The diversity and fitness effects of infection with facultative endosymbionts in the grain aphid, Sitobion avenae.

Oecologia - 1 Nov 2013

Łukasik Piotr, Dawid Maciej A, Ferrari Julia, Godfray H Charles J

Abstract excerpt

Mutualisms with facultative, non-essential heritable microorganisms influence the biology of many insects, and they can have major effects on insect host fitness in certain situations. One of the best-known examples is found in aphids where the facultative endosymbiotic bacterium Hamiltonella defensa confers protection against hymenopterous parasitoids. This symbiont is widely distributed in aphids and related...
