Abstract
Photosensitizing Effect of Rose Bengal, Methylene Blue and Rhodamine on Cotton Leaf worm, Spodoptera littoralis Larvae
Highlights
Spodoptera littoralis is one of the most serious agricultural pests
Ishaaya and Klein (1990) The intensive use of broad-spectrum insecticides against S. littoralis has led to the development of resistance and undesirable effect (Wu et al.,2007) Photosensitivity insecticide has attracted increasing attention as a new type of highly efficient and environment-friendly pesticide (Ben Amor and Jori 2000)
The main groups of photodynamic sensitizers that have been used as photoinsecticides are the thiophenes, furanocoumarins, xanthenes, porphyrins, phenol-thiazines, thiophene, acridines, and quinines (Ben Amor and Jori, 2000). phloxin B and Xanthene dyes (Ben Amor and Jori, 2000, Schroder et al, 2001) xanthene (Sakurai and Heitz,1982; Fondren and Heitz, 1978). porphyrin- compounds (Lukšiené et al, 2007) oxygen species (ROS) such as singlet oxygen has been identified as one of the major species responsible for biological damage caused by photosensitization (Weishaput, Goomer, & Dougherty, 1976)
