Fruit fly Neotephritis mundelli

Neotephritis mundelli is a species of fruit fly belonging to the family Tephritidae (order Diptera). This insect is known for its specialized feeding habits, specifically targeting the flower heads of plants within the Asteraceae family.

In its natural habitat, the pest predominantly attacks native composite plants. While some species in this family are recognized as biological control agents for weeds, Neotephritis mundelli can emerge as a pest when agricultural crops or ornamental Asteraceae are cultivated in its native range.

The life cycle involves complete metamorphosis, consisting of the egg, larval, pupal, and adult stages. Females lay eggs inside the developing buds or flowers. Once hatched, the larvae feed internally on the receptacle and developing seeds, effectively hollowing out the flower head.

The damage caused by this pest is primarily reproductive, leading to poor seed set and malformed flower heads. Infested plants show signs of premature decay, stunted growth of the floral parts, and a significant decrease in viable seed production, which can cause economic losses in seed-producing fields.

Effective management strategies include:

• Monitoring adult activity using yellow sticky traps placed near the crops.
• Sanitation practices, such as removing and destroying infested flower heads before larvae pupate.
• Targeted applications of insecticides during the oviposition period.
• Implementing cultural practices to disrupt the synchronization between the pest life cycle and crop development.
