How Common are Wolbachia and Other Bacteria in Insects?
New research on bacterial endosymbionts in insects suggests that such bacteria may infect a wide variety of insect species but a low proportion of individuals within those species.
Gut Microbes Can Help Insects Beat Pesticides
Insects have evolved a variety of mechanisms to try to overcome the effects of insecticides—including, in some cases, help from the bacteria and other microbes living in insects' guts. A growing number of studies indicate a link between symbiotic microbes and insecticide resistance in a diverse range of insects.
Cicadas Race to Catch Up With Their Evolving Endosymbionts
In cicadas, a world of microbes has evolved to provide them nutrients. Researchers at the University of Montana have discovered that a cicada bacterial endosymbiont, Hodgkinia cicadicola, has split into at least two dozen lineages within cicada cells, in an apparent case of nonadaptive evolution.
Bacteria Can Aid Aphids Against Predation and Parasitism
By Meredith Swett Walker Aphids are among the most destructive plant pests. The small, sap-sucking insects are the bane of many a farmer and gardener. Typically soft bodied and without […]
