番茄黄化曲叶病是由一种迄今尚未描述的病毒（TYLCV）引起的，该病毒攻击以色列的番茄和曼陀罗植物。这种由烟草粉虱传播的病毒在其载体中是持久的，但不是终身的。持续24小时的病毒获取访问使粉虱的平均接种期为10[长破折号]12天。在此期间，载体不能通过从源植物重新捕获病毒来补偿其稳定降低的接种率，直到它首先完全停止传播病毒。只有在这样的停止之后，载体才能够开始重新获得病毒，从而恢复其在前一个获得/接种循环期间的接种潜力。|| 摘要编辑：作者
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[long dash]12 days. During that period the vector is unable to compensate for its steadily decreasing inoculativity by reacqulring 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 reacquiring the virus, and thereby regain its inoculative potential as during the previous cycle of acquisition/inoculation. || ABSTRACT AUTHORS: Authors
