Acidoxantha bombacis

Systematic position. Acidoxantha bombacis is a species of fruit fly belonging to the order Diptera and the family Tephritidae. These insects are specialized phytophagous pests that predominantly target plants within the Malvaceae family.

Host crops and impact. The primary host for this pest is cotton (Gossypium). By attacking the reproductive structures of the plant, the larvae cause direct damage to the developing bolls, which significantly affects the yield and fiber quality.

Biology and life cycle. The life cycle involves a complete metamorphosis. The adult female deposits eggs into the buds or young fruit. Upon hatching, the larvae bore into the tissue, where they feed and develop, sheltered from external environmental factors.

Damage symptoms. Typical damage includes the premature shedding of buds and the internal decay of cotton bolls. Infested bolls often show signs of malformation and discolored fiber, rendering the product commercially unviable if left untreated.

Control measures. Integrated Pest Management (IPM) is crucial for controlling Acidoxantha bombacis. Recommended strategies include:

• Deep plowing post-harvest to expose puparia to predators.
• Monitoring adult populations with traps.
• Applying systemic insecticides during peak infestation periods.
• Removing infested plant debris to reduce overwintering sites.
