Adoretus lasiopygus

Adoretus lasiopygus is a species of beetle belonging to the family Scarabaeidae (order Coleoptera). Often categorized as a significant pest, this beetle is known for its nocturnal feeding habits and its ability to cause severe defoliation in various types of vegetation across its geographic range.

This beetle species affects a wide variety of host plants, including fruit trees, grapevines, and various ornamental shrubs. Its polyphagous nature allows it to transition from wild vegetation to commercial crops, making it a persistent challenge in orchards and gardens throughout the growing season.

The biological cycle follows a complete metamorphosis: egg, larva, pupa, and adult. Adult beetles are primarily nocturnal, spending daylight hours hiding in the soil or under leaf litter. Larval development occurs underground, where they feed on organic matter and plant roots, often causing damage to young saplings without being immediately observed.

The damage caused by adults is characterized by intense leaf skeletonization. They consume the leaf tissue between the veins, leaving behind only a network of vascular structures. Severe infestations can result in total defoliation, which hampers the photosynthetic capacity of the plant, stunts its overall growth, and drastically reduces annual yield.

• Deploying light traps to attract and capture adults at night.
• Applying systemic insecticides to foliage during peak beetle activity.
• Implementing deep cultivation of the soil to disturb larval development.
• Using biological control agents such as entomopathogenic nematodes.
• Maintaining field sanitation to minimize sheltered areas for the beetles.
