Abstract
1. Reference is made to the proven capacity of aphides of the genus Capitophorus to transmit virus disease among strawberries, and attention is drawn to the confusion existing as to the actual synonymy of the insect principally concerned.2. For the first time sexual and asexual forms of the species commonly present in England have been observed together. Evidence is considered which suggests that the aphis is Capitophorus fragariae, Theo., and that American forms are in reality other, but closely related, species.3. The incidence of the aphis in the field is considered, and the biology as observed in field and laboratory is discussed.4. The economic significance of the aphis is referred to, and attention is drawn to the practical difficulties attending efforts to keep it in control, particularly in commercial strawberry-growing areas.
