It originated in South America, but has spread to many parts of the world and is considered an invasive species in Australia, China, New Zealand, Thailand, and the United States. Alligator weed can grow in a variety of habitats, including dry land, but is usually found in water. It may form large interwoven mats over the water or along shorelines. Alligator weed stems are long, branched, and hollow. Leaves are simple, elliptic, and have smooth margins. Alligator weed flowers during the warm months of the year and has whitish, papery ball-shaped flowers that grow on stalks. When alligator weed invades waterways, it can reduce water flow and quality by preventing light penetration and oxygenation of the water. It can also reduce water bird and fish activity and cause the death of fish and native plants. Alligator weed mats create a favorable habitat for breeding mosquitoes. Alligator weed is also difficult to control. Insects have been released for the biological control of alligator weed. The most successful and widely used is ''Agasicles hygrophila'' commonly called the alligator weed flea beetle; it has been released for biocontrol in Australia, China, Thailand, New Zealand, and the United States. ''Amynothrips andersoni'', the alligator weed thrips, and ''Vogtia malloi'', the alligator weed stem borer, have also been released in the United States. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Alternanthera philoxeroides」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
