Fluorometric assessments of Simuliidae gut contents can measure algal ingestion, but pigment extraction methods are variable. Total pigment concentration was not significantly different across three tested methods. An organic solvent extraction method using intact larvae provides efficient, repeatable quantifications of larval diets, is comparably more applicable to all life stages, and will enable examinations of relationships between larval feeding and insecticide effectiveness.
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
