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 ...

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.

The evolutional significance of the chromosomes of Aphididae
Journal of Morphology, 1931AbstractAn investigation into the number of chromosomes in thirty‐seven species of Aphidiae belonging to twenty‐seven geaera has shown that there is but one sex chromosome in the male cells of all but one species of Aphididae. That exceptional species is Euceraphis betulae Koch.The number of chromosomes and body characters are so closely correlated ...

The Aphididae of the Canadian Arctic (Homoptera)
The Canadian Entomologist, 1963AbstractEighteen species are listed of which eight are described as new. Most of these species were collected in the more southerly parts of the Canadian Arctic, but two species were collected at Lake Hazen which is situated in the extreme northeastern portion of Ellesmere Island.
