Aphids (Hemiptera: Aphididae) are a lineage of ~5200 plant‐feeding insects most abundant in temperate regions. The diversification of aphids is thought to be a rapid radiation, whereas abiotic and biotic factors heavily influence the morphologies.

The Aphididae, or aphids, is a large family of nearly 4000 small and soft-bodied insects in the superfamily Aphidoidea. More than 25 aphid species have been found in citrus orchards throughout the world, of which some are of economic importance and others probably occur there sporadically.

Canadian Journal of Zoology, 1969
Idiograms of the somatic chromosomes of 110 species of Aphididae are presented. It is concluded that although 2n chromosome numbers have stabilized in some genera at 8, 10, or 12, there has been so much fragmentation, and possibly also fusion, that there is no evidence to suggest a primitive number for aphids, nor to assist in studies on their ...

Evaluation of Tactics for Management of Sugarcane Aphid (Hemiptera: Aphididae) in Grain Sorghum
Journal of Economic Entomology, 2019The invasive sugarcane aphid, Melanaphis sacchari (Zehntner), is a devastating new pest of grain sorghum. Studies were conducted utilizing an integrated approach of four management tactics: planting date, insecticidal seed treatment, a foliar-applied ...

Effects of beauvericin on Schizaphis graminum (Aphididae)
Journal of Invertebrate Pathology, 2002The effects of beauvericin, a toxic fungal metabolite common contaminant of maize and wheat, on aphid fitness were studied in three consecutive generations of females. Aphids were reared on wheat leaves inserted into a sandy substratum wetted with a solution of beauvericin.
