Onion Thrips
註釋"The onion thrips, Thrips tabaci Lindeman, is the most destructive insect pest of onions in Washington State. This publication looks at how Thrips can damage onion plants, cause the production of smaller onion bulbs, and result in reduced crop yields. The onion thrips is also an important vector for the iris yellow spot virus (IYSV). IYSV is a tospovirus that causes iris yellow spot disease. This disease has caused significant economic losses involving both onion seed and bulb crops produced in Washington. Cultural, biological, and chemical methods are available to control onion thrips. Usually a combination of these methods is best. Controlling thrips also reduces the number of thrips functioning as a virus vector, thus reducing the incidence of iris yellow spot disease."--Abstract.
