Moderately decreasing fertilizer in fields does not reduce populations of cereal aphids but maximizes fitness of parasitoids. [PDF]

Sci Rep, 2021
Examination of the tradeoff between the extent of decreasing nitrogen input and pest suppression is crucial for maintaining the balance between essential yield and an efficient, sustainable pest control strategy.

Aphid parasitism alters induced plant responses allowing a hyperparasitoid to locate its hidden parasitoid host. [PDF]

New Phytol
Summary Plants typically host insect communities composed of multiple trophic levels that are intricately linked through interactions mediated by the shared food plant. Hyperparasitoids are top‐level carnivores in such systems, preying on parasitoid larvae developing inside herbivores. These hyperparasitoids can dramatically reduce the effectiveness of

Data from: Are generalist Aphidiinae (Hym. Braconidae) mostly cryptic species complexes?

Systematic Entomology, 2015
Aphidiinae are mostly composed of specialist parasitoids and the few species described as generalist are suspected to be composed of cryptic specialists, almost indistinguishable based on morphological characteristics.

Dyscrituluseuropaeus sp. nov. (Hymenoptera, Braconidae, Aphidiinae): description of a new aphid parasitoid species with an identification key for species of the genus. [PDF]

Zookeys, 2023
The braconid genus Dyscritulus Hincks is a small member of the subfamily Aphidiinae, distributed in Europe and Central Asia. All its species are highly specialized parasitoids of aphids of the genera Drepanosiphum Koch and, probably, Periphyllus van der ...

Defensive symbiosis in the wild: Seasonal dynamics of parasitism risk and symbiont‐conferred resistance

Molecular Ecology, Volume 32, Issue 14, Page 4063-4077, July 2023., 2023
Abstract 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 (Aphis fabae) benefit from increased resistance to parasitoids when carrying the defensive bacterial endosymbiont Hamiltonella defensa.

Flower strips increase the control of rosy apple aphids after parasitoid releases in an apple orchard

Annals of Applied Biology, Volume 182, Issue 2, Page 245-256, March 2023., 2023
Flower strips in apple orchard alleways may improve the control of rosy apple aphids by mass released parasitoids. Abstract Mass releases of two parasitoid species, Aphidius matricariae and Ephedrus cerasicola, may provide an alternative measure to pesticides to control the rosy apple aphid Dysaphis plantaginea in organic apple orchards.

A Review of Aphid Parasitoids, with an Identification Key to the Genera of Economic Importance. [PDF]

Insects
Agriculture plays an essential role in meeting global food demand, and so effective pest control is crucial. Aphids (Hemiptera: Aphididae) are a significant problem for many crops worldwide, and cause crop losses.

Enigma moth parasitoid: a new Australian cyclostome genus and species, Ovaustra aurantia Tetley, Glatz & Fagan Jeffries, gen. et sp. nov. (Hymenoptera: Braconidae) from Kangaroo Island

Austral Entomology, Volume 61, Issue 4, Page 420-432, November 2022., 2022
Abstract Ovaustra aurantia Tetley, Glatz & Fagan‐Jeffries, gen. et sp. nov. (Mesostoinae) is described from Kangaroo Island. South Australia, Australia, and is a solitary, koinobiont, egg‐larval parasitoid of the enigma moth, Aenigmatinea glatzella Kristensen & Edwards, 2015, in the monotypic family Aenigmatineidae Kristensen & Edwards, 2015 ...
