Ecology, evolution and division of labour in social insects
Article Abstract:
N.R. Franks and C. Tofts' foraging-for-work algorithm fails to give a comprehensive account of the ecology and evolution of age-based division of labour in social insects. Several factors support the ecology and evolution of temporal polyethism in insects, such as colony-level and individual behavior patterns, nest structures, absence of a non-reproductive worker caste and worker sterility. A biological approach can provide an integrative understanding of the role of ecological variables and historical constraints in the organization of temporal division of labour in social insects.

Avoidance of superparasitism: a matter of learning?
Article Abstract:
Learning is a significant element in superparasitism behaviour, according to research using Plodia interpunctella as host species. Newly enclosed wasps given only parasitized hosts see the environment as containing few healthy hosts, and are therefore willing to superparasitize. They avoid superparasitism if given two healthy hosts, as they then assess healthy hosts to be be present in the environment. The Dufour's gland secretion injected into a host oviposition is detectable within three minutes.

Effects of adult mortality risks on parasitoid foraging tactics
Article Abstract:
Aphid parasitoids, Pauesia silvestris, change their foraging tactics according to host quality, host distribution and risk of mortality. Their egg-laying productivity is higher on pine aphids but there is more risk of aggression from ants with these aphids. Female parasitoids are safe on pine needles but not on bark. They will suffer the higher risk of spending time on bark where the aphid quality is higher than when using other types of aphid of lower quality.
