Summary.1 An account is given of some preliminary experiments with insects as transmitters of potato mosaic disease. The various types of insect‐proof cage which have been used in these experiments are described. 2 The following insects were used in the inoculations: A phididae . Myzus persicae.Macrosiphum gei (= solanifolii ). Myzus Circumflexus. A leurodes , White‐fly. Asterochition vaporariorum. C apsidae . Calocoris bipunctatus.Lygus pabulinus. T yphlocybidae , Leaf‐hoppers. Zygina pallidifrons.Eupteryx auratus.3 The aim of the experiments is definitely to identify what insects of those normally attacking the potato are disseminators of virus disease. 4 Infected insects were placed both upon the sprouts of tubers and upon the haulm; the latter is the only satisfactory method for insects other than aphides. 5 Successful transmission of mosaic disease was obtained in 1925 by means of the aphides Myzus persicae and Macrosiphum gei . Some evidence of infection by means of Aslerochiton vaporariorum (greenhouse white‐fly) and the leaf‐hoppers Zygina pallidifrons and Eupteryx auratus wars also obtained; further work with these insects is required before definite conclusions are drawn. The capsid bugs Lygus pabulinus and Calocoris bipunctatw failed entirely to transmit the disease.
