Abstract

The invention relates to tetraiodofluorescein, in particular to application of erythroseine B (namely tetraiodofluorescein) for killing adult mosquitoes of aedes albopictus. A photosensitive insecticide can be prepared by mixing the erythroseine B and 10 percent glucose water in a mass / volume ratio of 50 to 100 mg / ml. The photosensitive insecticide is impregnated or sprayed on carriers such as cotton fabrics or plants and is used as bait to be eaten by the adult mosquitoes of the aedes albopictus, and the adult mosquitoes, which are induced to eat the photosensitive insecticide, of the aedes albopictus are killed by lux illumination with the illuminance of 3*10<4> for 4 to 6 hours. The photosensitive insecticide is convenient to use, and a production process is simple and low in cost.

Description

Technical field [0001] The present invention relates to organic pigments, in particular to tetraiodofluorescein, especially to the use of tetraiodofluorescein B. Background technique [0002] Crimson B is derived from fluorescein iodination, its chemical name is tetraiodofluorescein B, molecular formula is C20H6I4Na2O5·H2O, molecular weight is 897.88, melting point is 303°C. Crimson B is a kind of red or reddish brown granules or powder, odorless, easily soluble in water, soluble in ethanol, propylene glycol and glycerin, insoluble in oil, heat resistance, alkali resistance, oxidation-reduction resistance, good resistance Bacteria and light fastness are poor, and it will precipitate when exposed to acid, and has poor hygroscopicity. Crimson B has good dyeability, especially for protein. According to its properties, it has stronger coloring power than other synthetic pigments in high-temperature baked foods and alkaline and neutral foods. In addition to being used as a food col...
