Nutritional symbionts play a major role in the ecology and evolution of insects. The recent
accumulation of knowledge on the identity, function, genomics, and phylogenetic …

Herbivory, defined as feeding on live plant tissues, is characteristic of highly successful and
diverse groups of insects and represents an evolutionarily derived mode of feeding. Plants …

Background Symbiotic bacteria affect insect physiology and ecology. They may also mediate
insecticide resistance within their hosts and thereby impact pest and vector control practices …

1. Bacterial symbionts play a prominent role in insect nutritional ecology by aiding in
digestion of food or providing nutrients that are limited or lacking in the diet. Thereby …

Insect heritable symbionts have proven to be ubiquitous, based on molecular screening of
various insect lineages. Recently, molecular and experimental approaches have yielded an …

Summary 1 Many insects derive nutritional advantage from persistent associations with
microorganisms that variously synthesize essential nutrients or digest and detoxify ingested …

Aphids engage in symbiotic associations with a diverse assemblage of heritable bacteria. In
addition to their obligate nutrient-provisioning symbiont, Buchnera aphidicola, aphids may …

Symbiotic microbes have become increasingly recognized to mediate interactions between
natural enemies and their hosts. The ecologies of these symbioses, however, are poorly …

Psyllids, whiteflies, aphids, and mealybugs are members of the suborder Sternorrhyncha
and share a common property, namely the utilization of plant sap as their food source. Each …

In the Origin of Species, Darwin struggled with how continuous changes within a species
lead to the emergence of discrete species. Molecular analyses have since identified nuclear …
