Lophocampa sobrina

Lophocampa sobrina is a moth species belonging to the order Lepidoptera, family Erebidae, and subfamily Arctiinae. These insects, often referred to as tiger moths, are known for their hairy larvae which can cause significant damage to foliage when populations reach high densities.

This pest is primarily polyphagous, targeting a wide range of deciduous trees and shrubs, including various fruit-bearing species. The larvae feed aggressively on leaf tissue, and in scenarios with heavy infestations, they can strip entire branches of their foliage, severely impacting plant health.

The life cycle follows a complete metamorphosis: egg, larva, pupa, and adult. Females typically deposit egg clusters on the underside of host leaves. Once hatched, the larvae go through several developmental stages, or instars, feeding throughout the growing season before eventually spinning cocoons to pupate in sheltered locations.

Damage caused by this insect is characterized by partial or complete defoliation. This reduction in the leaf surface area inhibits the plant's ability to perform photosynthesis, which weakens the tree, stunts growth, and can result in significant yield losses for commercial orchards and backyard gardens alike.

Effective management strategies include the following:

• Regular field scouting to identify egg clusters and young larvae.
• Manual removal and destruction of caterpillar webs or clusters to prevent spread.
• Application of microbial insecticides based on Bacillus thuringiensis during early larval stages.
• Implementation of chemical controls using targeted insecticides only when infestation levels exceed economic thresholds.
