Abutilon theophrasti a new host for Orobanche aegyptiaca in
Israel
Egyptian broomrape (Orobanche aegyptiaca) parasitizes a broad host rang of agricultural crops:
•Legumes•Solanaceae (eggplant, tomato, tobacco, potato and capsicum peppers)•Umbellifferae (carrot, parsley, celery)•Cruciferae (oil seed rape, cabbage) lettuce•Compositae (sunflower)
In summer 2006 we found that O. aegyptiaca is capable to parasitize Abutilon theophrasti,
a Malvaceae specie never before mentioned as a host in literature

2008 same location – Watermelon remain infested with
A. theophrasti and O. aegyptiaca
Tabor mountain
August 2008
On summer 2009 we found in Olive orchard with a history of high infestation of
O. aegyptiaca that Malva nicaeensis could be another Malvaceae host too!
O. Aegyptiaca on Solanum nigrum
The ability of O. aegyptiaca to detect, recognize and parasitize A. theophrasti, presents an
immediate threat to other Malvaceae species like cotton, okra and ornamentals belonging to this
botanical family
