Effectiveness of introduced biocontrol insects on the weed Parthenium hysterophorus (Asteraceae) in Australia.
Six species of insects and a rust fungus have been successfully established for biocontrol of the weed Parthenium hysterophorus L. in Queensland, Australia. Effectiveness of biocontrol insects was evaluated at two properties in Queensland during 1996-97 based on an exclusion experiment using insecticides. Parthenium-infested plots with and without biocontrol insects were sampled at monthly inte...
متن کاملComment on “Biosorptive uptake of Cr(VI) from aqueous solutions by Parthenium hysterophorus weed: Equilibrium, kinetics and thermodynamic studies”
Recently, Venugopal and Mohanty published the paper entitled as above [1]. In the section 3.9. Biosorption kinetics and rate determining step, Venugopal and Mohanty noticed that “the metal adsorption process depends on the number of metal ions present in the solution as well as the free sites on the biosorbent surface. The pseudosecond order equation is:” with Eq. (6). The pseudo-second-order k...
متن کاملEffects and Management of Parthenium hysterophorus: A Weed of Global Significance
Congress grass, Parthenium hysterophorus L., of the family Asteraceae (tribe: Heliantheae), is an erect and much branched annual or ephermeral herb, known for its notorious role as environmental, medical, and agricultural hazards. It is believed to have been introduced into India and Australia from North America and in the last few years the weed has emerged as the seventh most devastating weed...
متن کاملThe Combined Effect of Biological Control with Plant Competition on the Management of Parthenium Weed (parthenium Hysterophorus L.)
Parthenium hysterophorus L., (Asteraceae) commonly known as parthenium weed, is a highly invasive plant that has become a problematic weed of pasture lands in Australia and many other countries around the world. For the management of this weed, an integrated approach comprising biological control and plant competition strategies was tested in southern central Queensland. Two competitive pasture...
متن کاملGenetic Structure of Invasive Weed Parthenium hysterophorus in Australia and Pakistan
Understanding the patterns of genetic structure in the introduced range of invasive species can help elucidate invasion histories and levels of gene flow among populations. Parthenium weed (Parthenium hysterophorus L.; PW) is native to the Gulf of Mexico and central South America but has become globally invasive during the last three decades and little is known about the genetics of this specie...
