Ploidy level effect of alligator weed on the phytophagous insects and phytopathogens.
The alligator weed, Alternanthtera philoxeroides, is an allopolyploid from South America and invasive in several regions in the world. This weed invades agricultural and natural ecosystems such as rice, soybeans, sunflower and corn.
The goal of this project is to investigate the ploidy level effect on its genetic variability and on its natural enemies, phytophagous insects and phytopathogens. This project allows expanding the theoretical framework of the allopolyploids weeds from the study of a particular case, their interactions with insects and phytopathogenic specialists and their potential for invasion. It is also expected to expand management strategies through biological control.
