Temperature in the Life History of Rhopalosiphum subterraneum Mason, a New Cotton Root Aphid

The injury caused by root-infesting aphids is frequently overlooked because of their subterranean habitat, and this often results in the wrong diagnosis of plant troubles. The cotton root aphids form a group of subterranean species whose economic importance has been somewhat underestimated. Certainly in some places in the Coastal Plains section of the Cotton Belt the insects of this group cause losses to the cotton crop second only to those by the boll weevil, Anthonomus grandis Boh.
