Earlier this month the Australian government announced it would set aside more than $1.7 million for projects under the Defeating the Weed Menace program, including nearly $280 000 for research on Parkinsonia, one of Australia’s worst weeds and ranked number one on the list of the 20 Weeds of National Significance. Dr Anantanarayanan Raman, senior lecturer in Ecological Agriculture at Charles Sturt University’s Orange Campus, said Parkinsonia is a problem throughout the tropical world where it spreads rapidly by seed. “Currently only integrated pest management and grazing by camels are being explored in Australia to control Parkinsonia. Biological control appears as a strong possibility to me, especially by using seed-feeding insects. One species of Asphondylia is known to infest Parkinsonia flowers and feed on them, which could lead to the total degeneration of the flowers. This species and other seed and flower-infesting insects need to be surveyed for their potential,” said Dr Raman.
