Pathogenicity of on the Ornamental Plants and in Brazil.

has recently been reported in association with seeds of forage grasses and rice in Brazil and senescent strawberry plants, in the United States. This nematode is likely a mycophagous species; however, so far, its pathogenicity potential to plants is unclear. This study aimed to verify the pathogenicity of to two species of ornamental plants. The experiments were conducted by inoculating onto Bird's-Nest Fern () and Oriental Lily () leaves, using two inoculation methods (with and without injury). After 40 days of inoculation (DAI) in Bird's-Nest Fern and 5, 10, 20 and 40 DAI in Oriental Lily, the pathogenicity and the host efficiency were evaluated by symptoms observation and by severity, final nematode population and reproductive factor (RF), respectively. Additionally, a histopathological study was performed by inoculating onto Bird's-Nest Fern for observing anatomical alterations. was able to cause local necrotic lesions on both Bird's-Nest Fern and Oriental Lily leaves. However, the presence of injury was essential to enable to penetrate and cause those symptoms in both plant species. Also, the total population of decreased drastically over time and RF was <1, which characterized these species as poor-host or resistant plants. penetrated into the foliar tissue and induced a total destruction of the mesophyll and collapse of the cells, with the formation of large intercellular spaces. It is concluded that is an opportunistic pathogen as injury was required to induce symptoms in Bird's-Nest Fern and Oriental Lily.
