Recifera coronifera

Recifera coronifera is a significant agricultural pest belonging to the order Lepidoptera and the family Pyralidae. As a specialized feeder, it focuses its impact on various legume crops, making it a critical concern for producers aiming to maintain high-quality grain yields in infested regions.

The primary hosts for this moth include various species of pulses, particularly peas and beans. The pest is recognized for its ability to infest crops during the reproductive stage, directly compromising the developing seeds and leading to substantial economic losses for farmers if left unmanaged throughout the growing season.

The biological cycle of this pest involves complete metamorphosis, covering egg, larval, pupal, and adult stages. The larval stage is the most destructive period, as the caterpillars bore into the seed pods to feed on the interior. This behavior not only damages the individual seeds but also allows the larvae to remain shielded from environmental stressors and many traditional pesticides.

Damage symptoms primarily include hollowed-out seeds, exit holes, and internal contamination with frass, which severely degrades the grain quality. In cases of high infestation, the damage can extend to the total loss of commercial value of the crop, making it unfit for both processing and future planting due to significantly reduced germination rates.

Effective management strategies for controlling this pest include:

• Integrated Pest Management (IPM) practices focusing on crop rotation;
• Regular field scouting and monitoring with pheromone traps;
• Timely application of targeted systemic insecticides during peak moth activity;
• Post-harvest cleaning and proper drying of grain to prevent further larval development.
