Pepper Maggot, Zonosemata electa, in Sweet (Bell) Pepper
The pepper maggot, Zonosemata electa, is a significant pest of bell pepper in eastern North America, having transitioned from its native wild host, the horse nettle, to domesticated solanaceous plants like bell pepper and eggplant. Infestation levels can be alarming, with near-total crop loss possible from a single maggot per fruit. Control methods primarily involve insecticide applications, posing challenges for organic producers. The pest has a single annual generation, overwintering as a pupa in soil. Monitoring adult populations using yellow sticky traps and oviposition scars is essential for effective management. Cultural practices such as field sanitation, crop rotation, and the eradication of alternate hosts are crucial in mitigating damage. Additionally, trap cropping with hot pepper varieties and perimeter sprays have shown success in reducing damage to bell peppers. Various insecticides are available for pre-emptive control, emphasizing the importance of monitoring to optimize application timing.
