A phototoxic insecticidal composition includes at least one photoactive dye, an attractant bait composition and/or feeding stimulant and at least one adjuvant, whereby the adjuvant interacts with the photoactive dye and insect membranes to alter the toxicity of the composition once ingested by the insect. More specifically, the composition is directed to killing the Mexican fruit fly.

Phototoxic insecticidal composition and method for controlling insect

A composition and method for eradicating or suppressing a population of Mediterranean fruit flies or oriental fruit flies which introduces substantially minimal safety risks to humans, agriculture and nontargeted living creatures includes: providing an insecticide composition which includes at least one photoactive dye which is preferably a mixture of Phloxine B and uranine; causing the composition to be ingested by the targeted fruit fly population by spraying or providing the insecticide at a location where the fruit flies feed; and whereby ingestion of the photoactive dye component of the composition by a Mediterranean fruit fly or oriental fruit fly causes a toxic quantity of photons to penetrate within the body of the fly.

Pesticide composition and method for controlling the oriental fruit fly

A phototoxic insecticidal composition includes at least one photoactive dye present in the amount of between 0.025%-4.0% of the composition, an attractant compound and/or feeding stimulant and at least one adjuvant, whereby the adjuvant interacts with the photoactive dye and insect membranes to alter the toxicity of the composition once ingested by the insect.

Dyes which, in the presence of molecular oxygen, promote the formation of cytotoxic oxygen are used to combat internal parasites in warm blooded animals. Internal parasites having the dye incorporated therein are exposed to electromagnetic radiation to initiate one or more lethal oxidative reactions. The photosensitized parasites may be in the infective stage thereby breaking the life cycle. This reduces or prevents reinfection and the need for traditional anthelmintics.

Combatting internal parasites in warm blooded animals

Water insoluble, photodynamic insecticidal compositions comprising the free acids of erythrosin B, phloxin B, rose bengal, octabromofluorescein or fluorescein or the aluminum lakes thereof, optionally including a dispersant, aqueous dispersions of the same and a method of combatting adult insects and insect larvae by use of the same.

Phototoxic insecticidal compositions and method of use thereof

Synergistic insecticidal compositions are mixtures of at least one insecticidally active water-soluble xanthene dye chosen from amongst erythrosine and Rose Bengal in admixture with the essentially non-insecticidally active and synergistically-effective fluorescein sodium.
