What is the scientific name of the sweet potato weevil?

Leptinotarsa decemlineata
Cylas formicarius elegantulus
Both A and B
None of the above

The correct answer is: Cylas formicarius elegantulus

The sweet potato weevil is scientifically known as Cylas formicarius elegantulus. This classification comes from the family Brentidae, and it specifically refers to the beetle that is known for infesting sweet potatoes. Understanding the taxonomy is crucial because it helps identify the specific pests that affect agricultural crops and informs proper pest management strategies. The other option, Leptinotarsa decemlineata, refers to the Colorado potato beetle, which is a different pest that primarily affects potato plants rather than sweet potatoes. Distinguishing between these pests is important for effective pest control measures, as the management strategies for each may differ significantly. Recognizing the correct scientific names aids in communication about agricultural practices and pest control efforts.
