The di-symbiotic systems in the aphids Sipha maydis and Peryphillus lyropictus provide a contrasting picture of recent co-obligate nutritional endosymbiosis in aphids

This study compares the metabolic and anatomical integration of two recently acquired nutritional symbionts in two aphid species, revealing distinct coevolutionary processes.

Assessing the optimal frequency of early parasitoid releases in an apple orchard to control Dysaphis plantaginea: a proof of concept study

This study tests early parasitoid releases in apple orchards to control Dysaphis plantaginea, finding that parasitoid releases at either weekly or biweekly intervals can provide aphid control but require calibration.

Ubiquity of the Symbiont Serratia symbiotica in the Aphid Natural Environment: Distribution, Diversity and Evolution at a Multitrophic Level

This study investigates the distribution, diversity, and evolution of the aphid symbiont Serratia symbiotica across multiple trophic levels in natural environments.

Impact of the pear psyllid Cacopsylla pyri host instar on the behavior and fitness of the parasitoid Trechnites insidious

This study evaluates how different host instars of Cacopsylla pyri affect the behavior and fitness of the parasitoid Trechnites insidiosus, finding that third and fourth instars are most suitable for oviposition and progeny development.

Phenotypic plasticity explains apparent reverse evolution of fat synthesis in parasitoid insects

The paper shows that apparent reverse evolution of fat synthesis in parasitoid insects is due to phenotypic plasticity, not actual genetic regain, and demonstrates its evolutionary stability through simulations.

Trans-generational effects on diapause and life-history-traits of an aphid parasitoid

This study examines transgenerational effects on diapause and life-history traits in two strains of Aphidius ervi under controlled environmental conditions, finding increased diapause levels in wild strains and transgenerational plasticity effects on development and morphology.

New Insights into the Nature of Symbiotic Associations in Aphids: Initial Steps Involved in Aphid Gut Infection by Serratia symbiotica Bacteria

This study investigates the infection dynamics of cultivable Serratia symbiotica bacteria in aphids, revealing gut colonization, fitness costs, and environmental transmission.
