Pemphigus monophagus
Maxson, 1934
Pemphigus monophagus is a root-feeding in the Aphididae, described by Maxson in 1934. It belongs to the Pemphigus, which comprises aphids that typically form galls or inhabit root systems of plants. Like other Pemphigus , it is frequently misidentified in agricultural contexts and has been confused with other root-infesting aphids in online discussions.

Identification
Pemphigus monophagus is morphologically similar to other Pemphigus , making field identification difficult. Accurate identification requires examination of microscopic features and is typically confirmed through taxonomic keys or molecular analysis. It is distinguished from the rice root aphid (Rhopalosiphum rufiabdominale) by generic-level characters: Pemphigus species possess shorter with fewer segments and distinct cornicle structure compared to Rhopalosiphum.

Human Relevance
Pemphigus monophagus has been erroneously cited in agricultural literature and online sources regarding root on cannabis crops. These reports actually refer to the rice root aphid (Rhopalosiphum rufiabdominale), not Pemphigus . This misidentification has propagated through internet forums and informal publications, leading to confusion in pest management recommendations.
Similar Taxa

- Pemphigus populicaulisSimilar gall-forming or root-feeding within the same ; identification relies on association and detailed morphological analysis
Misconceptions
Pemphigus monophagus has been incorrectly implicated as a pest of Cannabis sativa in numerous online sources and informal agricultural publications. These reports actually describe by the rice root aphid (Rhopalosiphum rufiabdominale). The error appears to stem from misattributed photographs and uncritical repetition of unverified claims across internet forums. No verified evidence confirms P. monophagus development on cannabis.
