Abstract Many photoactive dyes are relatively nontoxic to vertebrates despite their insecticidal properties. Several photoactive dyes known to be toxic to some groups of insects were evaluated at various concentrations for toxicity to American and migratory grasshoppers in laboratory and field studies. Rose bengal and phloxine B were effective at inducing mortality of grasshoppers when applied at 2 and 5% to bran bait, though erythrosin B and uranine were ineffective. Partial replacement of… 
Evaluation of phloxine B as a photoinsecticide on immature stages of the horn fly, Haematobia irritans (L.) (Diptera: Muscidae)
Results indicate that H. irritans larvae are very sensitive to this dye, which in turn seems a promising component for larvicide formulations to control horn flies.
Phloxine B Effect on Immature Stages of the Mediterranean Fruit Fly, Ceratitis capitata (Diptera: Tephritidae) (Wiedemann)
A laboratory bioassay was developed to determine both the chemical toxicity and the phototoxicity of the xanthene dye, phloxine B, to the immature stages of the Mediterranean fruit, giving rise to abnormal puparia and failed adult ecdysis, thus reinforcing the idea of pleiotropic effects of the dye.
Phloxine B effect on immature stages of the Mediterranean fruit fly, Ceratitis capitata (Diptera: Tephritidae) (Wiedemann).
A laboratory bioassay was developed to determine both the chemical toxicity and the phototoxicity of the xanthene dye, phloxine B, to the immature stages of the Mediterranean fruit fly, Certitis capitata, to find out which main tissues are affected first.
Development of a Toxic Bait for Control of Eastern Lubber Grasshopper (Orthoptera: Acrididae)
It is expected that wheat bran and corn oil bait would be most effective as protection for less preferred plants (tomato, pepper, eggplant, leek, parsley, fennel, daylily, lily of the Nile, and canna lily) because baits were readily consumed in the presence of these plants.
Ecotoxicity of xanthene dyes and a non-chlorinated bisphenol in soil.
Estimation of the bioaccumulation potential of a nonchlorinated bisphenol and an ionogenic xanthene dye to Eisenia andrei in field‐collected soils, in conjunction with predictive in silico profiling
In silico-based model predictions, structural and mechanistic profiling demonstrated the binding and reactivity potential of Phloxine B; this would not be accounted for using traditional bioaccumulation metrics, which are founded on passive-based diffusion mechanisms.
The discoloration of Eosin Y and Rose Bengal by indirect anodic oxidation was studied by employing boron doped diamond (BDD) and Pt electrodes. The effect of electrolyte, initial pH and applied
Xantenos y porfirinas, moléculas fotoactivables empleadas en el control de insectos plaga.
The photodynamic sensitizers Phloxine B and Hematoporphyrin IX were tested as photoinsecticides against pest flies and showed an important toxic effect during the larval dispersal period.
Buffer composition affects rose bengal dialysis rate through cellulose membrane
The results show that buffer composition does not influence the fluorescent properties of RB, however, the presence of additional ions causes a change in diffusion rate that is most probably linked to the size of RB aggregates.


Activity of Xanthene Dyes Against Black Cutworm Larvae
Mortality in 5th–6th instars as a function of dietary concentration of rose bengal and illumination time showed that LT50 values decreased with increasing dietary concentration, and relative toxicity of rosebengal was described by means of a pseudo 2nd-order rate constant of photooxidation.
Photodynamic Action in Insects. 1. Levels of Mortality in Dye-Fed Light-Exposed House Flies
The effectiveness of 6 fluorescent dyes was determined in the photodynamic killing of Musca domestica L. under conditions of darkness, and artificial and natural light. Rose bengal, erythrosin B ,
Light-Dependent Latent Toxicity of Rose Bengal to Culex pipiens quinquefasciatus
Exposure of larval Culex pipiens quinquefasciatus Say to 1–30 ppm aqueous solutions of the xanthene dye rose bengal in the presence of visible light caused significant acute mortality and the latent mortality increased the total toxicity of rose bENGal by ca.
Acceptance of wheat bran bait by species of rangeland grasshoppers.
The experimental design is described for a 8500-ha pilot management test of wheat bran bait containing insecticide, Nosema locustae Canning, or both, for control of a complex of rangeland
A model for predicting efficacy of carbaryl bait for control of rangeland grasshoppers.
Three dosages of wheat bran bait containing 1.96% carbaryl by weight were applied by aircraft to infested rangeland to suggest that bait treatments could be made much more economical by increasing the efficiency of individual flakes and by reducing the rate of application.
