| Abstract: | A species of the flea beetle (Epitrix sp.) transmitted Andean potato latent virus (APLV) from Datura stramonium to D. stramonium, Nicandra physalodes and potato, and from N. physalodes to N. physalodes and D. stramonium. Although the acquisition and inoculation feeding times used were varied, this transmission always occurred at low efficiency. By contrast, APLV was very readily transmitted in tests in which infected plants of D. stramonium, N. physalodes, Nicotiana bigelovii and potato were brushed against healthy plants of one or more of these species. A low level of seed transmission of APLV occurred in potato. |
