New Latin Aphis, Aphid-, type genus.(American Heritage® Dictionary of the English Language, Fourth Edition)
Modern Latin aphides, coined by Swedish botanist Carolus Linnaeus in 1758. His inspiration for the name remains unclear. OED suggests a connection to Ancient Greek αφειδής (apheidēs, "unsparing, lavishly borrowed") in reference to the insects' voracity or rapid rate of production. (Wiktionary)
