish-brown with a black band on its side and long, reddish-brown hairs all over its body. As a moth, it has white wings with brown streaks and markings.
Identification:
- Reddish brown body with black bands on both ends.
- Covered in long, reddish brown hairs all over its body
- Can grow up to 5 cm in length when fully grown
Environmental favorable factors for pests/Diseases:
- Temperature: Red hairy caterpillars are most active in warm weather, with optimal temperatures for development ranging from 25-30°C
- Humidity: Moderate to high humidity levels favor red hairy caterpillar survival and development. Dry conditions can be detrimental to their populations.
Symptoms of Pest/Disease:
- Leaf scraping and skeletonization: In their young stages, the caterpillars feed on the undersides of leaves, leaving behind a thin, papery upper layer.
- Extensive defoliation: As the caterpillars mature, their appetite grows. They will begin to consume all parts of the plant, including leaves, stems, flowers, and even developing pods. This can lead to complete defoliation of the plant, leaving only the main stem.
