Biological control is widely successful at controlling pests, but effective biocontrol agents are
now more difficult to import from countries of origin due to more restrictive international trade …

Understanding the coevolution of hosts and parasites is a long‐standing goal of
evolutionary biology. There is a well‐developed theoretical framework to describe the …

Aphidius gifuensis is a parasitoid wasp and primary endoparasitoid enemy of the peach
potato aphid, Myzus persicae. Artificially reared, captive wasps of this species have been …

The first Parasite Microbiome Project (PMP) Workshop (January 9–14, 2019, Clearwater,
Florida, United States) hosted researchers from across continents and disciplines to lay the …

Parasite‐mediated selection can rapidly drive up resistance levels in host populations, but
fixation of resistance traits may be prevented by costs of resistance. Black bean aphids …

Facultative, heritable endosymbionts are found at intermediate prevalence within most
insect species, playing frequent roles in their hosts' defence against environmental …

Insect host–parasitoid interactions abound in nature and are characterized by a high degree
of host specialization. In addition to their behavioral and immune defenses, many host …

Heritable, facultative symbionts are common in arthropods, often functioning in host defence.
Despite moderately reduced genomes, facultative symbionts retain evolutionary potential …

During oviposition, ectoparasitoid wasps not only inject their eggs but also a complex
mixture of proteins and peptides (venom) in order to regulate the host physiology to benefit …
