Introduction

Several investigators have recorded the experimental transmission of virus diseases of plants to a large number of species in different genera of many families. A review of the literature on the host range of certain virus diseases shows an extensive host range as determined by experimental infection, but the reported natural host range is often limited, as illustrated in table 1.

The natural infection of ornamental flowering plants with curly top has already been reported in a previous paper.⁽²⁷⁾4 A list of the plants experimentally infected, but without details of the experiments or description of the symptoms, was published in the Plant Disease Reporter.⁽⁷⁾ The details and results of the experiments performed to experimentally infect ornamental flowering plants with curly top are given in the present paper. No intensive investigations have been conducted to determine which plants are resistant or immune to curly top; only plants experimentally infected with the disease are reported in this paper. The symptoms on the susceptible host plants are briefly described. The longevity of the last living male and female beet leafhopper, Eutettix tenellus (Baker), was ascertained on inoculated plants and a record was kept of all plants on which the leafhopper completed its life cycle.
