¹⁵N-marked aphids for predation studies under field conditions
Entomologia Experimentalis et Applicata 94 (3), 319-323
Abstract: Individuals ofSitobion avenae (F.) (Homoptera: Aphididae) were marked with the stable isotope ¹⁵N through feeding on cereal seedlings which were immersed in a¹⁵N-enriched nutrient solution. Increased ¹⁵N-contents were obtained in all aphids with no detrimental effect on survival and fertility. When ¹⁵N-marked aphids were transferred to non ¹⁵N-enriched seedlings, after a short initial decreasing phase, ¹⁵N-contents remained nearly constant in time. A content of 10% ¹⁵N in the nutrient solution of the seedlings was sufficient for marking the aphids.
