Adaptation and enslavement in endosymbiont-host associations
, 2004 The evolutionary persistence of symbiotic associations is a puzzle. Adaptation should eliminate cooperative traits if it is possible to enjoy the advantages of cooperation without reciprocating - a facet of cooperation known in game theory as the ...

Ecological Entomology, EarlyView.Using multiple infected and uninfected Drosophila sturtevanti lines, we investigated (i) the impact of Wolbachia on fecundity and (ii) its effects relative to antibiotic treatment. Based on over 1680 dissected ovaries, fecundity was similar between infected and uninfected flies.

Endosymbion microbials low abundance of Nilaparvata lugens (Stal) (Hemiptera: Delphacidae) from Indonesia rice production center based on metagenomic study using 16Sr RNA [PDF]
BIO Web of ConferencesInsects have a long history of association with endosymbiont microbes. There are several indications that endosymbiont microbes are associated with insects and participate in the degradation of organic and inorganic molecules.

Similar cost of Hamiltonella defensa in experimental and natural aphid‐endosymbiont associations
Ecology and Evolution, 2022 Endosymbiont‐conferred resistance to parasitoids is common in aphids, but comes at a cost to the host in the absence of parasitoids. In black bean aphids (Aphis fabae), costs in terms of reduced lifespan and lifetime reproduction were demonstrated by ...

Metagenomics for Bacteriology [PDF]
, 2015 The study of bacteria, or bacteriology, has gone through transformative waves since its inception in the 1600s. It all started by the visualization of bacteria using light microscopy by Antonie van Leeuwenhoek, when he first described “animalcules ...

Ecological Entomology, EarlyView.Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

Cascading effects of defensive endosymbionts [PDF]
Current Opinion in Insect Science, 2019 Defensive endosymbionts are now understood to be widespread among insects, targeting many different threats, including predators, parasites and disease. The effects on natural enemies can be significant, resulting in dramatic changes in the outcome of interactions between insects and their attackers.

Insect Molecular Biology, EarlyView.A small heat‐shock protein (HSP16) previously reported as insect‐derived in Bemisia tabaci actually originates from a fungal species of the genus Wallemia. BLAST, genome survey and phylogenetic analyses support the fungal origin and clarify persistent misattribution in the literature.

Changes in Aphid Host Plant Diet Influence the Small-RNA Expression Profiles of Its Obligate Nutritional Symbiont, Buchnera. [PDF]
, 2019 Plants are a difficult food resource to use, and herbivorous insects have evolved a variety of mechanisms that allow them to fully exploit this poor nutritional resource. One such mechanism is the maintenance of bacterial symbionts that aid in host plant
