At the recently concluded Botanical Society of America meeting Roshaniza Rosili (PhD student at University of Brunei- Co supervised by Kushan Tennakoon and Faizah Metali) reported that the photosynthesis of alien invasive Acacia mangium seedlings can be significantly reduced due to parasitism by native Cassytha filiformis. This suggest that the spread of these alien invasive tree seedlings in the field could be controlled by C. filiformis infection.
