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

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
![Page 36: Abutilon theophrasti a new host for Orobanche aegyptiaca in Israel](https://reader035.vdocuments.us/reader035/viewer/2022062805/56814dc7550346895dbb194d/html5/thumbnails/36.jpg)
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
