The different species of the genus have different preference on feeding host and reproduction, and the population movement are highly impacted by environmental factors such as temperature. Under the influence of global warming, the average atmosphere temperature each month in the Maioli Dahu region have been continuing raising since 2012. In 2017, the new record root lesion species P. vulnus was discovered in 3 fields in the region, and it is likely a nematode majority population substitution due to the raising environment temperature. Although lesion symptoms have been observed on the strawberry root that have been invaded by the lesion nematodes, the actual correlation of the nematode population density and the host growth, the impact yield or even the management options were never examined on the popular varieties grown in Taiwan. The P. vulnus epidemic poses a great potential risk to the 10 billion strawberry production industry. Therefore, this project aims to study the growth and economy impact on strawberry after P. vulnus invasion, and evaluate potential non-chemical management options for the IPM control of the issue. The outcome of this research would provide valuable information for nematode management strategy and put the growers worrisome at ease.草莓根腐線蟲溫度strawberryroot lesion nematodetemperature
