Pentalonia
Pentalonia is a genus of aphids in the family Aphididae, established by Coquerel in 1859. The genus contains at least four recognized species distributed across tropical and subtropical regions. Pentalonia nigronervosa, the banana aphid, is the most extensively studied species due to its role as the primary vector of Banana Bunchy Top Virus (BBTV), a devastating disease of banana crops worldwide. Recent morphometric and molecular studies have clarified that P. nigronervosa and P. caladii are distinct cryptic species with different host plant preferences.
