Insects comprise the largest species composition in the entire animal kingdom and possess
a vast undiscovered genetic diversity and gene pool that can be better explored using …

We here attempt to show, using three broad insect groups–Lepidoptera (mainly leaf-
chewing larval herbivores and nectar-sucking adults), parasitic Hymenoptera (mainly …

Many plant‐feeding insect species considered to be polyphagous are in fact composed of
genetically differentiated sympatric populations that use different hosts and between which …

Genetic structuring of populations reflects the interaction of genetic drift, mutation, migration
and selection, with influences from life history. Aphids are interesting in this regard as they …

This study investigated the relationship between the essential amino acid requirement of the
aphid Aphis fabae Scop. and the phloem sap amino acid composition of its host plants. The …

It is well established that asexually reproducing viruses and prokaryotes mutate rapidly. In
contrast, the eukaryotic clone is often still treated as if it is genetically homogeneous within …

1. Host‐specialised races of plant‐feeding insects are particularly informative models in the
study of ecological speciation, that is, the evolution of reproductive isolation through …

Parasite–host cospeciation has received much attention as an important mechanism in the
diversification of phytophagous insects. However, studies have shown that for certain taxa, it …

Abstract In Chile, the aphid Sitobion avenae is of recent introduction, lives on cultivated and
wild Poaceae, and is thought to reproduce by permanent parthenogenesis. In order to study …

Populations of clonal organisms are often represented as being evolutionary inert with
persistent genetic fidelity. The advent of molecular methods and the corresponding …
