Abstract
The present study was conducted in order to investigate the effect of pre-or post-irradiation treatment with visible light on UV-induced killing, using the first instar larvae from strains of Cambodge and5mAas materials.
1. The duration and the intensity of subsequent illumination with visible light necessary for obtaining saturation in photoreversing effect were 120min and 500lux, respectively.
2. The dose response curve for UV-induce killing without visible light illumination was sigmoid indicating that killing was multi-hit in character. The D37values forCambodgeand 5mA were 2.05×104and 5.89×104ergs/mm2, respectively.
3. By the post-treatment with visible light, UVinduced killing forCambodgeand5mA could be reversed up to 50% and 33%, respectively.
4. The killing action of UV was also reversed by the pre-irradiation treatment with visible light.
