On the assessment of prey suitability in aphidophagous Coccinellidae [PDF]
European Journal of Entomology, 2005 Empirical protocols for assessing the suitability of prey for aphidophagous coccinellids are examined and a modified scheme of categorization is presented. It is argued that prey suitability should be assessed independently for larval development and adult reproduction because of potentially divergent nutritional requirements between these life stages.
