The tomato yellow leaf curl disease is caused by a hitherto undescribed virus (TYLCV), which attacks tomato and Datura stramonium plants in Israel. The virus, transmitted by the tobacco whitefly, is persistent in its vector, but not for life. A virus-acquisition access lasting 24 hours renders the whitefly inoculative for an average period of 10-12 days. During that period the vector is unable to compensate for its steadily decreasing inoculativity by re-acquiring the virus from a source plant, until it first completely ceases to transmit the virus. Only after such a cessation is the vector able to begin re-acquiring the virus, and thereby regain its inoculative potential as during the previous cycle of acquisition/inoculation. © 1964 North-Holland Publishing Company.
