title: Use of a Stilbene Brightener, Tinopal LPW, as a Radiation Protectant for Steinernema carpocapsae.
abstract: A stilbene fluorescent brightener, Tinopal LPW, was used as an ultraviolet (UV) protectant for the entomopathogenic nematode Steinernema carpocapsae (All strain). Irradiation of an aqueous suspension of nematodes produced a LC in 15.7 minutes under a sunlamp and in 31.7 minutes in direct sunlight. Irradiation by both sunlamp and sunlight of a suspension of nematodes in Tinopal LPW did not reduce their biological activity as measured by their ability to parasitize wax moth larvae after exposure of 8 hours and 4 hours, respectively. Tinopal LPW appeared promising as a radiation protectant.
