 en Short Communication - Efficiency of Rubidium Marking in Aedes albopictus (Diptera: Culicidae): Preliminary Evaluation on Persistence of Egg Labeling, Survival, and Fecundity of Marked Female
Rafael Maciel-de-Freitas; Jaylei Monteiro Gonçalves & Ricardo Lourenço-de-Oliveira

Abstract

Rubidium chloride (RbCl) has been used for the study of vector biology and behavior, although the efficacy of marking, egg production, and survivorship of marked females have been poorly studied. Four concentrations of RbCl were tested, among which 0.025 M was the best for marking Aedes albopictus: more than 80% of egg batches of females fed once with blood containing RbCl were marked; Rb-marked egg batches, interspersed with non marked ones were recovered until 61 days after a blood meal containing RbCl followed by non marked meals; RbCl was essentially detected in the abdomen of marked females, whose egg production and survivorship did not differ from non marked ones, at least in the three weeks following the Rb-marked blood meal.
