茎线虫Ditylenchus dipsaci是许多植物的一种毁灭性害虫。虽然这种线虫在这些寄主范围内已发现有许多小种或株系,但对这些小种还缺乏明确的描述,并且有些小种似乎还能适应新的寄主。洋葱是蔬菜作物中被害最严重最广泛的一种,但萝卜、欧洲防风、蚕豆、豌豆和大黄也被侵染。至少这些作物中的一些被侵染草莓、燕麦和其它作物的一个小种所侵染。 Ditylenchus dipsaci is a devastating pest on many plants. Although such nematodes have been found to have many races or strains within these host ranges, there is a lack of a clear description of these races, and some races appear to be able to adapt to new hosts. Onions are the most widespread and widespread form of vegetable crops, but radish, European wind, broad beans, peas and rhubarb are also infested. At least some of these crops are infested with a raccoon that infects strawberries, oats and other crops.
