Symbiosis and Insect Diversification: an Ancient Symbiont of Sap-Feeding Insects from the Bacterial Phylum Bacteroidetes
It is shown that the large group of related insects including cicadas, leafhoppers, treehopper, spittlebugs, and planthoppers host a distinct clade of bacterial symbionts, belonging to the phylum Bacteroidetes. Expand
Immunity and other defenses in pea aphids, Acyrthosiphon pisum
It is suggested that several aspects of the aphid life style, such as their association with microbial symbionts, could facilitate survival without strong immune protection, and the traditional view of insect immunity may not be as broadly applicable as once thought. Expand
The Evolution of Agriculture in Insects
This work has shown that insect farmers are remarkably similar, suggesting convergent evolution, and that these insect farmers manage, in addition to the primary cultivars, an array of “auxiliary” microbes providing disease suppression... Expand
Genome Sequence of the Pea Aphid Acyrthosiphon pisum
The genome of the pea aphid shows remarkable levels of gene duplication and equally remarkable gene absences that shed light on aspects of aphid biology, most especially its symbiosis with Buchnera.
The Genome Sequence of the Leaf-Cutter Ant Atta cephalotes Reveals Insights into Its Obligate Symbiotic Lifestyle
Following recent reports of genome sequences from other insects that engage in symbioses with beneficial microbes, the A. cephalotes genome provides new insights into the symbiotic lifestyle of this ant and advances the understanding of host–microbe symbioss. Expand
Non-immunological defense in an evolutionary framework.
Findings from genome annotation and expression studies are discussed to show how immune system-based and non-immunological defenses interact and their importance for future studies of host-parasite coevolution is emphasized. Expand
Animal Behavior and the Microbiome
Research is revealing surprising roles for microbiomes in shaping behaviors across many animal taxa, shedding light on how behaviors from diet to social interactions affect the composition of host-associated microbial communities. Expand
Specificity in the symbiotic association between fungus-growing ants and protective Pseudonocardia bacteria
Fungus-growing ants (tribe Attini) engage in a mutualism with a fungus that serves as the ants' primary food source, but successful fungus cultivation is threatened by microfungal parasites (genusExpand
Ancient Host–Pathogen Associations Maintained by Specificity of Chemotaxis and Antibiosis
It is shown that parasitic fungal species in the genus Escovopsis, which attack and consume the fungi cultivated by fungus-growing ants, are attracted to their hosts via chemotaxis, thereby constraining long-term dynamics of host–parasite coevolution within this ancient association. Expand
Discovery of Paratelenomus saccharalis (Dodd) (Hymenoptera: Platygastridae), an Egg Parasitoid of Megacopta cribraria F. (Hemiptera: Plataspidae) in its Expanded North American Range
The plataspid quickly spread from the 9 northeastern Georgia counties in which it was initially confi rmed into 383 additional counties in Alabama, Florida, Georgia, Mississippi, North Carolina, South Carolina, Tennessee, and Virginia by the end of 2012 and has now been confiRmed in 4 additional states – Delaware, Kentucky, Louisiana, and Maryland – and the District of Columbia.
