Diverse insects host specific microbial symbionts that play important roles for their growth,
survival, and reproduction. They often develop specialized symbiotic organs for harboring …

Timing the acquisition of a beneficial microbe relative to the evolutionary history of its host
can shed light on the adaptive impact of a partnership. Here, we investigated the onset and …

Insects typically acquire their beneficial microbes early in development. Endosymbionts
housed intracellularly are commonly integrated during oogenesis or embryogenesis …

Obligate symbioses with bacteria allow insects to feed on otherwise unsuitable diets. Some
symbionts have extremely reduced genomes and have lost many genes considered to be …

Numerous adaptations are gained in light of a symbiotic lifestyle. Here, we investigated the
obligate partnership between tortoise leaf beetles (Chrysomelidae: Cassidinae) and their …

Abstract Leaf beetles (Coleoptera: Chrysomelidae) constitute one of the most species-rich
insect families, and live exclusively on leaves or other plant parts. Early histological works …

Beetles are hosts to a remarkable diversity of bacterial symbionts. In this article, we review
the role of these partnerships in promoting beetle fitness following a surge of recent studies …

While genome erosion is extensively studied in intracellular symbionts, the metabolic
implications of reductive evolution in microbes subsisting extracellularly remain poorly …

Many insects feeding on nutritionally challenging diets like plant sap, leaves, or wood
engage in ancient associations with bacterial symbionts that supplement limiting nutrients or …

ABSTRACT A pervasive pest of stored leguminous products, the bean beetle
Callosobruchus maculatus (Coleoptera: Chrysomelidae) associates with a simple bacterial …
