据Koshy等(1977)报道:1949年喀拉拉邦胡椒幼树自生根疣线虫广泛蔓延。Koshy等曾筛选出用于胡椒支柱的一些树种,发现嘉榄对自生根疣线虫有免疫力。Koshy等(1979)筛选出了七个抗自生根疣线虫的胡椒栽培品种,并发现杂种Panniyur Ⅰ极易感病。虽然许多研究人员都报道过线虫的寄主。但这些线虫对胡椒的致病作用还没有进行过研究。 According to Koshy et al. (1977), in 1949, the root bryophyte nematodes of pepper young trees in Kerala widely spread. Koshy, who had screened some of the tree species used for pepper pillars, found that the gilts are resistant to the genus Brachyura. Koshy et al. (1979) screened seven pepper cultivars resistant to the genus Myrothecium and found that the hybrid Panniyur I was extremely susceptible. Although many researchers have reported nematodes hosts. However, the pathogenic effects of these nematodes on pepper have not been studied.
