Abstract
Pea aphids (Acyrthosiphon pisum (Harris)) were marked with rubidium by rearing them on broad bean plants (Vicia faba L.) maintained in nutrient solutions that contained rubidium chloride. Rb+ was readily detected by atomic absorption spectrophotometry in groups of aphids, and it varied in concentration with the concentration in the plant. A technique was developed for the preparation and analysis of single aphids marked with Rb+. More than 77% of the Rb+ in marked adult aphids was lost within 2 days of leaving the source plant, but detectable quantities remained for 4 days.Keywords
