Abstract: In order to realize the interspecific correlation of Hylobitelus xiaoi occurrence and understory nonhost plants of Pinus elliottii Forests, the interspecific correlation of Hylobitelus xiaoi and understory nonhost plants in Pinus elliotii forests in Jiangxi province was analyzed in this paper by using 2×2 table, variance analysis, χ2test, association coefficient, Ochiai index, Dice index and Cramer index were used. The results showed that the interspecific correlation of Hylobitelus xiaoi and understory nonhost plants was not obvious. It indicated that the occurrences of Hylobitelus xiaoi was not directly related to the these nonhost plants.
