Insects are by far the most diverse group of organisms on Earth; estimates of their current
diversity range as high as 30 million species (58). A large fraction of these species feed on …

The authors review a selection of key references to studies on the disperal and movement of
insect pests that have been published since the review by CG Johnson in 1969. The 3 main …

There are many different types of organisms in the world: they differ in size, physiology,
appearance, and life history. The challenge for evolutionary biology is to explain how such …

This outstanding work is the ultimate guide for the identification of Australia's butterflies.
Nearly 400 species–all those currently recognised from Australia, plus those from …

Unlike many insects, the caterpillars of the cabbage butterfly, Pieris rapae, are less
abundant on host plants that grow in large dense stands than on hosts that are scattered …

Seasons impose different selection pressures on organisms through contrasting
environmental conditions. How such seasonal evolutionary conflict is resolved in organisms …

The purpose of this study was to examine the effect of the spatial arrangement of host—plant
patches on local abundance of the cabbage butterfly (Piers rapae). By considering the …

1 Evolutionary pressure should select for efficient foraging strategies, within the constraints
of other selective forces. We assess the mechanisms underlying flower choice in the …

Larvae reared at low temperatures produce larger pupae and adults than those reared at
high temperatures, and pupal weight is linearly related to lifetime egg production; mean egg …

Publisher Summary Studies on population dynamics and host use of Pieridae cover a
number of taxa but are heavily biased toward Holarctic pest species and their close …
