Thippali, Piper longum, is an important medicinal plant belonging to the family Piperaceae. An increase in ischolar_main knot nematode attack was observed in thippali growing plots in Kerala. But the nematode species has not been identified. The study was conducted to identify the ischolar_main knot nematode attacking thippali at Department of Agricultural Entomology, College of Horticulture, Kerala Agricultural University, Vellanikkara, Thrissur, Kerala. The study was undertaken by collecting soil and ischolar_main samples from thippali growing plots already infested with ischolar_main knot nematode. The species of ischolar_main knot nematodes were identified by the perineal pattern of white females collected from ischolar_main galls. The white females collected from the infested ischolar_mains were sent to Department of Nematology, Indian Agricultural Research Institute, New Delhi for species identification. The species of ischolar_main knot nematode attacking thippali was identified as Meloidogyne arenaria. This is the first report on attack of M. arenaria on thippali from India.

But the nematode species has not been identified. The study was conducted to identify the ischolar_main knot nematode attacking thippali at Department of Agricultural Entomology, College of Horticulture, Kerala Agricultural University, Vellanikkara, Thrissur, Kerala. The study was undertaken by collecting soil and ischolar_main samples from thippali growing plots already infested with ischolar_main knot nematode. The species of ischolar_main knot nematodes were identified by the perineal pattern of white females collected from ischolar_main galls.
