With millions of insect species already identified, and studies revealing more about them every day, Entomology Abstracts provides the only practical means for researchers whose work is affected by these findings to keep up with the field. All recent research reports of direct relevance to entomology are assembled here, with coverage including insects, arachnids, myriapods, onychophorans, and terrestrial isopods. From the most ancient fossilized forms to newly-discovered species, Entomology Abstracts gathers and summarizes all the latest information on millions of insects and insect-like species, for truly global coverage of the field.

Abstract
Although the evolution of large-scale dispersal has received considerable
attention, we know very little about how natural selection influences
foraging behaviours in herbivorous insects. Host-selection behaviours
and within-habitat movements jointly determine foraging behaviours,
since host selection affects the allocation of time spent on a
particular host versus moving between these hosts. However, host
selection is generally a labile trait, whose expression is influenced
by the physiological state of the forager and hence, by characteristics
of the habitat. We discuss how the quantitative genetic concepts
can be used to study the evolution of such labile behaviours.
Since host responses depend on the physiological state of the
forager, it is argued that the state of the forager must be explicitly
considered when estimating the additive genetic basis of host-selection
behaviours. The lability of foraging behaviours increases the
difficulty of measuring the fitness consequence of variation in
the foraging phenotype in specific habitats. Therefore, it may
be difficult to rely exclusively on quantitative genetic methods
to test hypotheses about adaptive change in foraging behaviours
across different habitats. We provide a novel approach based on
optimality modelling to calculate the fitness consequence of variation
in the foraging phenotype across different habitats. This method,
in conjunction with quantitative genetics, can be used to test
hypotheses concerning the evolution of foraging behaviours. |
