The evolution of a mutualism requires reciprocal interactions whereby one species provides
a service that the other species cannot perform or performs less efficiently. Services …

The ambrosia beetle–fungus farming symbiosis is more heterogeneous than previously
thought. There is not one but many ambrosia symbioses. Beetle-fungus specificity is clade …

We review the morphology, larval feeding habits, reproductive behavior, and social behavior
of Scolytinae and Platypodinae. Their morphology and behavior are adaptations to a …

Scolytine beetles show enormous diversity in their mating behaviors, host plant
associations, chemical and acoustic signaling, symbiotic relationships, and other critical …

Employing the clear, student-friendly style that made previous editions so popular, Insect
Physiology and Biochemistry, Fourth Edition presents an engaging and authoritative guide …

Obligate eusociality with distinct caste phenotypes has evolved from strictly monogamous
sub-social ancestors in ants, some bees, some wasps and some termites. This implies that …

Model organisms are often used in biological, medical and environmental research. Among
insects, Drosophila melanogaster, Galleria mellonella, Apis mellifera, Bombyx mori …

How can the stunning diversity of social systems and behaviours seen in nature be
explained? Drawing on social evolution theory, experimental evidence and studies …

Ectosymbioses among bark beetles (Curculionidae, Scolytinae) and fungi (primarily
ophiostomatoid Ascomycetes) are widespread and diverse. Associations range from …

The evolution of cooperative breeding has been traditionally attributed to the effect of kin
selection. While there is increasing empirical evidence that direct fitness benefits are …
