Cheirolasia

Systematic position: The genus Cheirolasia belongs to the order Coleoptera and the family Cetoniidae (flower beetles). These insects are recognized as specific pests in their natural habitats, primarily distributed across tropical African regions, exhibiting complex morphological adaptations common to the Scarabaeoidea superfamily.

Crops damaged: This pest poses a threat to various high-value tropical crops, with a notable impact on cocoa and coffee plantations. Additionally, they are known to feed on the reproductive parts of flowering plants, leading to the destruction of buds and flowers, which directly hinders fruit set.

Biology and lifecycle: The lifecycle includes a complete metamorphosis, consisting of four stages. Larvae typically develop in decaying plant material or moist forest soil, serving as decomposers in the ecosystem. Adults emerge during the wet season, exhibiting peak activity levels that align with the flowering periods of their host plants.

Damage and economic significance: The adult beetles cause the most significant damage by feeding on foliage, buds, and fruit clusters. Defoliation reduces the plant's ability to produce energy, leading to stunted growth. In severe infestation cases, the damage to blossoms can result in total yield loss for the season.

• Implementing pheromone traps for early detection and population monitoring.
• Targeted chemical application using insecticides during the peak of adult emergence.
• Sanitation practices, such as removing rotting wood where larvae congregate.
• Utilizing biological control agents, including entomopathogenic fungi, to reduce larval survival rates.
