Aphid parasitoids (Braconidae, Aphidiinae) of Vietnam: new records and description of 12 new species
European Journal of TaxonomyBased on a collection made during the period 1999–2009, we record 27 aphid parasitoid species from Vietnam, of which 12 are new to the Vietnamese fauna (Aphidius autriquei Starý, 1985; Aphidius ervi Haliday, 1834; Aphidius urticae Haliday, 1834 ...

Aphid symbionts and endogenous resistance traits mediate competition between rival parasitoids. [PDF]
PLoS ONE, 2017 Insects use endogenous mechanisms and infection with protective symbionts to thwart attacks from natural enemies. Defenses that target specific enemies, however, potentially mediate competition between rivals and thereby impact community composition ...

Egyptian Journal of Biological Pest Control, 2020 Three parasitoid species viz. Aphelinus asychis Walker (Hymenoptera: Aphelinidae), Aphidius ervi (Haliday) (Hymenoptera: Braconidae) and Diaeretiella rapae (McIntosh) (Hymenoptera: Braconidae) parasitizing the aphid species Myzus persicae (Sulzer ...

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 ...

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.

Improvement in the cold storage of Aphidius ervi (Hymenoptera: Aphidiinae)
EUROPEAN JOURNAL OF ENVIRONMENTAL SCIENCES, 2011 Biological control is beginning to be more commonly used, especially in greenhouses. The inundatory release of insects, especially parasitoids, requires a thorough knowledge of their biology and of mass-rearing techniques. Moreover, to synchronize releases with host presence, the parasitoids have to be kept in cold storage.

Specificity of Multi-Modal Aphid Defenses against Two Rival Parasitoids. [PDF]
PLoS ONE, 2016 Insects are often attacked by multiple natural enemies, imposing dynamic selective pressures for the development and maintenance of enemy-specific resistance.

Entomologia Experimentalis et Applicata, EarlyView.Insect herbivores rely on olfactory cues to locate natural‐enemy‐free spaces for feeding or ovipositing; conversely, natural enemies detect herbivores by chemical cues from damaged plants or from the herbivores themselves. Based on the reviewed findings, we suggest that herbivores and natural enemies converge towards using specific olfactory cues. This

Ecological Entomology, EarlyView.Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.
