Transmission of potato virus Y by cereal aphids
Potato Research, 1985 The cereal aphidRhopalosiphum padi transmitted PVYO and PVYN from and to both tobacco and potato. However, it transmitted much less frequently thanMyzus persicae, even when aphids making single probes were compared.R. padi andM. persicae retained PVY for a similar duration. Both alatae and apterae ofR.

Insect Science, EarlyView.The mutualism between Tapinoma ibericum ants and Aphis gossypii disrupts the biological control exerted by Aphidius colemani in greenhouse peppers. Ant exclusion increased parasitism and the presence of most natural enemies, although Aphidoletes aphidimyza was more abundant with ants.

Reduced fertilization regimes could boost biocontrol service without reducing crop yield
Insect Science, EarlyView.Fertilization level influences pest control effectiveness in tomato crops. High fertilization increases plant growth and aphid density but reduces the performance of the parasitoid Aphidius ervi. In contrast, the predator Adalia bipunctata maintains consistent aphid suppression regardless of fertilization regime.

Report of Coccinella magnopunctata (Col.: Coccinellidae) from Iran [PDF]
نامه انجمن حشرهشناسی ایران, 2011 In a faunistic survey of aphids and their aphidophagous predators in cereal fields of Mashhad and vicinity, during 2006-2008, several coccinellid species were collected and determined.

Distribution and diversity of wheat aphid parasitoids (Hymenoptera: Braconidae: Aphidiinae) in Iran
European Journal of Entomology, 2008 Eleven species of parasitoids were found to attack 7 species of wheat aphids in Iran. The Simpson's Index of diversity (D) used to compare the aphidiine diversity in various cereal crop systems in geographically different regions of Iran ranged from 0 ...

Aphid and endosymbiont sensitivity to heatwaves is misaligned across life stages
Insect Science, EarlyView.Aphids depend on the obligate symbiont Buchnera aphidicola, which may constrain thermal tolerance. Using a factorial heatwave experiment, we exposed nymphs and adults to moderate or extreme temperatures and measured fitness and symbiont responses.

BIOLOGY OF APHIDIUS RHOPALOSIPHI, A PARASITOID OF CEREAL APHIDS
Entomologia Experimentalis et Applicata, 1983 Aphidius rhopalosiphi produced 212 offspring on average but in one case 509 deposited eggs were found. Superparasitization occurred but the frequency distribution of parasitoid larvae in aphids differed significantly from random, indicating a certain degree of host discrimination. Average life span of adults was 13.1 days and sex ratio was 1: 1.

The dual crisis: Climate change simultaneously drives pollinator decline and pest outbreaks
Agricultural and Forest Entomology, EarlyView.Climate change acts as an asymmetric ecological filter, favouring r‐selected pest traits (rapid reproduction, generalism) while disadvantaging K‐selected pollinators. For every 1°C of warming, bee species richness declines ~25% since the 1990s, while pest‐induced crop losses increase by 10%–25%. A network‐centric approach integrating climate‐responsive

First records of Charipinae (Hymenoptera, Cynipoidea, Figitidae) aphid hyperparasitoids from Malta [PDF]
, 2015 Charipinae material has been collected from different localities in Malta. Three species have been identified: Alloxysta citripes, Alloxysta pilipennis and Phaenoglyphis villosa in association with two aphids and one parasitoid species.
