Details on Thrips palmi in Korea Republic
In a scientific paper on spatial distribution and sampling methods, some details are given on the situation of Thrips palmi (EPPO A1 quarantine pest) in Korea Republic. T. palmi was first found in 1993 in protected cultivation of capsicum. Within a few years, it has become a serious pest of vegetable and ornamental crops in the southern coastal areas of Korea, including Cheju island. For example, it is reported that in 1994 an outbreak of T. palmi on potatoes grown in Cheju island caused yield losses of 30 %. The geographical distribution of T. palmi is expanding towards the north, due to its wide host range and lack of effective control measures.
