NATURAL ENEMIES OF DIURAPHIS NOXIA (STERNORRHYNCHA: APHIDIDAE) IN SLOVAKIA [PDF]

Journal of Central European Agriculture, 2009
A study from 2002 documented the occurrence of natural enemies (parasitoid wasps, predatory fl ies, entomopathogenic fungi) associated with colonies of the Russian wheat aphid, Diuraphis noxia (Kurdjumov, 1913) (Sternorrhyncha: Aphididae), in the spring ...

Decoding chemical profiles in insect‐induced gall development: Insights from Phacopteron lentiginosum–Garuga pinnata interactions

Entomological Science, Volume 29, Issue 3, September 2026.
Analysis of volatile and non‐volatile metabolites across three developmental stages (3rd, 4th and 5th instar nymphal stages) of leaf galls induced by Phacopteron lentiginosum on Garuga pinnata revealed that the 3rd stage exhibited the highest chemical diversity and concentration followed by 4th and 5th stages.

Les pucerons des cultures protégées et leurs ennemis en Tunisie [PDF]

Tropicultura, 1993
Aphids in the protected crops and their natural enemy in Tunisia. The importance of damage caused by aphids in protected crops, led us to carry out the inventory of aphids as well as the antagonists and to study the distribution of aphid population of ...

Survival to parasitoids in an insect hosting defensive symbionts: a multivariate approach to polymorphic traits affecting host use by its natural enemy. [PDF]

PLoS ONE, 2013
Insect parasitoids and their insect hosts represent a wide range of parasitic trophic relations that can be used to understand the evolution of biotic diversity on earth.

Insectary Plant Species Preferences of Predators and Parasitoid Families in a Mediterranean Horticultural Agroecosystem

Journal of Applied Entomology, Volume 150, Issue 6, Page 803-815, July 2026.
ABSTRACT The use of insectary plants to provide alternative food and shelter resources for enhancing natural enemy activity has been established as a common practice in IPM. Candidate flowering plant species have been screened and evaluated for their contribution to enhance life parameters of beneficial insects.

Trans-generational effects of mild heat stress on the life history traits of an aphid parasitoid. [PDF]

PLoS ONE, 2013
Temperature changes are common in nature and insects are particularly exposed and sensitive to such variations which can be potential stresses, ultimately affecting life history traits and overall fitness.

The Effects of LED Daylength Extensions on the Daily Activity Patterns of a Greenhouse Biological Control Agent, Aphidius matricariae

Entomologia Experimentalis et Applicata, Volume 174, Issue 5, Page 398-410, May 2026.
We used automated activity monitors to examine how light‐emitting diode illumination affects the daily locomotor activity of the parasitoid biocontrol agent Aphidius matricariae. We compared 4‐ to 20 h broad‐spectrum white (BSW) photoperiods, and 12 h BSW photoperiods extended with an additional 6 h of red‐blue, red‐green‐blue, or BSW light, or no ...

Effects of artificial diet containing GNA and GNA-expressing potatoes on the development of the aphid parasitoid Aphidius ervi Haliday (Hymenoptera : Aphidiidae)

, 2001
Aphid parasitoids are important biological control agents. The possibility arises that whilst foraging on insect-resistant transgenic plants, they are themselves at risk from direct and indirect effects of the expression of a transgene used to control ...

Cereal aphids (Hemiptera: Aphidoidea) in Serbia: Seasonal dynamics and natural enemies

European Journal of Entomology, 2008
During 1989-2006 the number of live aphid, mummies, aphid specialist predators and their parasitoids in cereal fields in Serbia were recorded. S. avenae and M. dirhodum were the most common, both on wheat and rye crops.

Potential Drivers of Successful Biocontrol: A Perspective on Parasitoids

New Zealand Journal of Zoology, Volume 53, Issue 1, March 2026.
Parasitoids are central to classical biological control, yet predicting their long‐term effectiveness post release remains challenging. In Aotearoa New Zealand, three Microctonus (Hymenoptera: Braconidae) species have been used against pest weevils, but key aspects of their biology remain poorly understood.
