Acrotomopus

Acrotomopus is a genus of weevils (family Curculionidae) within the order Coleoptera. These beetles are recognized as significant pests that specialize in feeding on specific plant hosts, often causing economic losses in agricultural sectors that rely on Malvaceae crops, such as cotton.

The damage caused by Acrotomopus is primarily directed at the reproductive organs of the host plants. By targeting buds, flowers, and developing fruit (bolls), the larvae significantly impact the plant's yield potential, making this insect a primary concern for integrated pest management programs in infested regions.

The biological life cycle follows the standard development stages of weevils: egg, larva, pupa, and adult. The females oviposit into the tissue of the host plant, and the larval stage is typically spent entirely within the plant structure, which provides a natural refuge against environmental stressors and some contact insecticides.

In terms of crop impact, the damage is characterized by:

• Premature shedding of flower buds.
• Internal tissue destruction leading to aborted development of fruits.
• Reduced physiological vigor of the host plant.
• Economic yield loss due to reduced quantity and quality of harvestable fiber.

Effective control measures require a multi-faceted approach. Cultural practices such as crop rotation, destruction of crop residues after harvest, and deep plowing to disturb overwintering sites are critical. Furthermore, monitoring population levels using pheromone traps allows for the precise and judicious application of insecticides, minimizing impact on beneficial insects while protecting the crop during peak vulnerability.
